Comparing Private Schools and Public Schools Using Hierarchical Linear Modeling


This federal study compared NAEP reading and mathematics test scores for public and private schools. Researchers found that when selected characteristics of students and/or schools were taken into account, public school students performed as well or better in some areas. Among the student characteristics considered were gender, race/ethnicity, disability status, and identification as an English language learner. Among the school characteristics considered were school size and location, and composition of the student body and of the teaching staff.
