Bonneville Joint Grew 78% in 24 Years, Then Stopped

Fri, 27 Feb 2026 12:00:00 GMT

Bonneville Joint District^↗ has 13,511 students. It is Idaho's third-largest district, behind only West Ada and Boise. Twenty-four years ago, it was seventh, with 7,568 students, sitting behind both Idaho Falls^↗ and Pocatello^↗ in eastern Idaho's enrollment hierarchy. It passed Idaho Falls in 2012 and Pocatello in 2018, by a margin of just 31 students.

The 78.5% growth rate over 24 years nearly triples the state's 27.6% gain over the same period. But the streak ended in 2024. Bonneville peaked at 13,801 in 2023 and has declined for three consecutive years, losing 290 students. The question is whether this is a pause or a turning point.

An 18-year run

From 2003 through 2020, Bonneville Joint grew every single year. The 18-year consecutive growth streak is the second-longest among Idaho districts over the period, tied with West Ada and Vallivue and trailing only Jefferson County (19 years).

The growth came in waves. From 2002 to 2010, the district added 2,320 students (+30.7%), fueled by Idaho's pre-recession housing boom and Ammon's emergence as a bedroom community for Idaho Falls. From 2010 to 2020, another 3,437 students arrived (+34.8%), accelerating even through years when the state's growth moderated. The single largest annual gain was 721 students in 2015, a 6.5% jump over the prior year.

The district's share of Idaho's total enrollment climbed steadily: 3.1% in 2002 to 4.3% in 2026. Bonneville Joint grew faster than the state in almost every year of the streak.

The engine: Ammon and INL

Bonneville Joint District covers the communities south and east of Idaho Falls, including Ammon. Census estimates place Ammon's 2024 population at about 20,100, up from 6,187 in 2000. That 225% population increase over 24 years made it one of the fastest-growing small cities in the Mountain West.

The Idaho National Laboratory, located about 50 miles west of Idaho Falls, generates over $4 billion in annual economic impact and is one of the region's largest employers. Federal investment in nuclear research and clean energy has expanded INL's workforce over the past decade, drawing engineers and scientists with school-age children to the Idaho Falls metro area. The Idaho Falls MSA's population reached 171,233 in 2024, growing at 1.6% annually.

Proximity to BYU-Idaho in Rexburg also shapes the district's enrollment indirectly. BYU-Idaho enrolled 24,111 campus students in fall 2024, its largest incoming class ever. Many graduates settle in the Idaho Falls area, and the region's LDS population tends to have above-average family sizes, which sustained school enrollment even as birth rates fell elsewhere.

Eastern Idaho's hierarchy, rewritten

Bonneville Joint's rise reshuffled the region's enrollment rankings. In 2002, Pocatello (12,210) and Idaho Falls (10,648) were eastern Idaho's dominant districts, with Bonneville a clear third at 7,568. By 2026, the order has fully inverted: Bonneville leads at 13,511, Pocatello has dropped to 11,437 (-6.3% since 2002), and Idaho Falls has fallen to 9,751 (-8.4%).

The gap between Bonneville and Idaho Falls is now 3,760 students. In 2011, the year before the crossover, Bonneville trailed by just 14.

Among all Idaho districts currently enrolling more than 5,000 students, Bonneville's 78.5% growth ranks third behind Vallivue (+175.2%) and Kuna (+81.4%). Both of those are Boise-area suburbs that roughly doubled or tripled off smaller bases. Bonneville is the only district east of the Sawtooths in the top five.

Three red bars

The 2024-2026 period introduced something Bonneville had rarely experienced: consecutive decline. The district lost 138 students in 2024, 59 in 2025, and 93 in 2026. The total three-year decline of 290 students (-2.1% from peak) is mild compared to Boise's 4,604-student loss (-17.5% since 2002), but the pattern is new.

The most likely driver is the same force hitting districts statewide: fewer kindergarteners. Bonneville's kindergarten class peaked at 996 in 2013 and has not recovered. In 2026, the district enrolled 824 kindergarteners, a 17.3% decline from that peak.

Eastern Idaho's birth rate decline is steeper than the rest of the state. Idaho's overall birth rate fell 29% between 2007 and 2021, but eastern Idaho's dropped 31%, the largest regional decline. The children born during the 2007 peak are now in high school. The children born in the subsequent trough are the ones entering kindergarten.

