How full are our schools, and how big are classes?
Enrollment trends, building utilization and class sizes, from the District’s own dashboards and section lists.
High-utilization buildings don’t have bigger classes, the smallest classes are at the dual-language schools, and one closure nets roughly $0.2–0.7M a year after busing.
Every year for a decade, ETHS’s freshman class has outnumbered the prior year’s D65 8th grade, by about 152 students (~20%) on average. That is consistent with, but doesn’t prove, a trust-driven flow from private K-8 to ETHS.
The Jupyter notebook behind the enrollment and salary figures.
D65’s enrollment decline compared with peer districts. At a z-score of −2.23, it is more than two standard deviations below the peer average: not typical of the region.
