Board warned small subgroup sizes can swing campus ratings under Texass closing-gaps domain

Presenter explained Domain 3 (closing gaps) evaluates subgroup outcomes — including emerging bilinguals, special education, high-mobile students and other low-performing cohorts — and said that the domains structure can make small subgroup counts consequential. "But if you have 10 students, then that, population can count for you," the Presenter said, pointing to the way subgroup reporting is constructed.

Board members discussed the fairness and practical implications of small-sample effects and the districts need to target interventions. The Presenter recommended close monitoring of where vulnerable students are placed and which teachers are responsible for interventions to reduce the risk that a small number of underperforming students would disproportionately lower a campus rating.
