Dr. Glassmeyer presented beginning-of-year enrollment trends to the Mesa Public Schools Governing Board on Sept. 23 and described cohort retention, day-15 counts and the district’s analytic approach.

Key data presented: Administration reported an October 1 projection of approximately 51,663 students for the year and a Day-15 headcount that showed notable decreases in kindergarten (about an 11.5 percent decline year over year, or roughly 404 students) and smaller cohorts across other early grades. Staff highlighted a cohort example: a group that numbered 4,411 on Oct. 1 several years ago was replaced this year by only 3,404 incoming kindergarten students — a shortfall of roughly 1,000 students in that comparison.

Retention measures: District staff showed cohort-retention metrics (students reenrolled from one year to the next) and noted that full-academic-year (FAY) attendance correlates with stronger outcomes. Dr. Glassmeyer explained that preschool-to-kindergarten transitions are harder to measure because children may take more than one year in preschool; preschool retention figures are therefore an estimate rather than a direct denominator for incoming kindergarten counts.

Board direction and next steps: Board members and superintendent discussed research to understand where students who left the district went and why. Superintendent Strom said WestEd will be engaged to survey or contact families who have left (approximately 1,400–1,500 high‑school-aged students have left in the recent period, staff said) to identify reasons families chose other options. Board members also suggested researching reasons families stay and amplifying positive parent testimonials. Staff noted that cohort mobility, charter/ESA uptake and demographic shifts are among the factors that affect district enrollment.

No motions were taken. Staff provided the data background and said deeper analysis and follow-up research will be completed and reported back to the board.