A pipeline that tells two stories

Bonneville's grade-level data reveals a district that is simultaneously growing at the top and shrinking at the bottom. Grade 12 enrollment nearly doubled from 614 in 2002 to 1,161 in 2026, an 89.1% increase. Kindergarten grew only 44.1% over the same span, from 572 to 824.

The gap matters because today's kindergarten class becomes tomorrow's 12th-grade class. If incoming cohorts remain near 824 while graduating classes are 1,161, the district will lose roughly 300 students per cycle just from pipeline compression, even without any outmigration.

The district has been planning for continued growth. In August 2023, voters approved a $34.5 million bond to build a new 700-student elementary school near Iona. The rationale was that existing schools were at or over capacity, with several relying on portable classrooms. Whether a district that is now losing students will fill a new elementary school is an open question. It may simply relieve overcrowding at existing buildings rather than absorb new growth.

A new school for a shrinking pipeline

In August 2023, Bonneville voters approved a $34.5 million bond to build a 700-student elementary school near Iona. The rationale was that existing schools were at or over capacity, with several relying on portable classrooms. The bond passed during the district's peak year. Three consecutive declines later, the school is under construction for a district that is losing students.

It may simply relieve overcrowding at existing buildings rather than absorb new growth. The 824 kindergarteners entering in 2025-26 is the district's smallest class since 2008. INL's expansion and Ammon's housing pipeline provide structural support that Boise and Pocatello lack. But 78.5% growth over 24 years was built on a birth rate that has fallen 31% in eastern Idaho. The new elementary school will open into that arithmetic.

One Network, Seven Campuses, 3,240 Students

Fri, 20 Feb 2026 12:00:00 GMT

In 2017-18, a single charter school in Pocatello enrolled 143 students. By 2025-26, Gem Prep: Pocatello^↗ had become the anchor of a seven-campus network stretching from the Snake River Plain to the Treasure Valley, enrolling 3,240 students across four cities and an online program. No other charter operator in Idaho has replicated across multiple locations. Gem Innovation Schools, the organization behind Gem Prep, is the state's first and only charter management organization.

That 2,166% growth over eight years occurred while the state's total enrollment grew just 3.8%. The four traditional districts where Gem Prep operates, West Ada^↗, Nampa^↗, Pocatello^↗, and Twin Falls^↗, collectively lost 4,748 students over the same period.

The Meridian footprint

Three of Gem Prep's seven campuses sit within or near West Ada School District's boundaries in Meridian, and they tell the most striking part of the network's story. The original Gem Prep: Meridian campus opened in 2018-19 with 269 students. Meridian North followed in 2021-22; Meridian South in 2022-23. Together, the three Meridian campuses now enroll 1,485 students, 45.8% of the entire network.

West Ada, Idaho's largest district, peaked at 40,326 students in 2019-20 and has since lost 2,407, a 6.0% decline. Gem Prep is not the only factor. Birth rate trends, pandemic disruption, and private school options all contribute. But the Meridian cluster's growth, from zero to nearly 1,500 students in seven years, represents a visible shift in family choices in Idaho's fastest-growing metro area.

A dual-credit pitch in a choice-friendly state

Gem Prep's model centers on blended learning and early college credit. Students use computer-adaptive software alongside direct instruction, and by 11th and 12th grade they take dual-credit courses through the Idaho Digital Learning Alliance at no cost to families.

"Our goal would be that anyone who wants a Gem Prep education has access to a Gem Prep education, regardless of what part of the state you live in, regardless of your family dynamics." -- Dr. Jason Bransford, Gem Prep CEO, J.A. and Kathryn Albertson Family Foundation

The network reports that 50% of its 2023 graduates earned an associate's degree alongside their high school diploma, with the average graduate accumulating 46 college credits and $36,000 in scholarship offers. Those figures come from the network itself and have not been independently audited, but they illustrate the value proposition that has filled seven campuses.

The state's political environment has been hospitable. Idaho enacted a $5,000 per-student private school tax credit in February 2025 (HB 93), capped at $50 million annually, signaling legislative appetite for school choice broadly. Charters, as public schools, do not need tax credits to attract families. But they operate in a market where the legislature has made clear it views parental choice as policy priority.

