Subgroup Size--Confidentially and Statistical Reliability. Quick Turn Around (QTA).
Markowitz, Joy
The reauthorized Elementary and Secondary Education Act, commonly refereed to as the No Child Left Behind Act (NCLB), require states to demonstrate that all public schools make adequate yearly progress (AYP) with respect to student academic achievement. The measurement unit is schools and the following four subgroups within each school: economically disadvantaged students; students from major racial and ethnic groups; students with disabilities; and students with limited English proficiency. If the number of students in a subgroup is of a size that would reveal the identity of the students or the subgroup is not of sufficient size to yield statistically reliable results, the AYP of that subgroup need not be reported separately. This report summarizes information from 37 state education agencies (SEAs) on the minimum subgroup size for reporting test results to guarantee confidentiality and yield statistically reliable information. Results indicate at least 30 SEAs have policy or practice in place related to the minimum number of students required in a subgroup to conceal individual student identity. In comparison, only 14 responding SEAs have policy or practice related to the minimum number to yield statistically reliable results for reporting and 12 for measuring AYP. (Author/CR)
