Boulder Valley, Poudre and Adams 12 all have closure or consolidation plans in the works this year. Douglas County and Denver have also recently shut down several low-enrollment schools. The pressure reflects a statewide demographic shift: Colorado’s fertility rate is now 1.4 children per woman, below the 2.1 rate generally needed to keep a population steady without migration.

In Jeffco, declining enrollment was compounded by years of building more school capacity than the district needed. At its mid-2010s peak, the district had nearly 100,000 seats for about 86,000 students. By 2022, enrollment had fallen, and dozens of elementary schools were operating below half capacity, said former school board member Susan Miller.

“When you start to be below 82%, particularly in an elementary school, you're starting to actually fund the building as opposed to funding children,” Miller said, pointing to the ongoing costs of classrooms, utilities and other facilities.

The district first closed Allendale Elementary in 2021 and Fitzmorris Elementary in 2022. It then approved a broader plan that shuttered 21 schools at the end of the 2022-23 school year. Former district chief of staff Lisa Relou said the earlier closures revealed how many small schools could be combined without filling the receiving buildings to capacity.

For parents, the savings did not erase concerns about disruption, fairness and the loss of valued community institutions. Mollie Crampton opposed closing Vivian Elementary in Lakewood, where her children had attended. She said she worried the decision would take an important, diverse community away from vulnerable students.

Vivian was a Title I school, serving many students from low-income households. Crampton said it had high academic standards and was making progress in addressing learning gaps. Rather than send her children to the school assigned to receive Vivian students, her family chose another school that better reflected its values. She said the family ultimately found a school community it loves, while remaining concerned about the possibility of future closures.

Miller said the district’s process was imperfect and that officials had little time to plan after federal pandemic aid began drying up in 2022. She said she wished the district had started earlier, allowing more time to examine educational outcomes and hear from families. Jeffco’s 11-week decision process was also exhausting for many parents, Relou said.

Declining birth rates are unlikely to rebound enough to reverse the trend, said Colorado State Demographer Neal Marquez. He linked the drop, which began around 2007, to economic pressures, wider access to long-acting contraception and people delaying parenthood. Lower birth rates mean smaller classes will continue moving through the school system in coming years, putting more buildings under pressure.

Consolidation can also bring benefits to receiving schools, though integrating students takes work. Lawrence Elementary in Arvada absorbed students from two nearby schools that closed. Former principal Chris Benisch said the influx initially challenged the school and its test scores, but the added enrollment brought a larger budget and access to more resources. By the time he retired last spring, he said, test scores had recovered.

The competing outcomes underscore what is at stake for districts now considering closures: keeping underused buildings open can drain funds from classroom services, while consolidating schools can unsettle students and families and deepen concerns about which communities bear the burden. Relou said a clear process centered on students can help, even when the decision is unpopular.

Jeffco still has underused schools to address, Miller said. But Relou argued that without closing 21 schools and saving $20 million annually, the district would now be in a much more difficult financial position. For families, the results have varied: some have adjusted well, while others say the strain was not worth repeating.
