Experts outline adequacy study options and an evidence-based BSA estimate for Anchorage
Summary
National consultants told Alaska legislators about four adequacy-study methods (professional judgment, evidence-based, successful schools, education cost function), discussed student-count choices and school-size adjustments, and reported an ISER/Pykus high-level evidence-based BSA estimate of $13,995 for Anchorage with specified weights.
National and independent school-finance consultants told the task force the state can choose among multiple adequacy approaches and described trade-offs each method presents.
APA Consulting’s Justin Silverstein grouped studies into structural review, equity, and adequacy. He described four adequacy approaches—professional judgment panels, evidence-based modeling, successful-schools, and statistical education-cost functions—and recommended states often triangulate with two or more methods to check robustness.
Larry Pykis, who has conducted evidence-based studies in multiple states, described the evidence-based model’s five components (core staffing, dollar-per-pupil resources, add-ons for struggling students, central office functions, and state-specific cost adjustments). He said his team’s high-level 2024 analysis for Anchorage estimated a basic student allotment (BSA) of "$13,995 with a ELL weight of 0.43 or another $6,400 and a low income weight of 0.34, dollars 4701" and noted implementing the model across Alaska requires careful handling of the weighted average daily membership and the cost factor.
On class size and staffing, Pykis summarized the evidence base behind smaller K–3 classes (commonly cited around 15 pupils) as a target to improve early outcomes and make it easier for teachers to identify and address learning needs early. Speakers noted that instructional aides did not statistically substitute for certified-teacher reductions in class size in the studies referenced.
Presenters recommended that Alaska’s next study specify methodology in the RFP, prefer reproducible data sources where possible, and consider state-specific adjustments for remote- and high-cost districts rather than relying solely on a national comparable-wage index.
