This is part of The MDEdTribune's series on Maryland's 2025-26 enrollment data.

Frederick^↗ County Public Schools lost 123 students in 2025-26. By itself, a 0.3% dip barely registers. But Frederick had been Maryland's lone large-district growth story — 4,310 students added between 2022 and 2025, faster than any other system in the state. The streak is over, and with it, Maryland's last engine of enrollment growth has stalled.

The loss leaves Kent County, a rural Eastern Shore system with 1,609 students, as the only one of Maryland's 24 districts that added enrollment this year. It gained 18.

The four-year run and what fueled it

Frederick's growth streak began in 2022, when the district rebounded from a small pandemic-era dip of 271 students with a surge of 1,777 in a single year. That was the largest one-year gain in Frederick's recent history, and it pulled the district well past its pre-pandemic enrollment. The pace slowed each year after: 1,425 in 2023, 770 in 2024, 338 in 2025. The deceleration was steady enough that the 2026 reversal looks less like a sudden shock than the end of a fading tailwind.

Over the full decade from 2016 to 2026, Frederick added 6,875 students, a 17.4% gain. No other Maryland district comes close. The next-best performer, Anne Arundel^↗, gained 3,820 (4.9%). Frederick's share of statewide enrollment climbed from 4.65% to 5.45% during a period when the state total barely moved.

That growth was driven in part by the I-270 corridor, the interstate that connects Frederick to Montgomery County and the Washington, D.C., suburbs. As housing costs in Montgomery^↗ County rose, families with school-age children moved north along the corridor, trading longer commutes for affordable homes and highly rated schools. Frederick County has been building schools to keep up: some elementary schools have reached 170% capacity, and the district is opening an 882-seat elementary school in August 2026 alongside a new facility, Linganore Creek Elementary, with capacity for nearly 900 students.

The corridor divergence

The I-270 story is most visible when Frederick and Montgomery are placed side by side. In 2016, Montgomery County enrolled 152,038 students, nearly four times Frederick's 39,470. A decade later, Montgomery sits at 151,983, essentially unchanged, while Frederick has grown to 46,345.

But the indexed comparison masks a sharper recent turn. Montgomery lost 2,808 students in 2025-26 alone, a 1.8% decline. WTOP reported that Montgomery County Public Schools Superintendent Thomas Taylor described the enrollment situation as a "sharp decrease," with the system projecting a loss of 6,000 students by 2031. Montgomery's decline accelerated this year in part because international student enrollment fell sharply, a pattern multiple Maryland superintendents attributed to federal immigration enforcement.

Frederick had been the beneficiary of Montgomery's decline. Whether Frederick's own reversal reflects a saturation of the spillover pipeline, a broader demographic shift, or something specific to 2025-26 conditions is not yet clear from the data alone.

A statewide shutout

Frederick's loss is easier to understand in the context of what happened across Maryland. The state posted its largest non-pandemic enrollment drop in 2025-26, a 1.1% decline. Only one of 24 districts gained students, the worst ratio in at least a decade. In the pre-pandemic years of 2017-2020, between 14 and 17 districts were gaining students annually. Even in 2025, half of Maryland's districts were still growing.

The three largest losses came from the state's three largest suburban systems: Montgomery, Baltimore County^↗, and Prince George's^↗. Together, those three account for nearly two-thirds of the statewide loss. Frederick's 123-student decline looks modest by comparison, but it closed the last gap in a wall of red.

The Baltimore Banner reported that the statewide decline nearly doubled initial projections. Superintendents pointed to declining birth rates, federal immigration enforcement, and a 51% increase in homeschooled students since the pandemic as contributing factors.

The kindergarten signal

Frederick's kindergarten enrollment offers a more specific warning. In 2022, 3,257 kindergarteners enrolled, the highest count in the dataset. By 2026, that number has fallen to 3,177, still well above the pre-pandemic level of 2,754 in 2016 but trending down from the post-COVID surge.

The kindergarten pipeline is the leading indicator for total enrollment five to six years out. If fewer five-year-olds are entering Frederick schools, the growth that defined the district over the past decade cannot sustain itself through migration alone. Maryland's birth rate has been declining since 2016, and the children born during the pandemic years of 2020 and 2021, when births dipped further, are now entering kindergarten statewide.

Frederick is not immune to this demographic undertow. The district's kindergarten class remains 15.4% larger than it was in 2016, but the year-over-year trajectory since 2022 has been flat to declining.

One year or a turning point?

The 123-student loss is small enough that it could reflect a one-year blip rather than a structural turn. Frederick's total enrollment in 2026 (46,345) is still 9.2% above its 2020 level, a cushion that only three other Maryland districts can claim: Wicomico (+1.2%), Carroll (+1.0%), and Charles (+0.5%). Frederick remains, by far, the state's best-performing district over the past decade.

What the enrollment data alone cannot answer is whether the I-270 migration pipeline has genuinely slowed, or whether 2026 caught an unusually weak year. Frederick County is still building schools and fast-tracking construction with $175 million in capital investment, a signal that local planners still expect growth. State enrollment projections from the Maryland Department of Planning forecast Frederick adding 6,260 students by 2033, the largest projected gain of any district.

If those projections hold, 2026 will be a pause, not a peak. If they don't, the state of Maryland will have lost its last district-level growth story, and the fiscal math of the Blueprint for Maryland's Future, which funds schools based on enrollment counts, will look different for every district in the state.