Where the growth came from, and where it stalled

Gem Prep's expansion has followed a recognizable pattern: open a new campus, fill it to roughly 400-500 students over three to four years, then open another. The Nampa campus opened in 2018-19 at 363 students and now enrolls 523. Twin Falls, the newest brick-and-mortar location, opened in 2023-24 at 165 and reached 412 in just two years, a 149.7% increase.

But the founding Pocatello campus is showing strain. After peaking at 476 students in 2024-25, it dropped 70 students (14.7%) in 2025-26 to 406, its lowest enrollment since 2020-21. Whether this reflects local market saturation, the departure of a long-tenured principal to lead the upcoming Idaho Falls campus, or simply a cohort fluctuation is unclear from enrollment data alone.

The network's total growth is also decelerating. Gem Prep added 655 students in 2023-24, driven largely by Meridian South and Twin Falls opening or ramping up. In 2024-25, growth slowed to 240. In 2025-26, just 100. Without a new campus opening, existing locations appear to be approaching capacity. An Idaho Falls campus broke ground in September 2025 for a fall 2026 opening, and the network has announced plans for a Rexburg location in 2027.

One operator, one-eighth of the sector

Gem Prep now enrolls 3,240 of Idaho's roughly 26,200 charter students, about 12.4%, making it the largest brick-and-mortar charter operator in the state. (Idaho Home Learning Academy, a virtual charter, enrolls 7,504 students but is a single-site operation.) Idaho's data system does not flag Gem Prep as a charter because the name lacks the word "charter," so official charter counts understate the sector. Including Gem Prep, charters serve about 8.3% of Idaho's 314,097 students.

That concentration rose quickly. Gem Prep was a single campus with 143 students in 2018. By 2024, the network enrolled 19.1% of the state's name-flagged charter students. The Idaho Home Learning Academy charter split from Oneida County District in 2025, expanding the charter enrollment denominator and moderating the share.

Idaho's charter sector has grown from 5 schools enrolling 674 students in 2002 to at least 39 charter entities enrolling over 26,000 in 2026. The count of name-flagged charters has held steady at 32 since 2024, suggesting growth is coming from existing schools expanding rather than new operators entering.

The divergence question

The sharpest tension in the Gem Prep story is this: every traditional district where the network operates has shrunk since 2020, while Gem Prep grew by 1,784 students over the same period. West Ada lost 2,407 students. Nampa lost 1,566. Pocatello lost 1,068. Twin Falls lost 846.

It would be an oversimplification to attribute all of those losses to charter competition. Statewide enrollment fell by 1.2% in 2025-26 alone, driven by demographic trends that predate charter expansion. But in Meridian specifically, where three Gem Prep campuses now enroll nearly 1,500 students in a district that has lost 2,407 since its peak, charter growth is clearly part of the enrollment equation.

"[Idaho charter schools] squashed fears, filled needs and created alternatives." -- Idaho Ed News, December 2023

One dynamic that enrollment data cannot measure: whether families choosing Gem Prep would otherwise attend their neighborhood school or would have left the public system entirely for homeschooling or private options. Idaho's charter waiting lists exceeded 10,700 students in 2023-24, with roughly three-quarters of schools reporting. Demand appears to outstrip supply, but the data does not reveal how many of those waitlisted families end up in the traditional district versus opting out altogether.

The pipeline narrows at the top

Gem Prep's grade-level structure reveals a network still growing into its K-12 model. In 2025-26, K-5 enrollment totals 1,826 students. Grades 6-8 enroll 933. But the high school grades, 9-12, enroll just 481, with only 89 seniors.

That top-heavy elementary profile is partly by design: most campuses opened as K-6 or K-8 programs and are adding upper grades incrementally. But it also means the dual-credit promise that anchors Gem Prep's pitch reaches a relatively small number of students so far. As current elementary cohorts age into high school, the network's high school enrollment should grow substantially without new campuses, provided retention holds.

Campus eight breaks ground

In September 2025, construction began on Gem Prep's Idaho Falls campus, scheduled to open in fall 2026. A Rexburg location is planned for 2027. The Idaho Falls market is different from the Treasure Valley: smaller, more concentrated, and anchored by Idaho National Laboratory's workforce. Idaho Falls School District enrolled 9,751 students. Bonneville Joint enrolled 13,511. Together they form a metro area one-fifth the size of the West Ada market where three Gem Prep campuses already operate.

