The Influence of Student Sampling Plan on Standard Error for School PAAC.
Lee, Guemin; Fitzpatrick, Anne R.
The percentage of students at/above a cut point (PAAC) is one of the most common measures used for reporting school-level performance relative to a proficiency standard (L. Cronbach, N. Bradburn, and D. Horvitz, 1994). The two purposes of this study were to introduce procedures for estimating standard errors for school PAACs under a generalizability theory model and to examine the influence of different student sampling plans on the standard errors. The tests used were mathematics tests for grades 4 and 8 from a statewide assessment. More than 25,000 students took each test form within a grade. A strong relationship between the standard error for school PAAC and the number of students in a school was found. Infinite- and finite-population assumptions for students provide somewhat different standard errors when relatively small numbers of students were used for estimating school PAACs.
