q2 · i? · associational · r?
Seasonal growth analysis of the 4,228-student cohort, assessed up to three times per year, found that across-year comparisons show ever-SPED students' summer learning losses exceeded those of never-SPED students in every summer of the kindergarten-to-4th-grade span.
"However, ever-SPED students lost more learning during every summer than never-SPED students"