The Pocatello founding campus, meanwhile, dropped 70 students in 2025-26, its steepest loss. Whether the original location is saturated or simply cycling through a weak cohort will become clearer as the network's attention shifts east. Gem Prep added just 100 students statewide this year, its slowest growth ever. Eight campuses and 3,240 students later, the startup phase is over. What follows will depend on whether the model travels.

35 Districts at Record Highs, 38 at Record Lows

Fri, 23 Jan 2026 12:00:00 GMT

Vallivue School District^↗ enrolled 10,700 students this fall, an all-time high. Twenty miles east, Boise Independent District^↗ enrolled 21,717, an all-time low. The two districts sit in the same metro area, draw from the same labor market, and compete for the same families. One has grown 175.2% since 2002. The other has lost 4,604 students, 17.5% of its peak enrollment, and has not grown in nine years.

This is the Idaho enrollment story in miniature. Statewide, 35 districts hit record-high enrollment in 2025-26 while 38 hit record lows. The numbers are almost balanced. The weight is not: the 38 districts at all-time lows collectively serve 86,114 students, 27.4% of the state's enrollment. The 35 at all-time highs serve just 33,738, or 10.7%.

The lopsided split

Idaho added 72,795 students between 2002 and its 2023 peak of 318,979, a 29.6% increase in two decades. That growth has evaporated. The state lost 4,882 students over the past three years, including 3,970 in 2025-26 alone, the largest single-year decline in at least 25 years of data.

Of 190 districts with enrollment in both 2024-25 and 2025-26, 125 declined, 60 grew, and five were flat. The losses are concentrated at the top: West Ada, the state's largest district, lost 538 students. Boise lost 513. Nampa lost 256. Twin Falls lost 250. Eight of the state's 10 largest traditional districts shrank.

The districts at record highs, meanwhile, are small. Their median enrollment is 492 students. Only two, Vallivue and Middleton, exceed 4,000.

Who is growing, and how

Of the 35 districts at all-time highs, 31 are charter schools, virtual academies, or charter-like entities. Four are traditional districts: Vallivue (10,700), Middleton^↗ (4,401), Boundary County^↗ (1,697), and Avery (32).

The charter/choice category includes a range of models. Idaho Arts Charter (1,421), Compas Public Charter (1,289), and North Star Charter (1,143) are brick-and-mortar schools. iSucceed Virtual High School (1,785) and Idaho Virtual High School (833) are fully online. The seven Gem Prep campuses, which collectively enroll 3,240 students across the state, are listed as traditional districts by the state but operate as a charter network.

The demand for alternatives remains unmet. At least 10,711 students sat on charter school waitlists at the start of the 2025-26 school year, and federal funding is supporting the addition of 13 more charter schools and 5,900 seats by 2028.

The biggest districts are the ones shrinking

The concentration of record lows among Idaho's biggest districts is the most consequential pattern in these numbers. Boise^↗, Pocatello^↗ (11,437), and Idaho Falls^↗ (9,751), the state's second, fifth, and seventh largest districts, are all at their lowest enrollment in at least 25 years.

Boise's decline is the longest and deepest. The district peaked at 26,321 students in 2002, the first year in the dataset, meaning its actual peak may have been higher. It has declined in nine consecutive years, losing 4,458 students since 2017, a 17.0% drop. Average daily attendance last year fell to 20,317, the lowest since the 1983-84 school year.

A demographic mismatch Idaho cannot build its way out of

Idaho was the fastest-growing state in the country between 2012 and 2022. But the growth skews old. Between 2020 and 2024, youth contributed only 9.3% of total population growth, the smallest share of any age category, while adults 65 and older accounted for the largest share at 17.4% growth.

The mechanism is straightforward. Many of Idaho's new residents are retirees fleeing higher-cost states, drawn by lower taxes and housing that, while expensive by Idaho standards, remains cheaper than coastal markets. Labor economist Sam Wolkenhauer put it starkly: "In Idaho, there are 68% as many infants as there are 18 year olds." Each graduating class is larger than the kindergarten cohort replacing it. In 2026, Idaho enrolled 25,316 twelfth graders and 20,184 kindergartners, a gap of 5,132 students that has widened every year since 2018.

Housing costs compound the problem inside the Boise metro. Rising prices in Ada County have been pricing young families into Canyon County suburbs like Vallivue and Middleton, or out of the metro entirely. Nampa, once a more affordable alternative, has itself begun losing students, shedding 256 this year and repurposing four elementary schools for other uses.

