Classification accuracy of the screening cut scores is lower for Grades K-2 than Grades 3-8, attributed to a 12-36 month lapse between MAP Growth and criterion measures¶

q3 i? Classification accuracy statistics are lower for Grades K-2 compared to Grades 3-8, which the article attributes to the longer time lapse between the criterion measure and MAP Growth for Grades K-2. → He 2021

Results across both samples show weaker K-2 accuracy; for example, Kindergarten reading AUC lower bounds were 0.75 (primary) and 0.73 (secondary). The article attributes this to K-2 MAP Growth scores being taken "12–36 months prior" to the Grade 3 state test used as criterion.

"the classification accuracy statistics are lower for Grades K–2 compared to Grades 3–8, although this can be attributed to the longer time lapse between the criterion measure and MAP Growth for Grades K–2 (i.e., students typically do not start taking the state summative assessment until Grade 3, so the MAP Growth scores for Grades K–2 are from 12–36 months prior)"
