The study released Tuesday found that Los Angeles Unified elementary school pupils who transferred into new schools saw their state test scores jump by 10 percentile points for English language arts and seven points for math.
High school students in new schools, however, did not see any gains.
Education professor Bruce Fuller directed the study. He speculates the difference could be in teachers. The new elementary schools attracted a cohort of young teachers with master’s degrees, while the new high schools had older staffs.
The study tracked the test scores of 21,000 students from 2002 to 2008, a period when Los Angeles Unified opened 131 new schools.