Rural districts on a longer clock

Twenty-nine of the 38 districts at all-time lows have full 25-year histories in the data, making their declines not statistical artifacts of short timelines but confirmed long-term trends. These 29 districts have lost an average of 26.7% from their peak enrollment.

Salmon District^↗, in the Lemhi Valley, enrolled 1,143 students in 2002 and 609 in 2026, a 46.7% decline over 24 years. Caldwell^↗ peaked at 6,428 in 2008 and has since lost 1,496 students, 23.3% of its enrollment. Soda Springs, Marsh Valley, Payette, St. Maries: the list of small and mid-size districts that have never been smaller runs the length of Idaho's rural geography.

These districts face a structural challenge distinct from Boise's housing-driven losses. Idaho's population grew 45% between 2002 and 2022, but births increased only 7% over the same period. The birth rate fell from 16.6 per 1,000 in 2007 to 11.8 in 2021, a 29% decline. For rural districts already operating on thin margins, Idaho's ranking of 49th or 50th nationally in per-pupil funding since 2020 leaves little room to absorb the losses.

In the past six months alone, at least seven Idaho school districts have announced or considered school closures, including Caldwell, Coeur d'Alene, Boise, and Marsh Valley, four of which appear on the all-time-low list.

The acceleration underneath

The near-symmetry of 35 record highs and 38 record lows obscures an acceleration. In 2023, 15 districts hit record highs and six hit record lows. In 2025, those numbers were 23 and 14. In 2026: 35 and 38. The split is widening in both directions simultaneously.

Seven districts have announced or considered school closures in the past six months alone. Nampa shuttered four buildings. Caldwell, Coeur d'Alene, Boise, and Marsh Valley are all weighing cuts. On the other side, Vallivue's two new elementary schools opened in August, and Gem Prep broke ground on an eighth campus in Idaho Falls.

The 121 districts in the middle, 61.9% of statewide enrollment, are the pool from which future records will be drawn. Most of them lost students this year. The new residents keep coming. Their children, increasingly, do not.

Idaho's Growth Era Is Over

Fri, 19 Dec 2025 12:00:00 GMT

For 18 consecutive years, Idaho's public schools grew. Every fall from 2003 through 2020, more students showed up than the year before. The state added 65,807 students during that stretch, a 26.7% expansion that mirrored Idaho's reputation as one of the fastest-growing states in the country. That era is over.

Idaho's K-12 enrollment fell to 314,097 in 2025-26, a decline of 3,970 students from the prior year. It is the steepest single-year drop in the 25 years of data available, nearly triple the size of the COVID-era loss in 2020-21 and 6.7 times larger than the decline recorded just one year earlier. Enrollment has now fallen in three consecutive years since peaking at 318,979 in 2022-23, erasing 4,882 students, or 1.5% of the peak total.

The acceleration no one planned for

The pattern of the last three years is not gradual. It is accelerating. In 2023-24, Idaho lost 319 students, a rounding error that could be dismissed as a plateau. In 2024-25, the loss grew to 593. In 2025-26, it exploded to 3,970, a 1.25% decline that dwarfs anything in the dataset.

During Idaho's growth era, the state averaged 3,563 new students per year from 2003 to 2012, and 3,772 per year from 2013 to 2020. The post-pandemic reversal has averaged a loss of 1,627 students per year over the last three years. For budget officers accustomed to planning around growth, this is not a minor adjustment. It is a structural break.

Two-thirds of Idaho's 192 districts and charter schools lost enrollment in 2025-26, the highest share in the dataset. In the post-COVID rebound year of 2021-22, only 29.4% of districts declined. Just four years later, 65.8% are shrinking.

Boise at an all-time low

The decline is concentrated at the top. The 10 districts that lost the most students in 2025-26 accounted for 75% of the statewide loss. The five largest losers alone represented half.

West Ada District^↗, Idaho's largest, lost 538 students in 2025-26 and 1,238 since the 2023 peak, a 3.2% decline. Boise Independent District^↗, the second-largest, is at an all-time low of 21,717 students after losing 1,168 from its peak, a 5.1% drop. Nampa School District^↗ has shed 945 students since 2023, a 7.0% decline. Pocatello District^↗ has lost 896, or 7.3%. Twin Falls District^↗ is down 588, or 6.3%.

In all, 38 districts hit all-time lows in 2025-26, including three of the state's five largest. Thirty-five districts reached all-time highs, but most of those are small charter schools and rural districts where a handful of students can set a record.

The one standout among large districts is Vallivue School District^↗ in Caldwell, which added 807 students since 2023, an 8.2% gain. Vallivue's growth aligns with Canyon County's status as a more affordable alternative to Ada County (Boise). But Vallivue is the exception. Eight of the ten largest traditional districts have declined since the peak.

Fewer kindergarteners, more seniors

The clearest signal that Idaho's decline is structural, not cyclical, comes from the grade-level pipeline. In 2002, Idaho enrolled roughly equal numbers of kindergarteners and 12th graders: 17,844 and 17,622. For 15 years, kindergarten outpaced Grade 12, a sign that more students were entering the system than leaving it.

That relationship inverted in 2018. Grade 12 enrollment surpassed kindergarten and has stayed ahead every year since. In 2025-26, the gap reached its widest point: 25,316 seniors versus 20,184 kindergarteners, a difference of 5,132 students. The K-to-G12 ratio has fallen to 0.80, meaning for every five seniors graduating out of Idaho schools, only four kindergarteners are entering.

Kindergarten peaked at 22,537 in 2012-13 and has fallen 10.4% since. Grade 12, by contrast, is at its highest point ever. Those 12th graders were born in 2007-08, the peak years for Idaho births. Every graduating class after this one will come from smaller birth cohorts.

A growing state that produces fewer students

Idaho's population has grown faster than nearly every other state's, expanding 21.5% from 2012 to 2022 and surpassing two million residents in 2024. The paradox is that almost none of that growth translated into school enrollment. According to an analysis by Idaho@Work, 90% of Idaho's population growth from 2019 to 2022 came from adults over age 18. The state's population rose 45% from 2002 to 2022. Births rose just 7% over the same period.

The birth rate tells the story most directly. Idaho recorded more than 25,000 births in both 2007 and 2008, its highest levels on record. By 2021, the rate had fallen to 11.8 per 1,000, a 29% decline from the 2007 peak of 16.6. That generation of 25,000-birth cohorts is now aging out of K-12, and the smaller cohorts behind them are what kindergarten classrooms are seeing.

Housing costs compound the demographic squeeze. State Superintendent Debbie Critchfield told Idaho EdNews that rising costs "have made it harder for young families to stay or settle in Idaho, which contributes to smaller kindergarten cohorts." Ada County median home prices hover around $535,000. The newcomers driving Idaho's population boom are disproportionately retirees and remote workers, not families with school-age children.

"We know enrollment directly impacts state funding." — Superintendent Debbie Critchfield, Idaho EdNews, November 2025

The funding formula amplifies the pain

Enrollment decline arrives at a particularly bad time for Idaho districts. The state's funding formula, which ties school budgets to average daily attendance rather than enrollment, means districts lose money twice: once from fewer students, and again from the gap between enrollment and attendance. Statewide, attendance averages about 92-93% of enrollment. Districts get funded on the lower number.

When the Legislature and State Board of Education allowed a pandemic-era enrollment-based funding rule to expire, the shift back to attendance-based funding cost districts an estimated $162 million. Quinn Perry of the Idaho School Boards Association warned of the impact:

"We knew and made our best attempts to warn state leaders that shifting back to attendance would bring a dramatic drop in how state funding is distributed, but it's quite distressing to see the difference." — Quinn Perry, Idaho EdNews, January 2024

Most of Idaho's districts face losses under the attendance formula. Only about 50 smaller districts benefit from attendance-based funding. For a district like Boise, already at an all-time enrollment low, the combination of fewer students and a funding formula that discounts those who remain is a compounding fiscal problem.

A state that stopped building for growth

The Board of Education's 2024 demographic projections suggested no enrollment cliff was imminent, noting that migration could offset falling birth rates. The 2025-26 data challenges that optimism. The 3,970-student loss in a single year exceeds what the projections anticipated.

Nampa closed four elementary schools in the summer of 2024. Boise cut 27 positions. Coeur d'Alene is weighing budget reductions. These are not districts that planned for contraction. They budgeted for a growth state, and for 18 years the growth came. It stopped coming, and the infrastructure built for 319,000 students now serves 314,000, with a kindergarten pipeline that keeps narrowing.
