Los Angeles Unified built 131 new schools in the last decade to end overcrowding. Elementary students who moved into new schools made strong achievement gains equal to another 35 days of schooling, according to a Berkeley study. But high school students improved only a bit in English Language Arts and not at all in math when they moved from a crowded building to a new facility.
“How new elementary schools are lifting achievement remains somewhat of a mystery,” said William Welsh, the UC Berkeley Ph.D. student who carried out the statistical analysis. “New schools in LA Unified are much smaller than older schools, perhaps offering warmer, personal settings that are more conducive to kids’ learning.”
. . . Achievement gains were even stronger for elementary students escaping the most severely overcrowded schools and landing at a new campus – gains equivalent to lengthening the school year by up to 65 days, said the report.
LA Unified spent just under $15,000 per pupil, on average, for the new schools. “We found no evidence suggesting that more expensive school facilities yield stronger achievement,” Berkeley Professor Bruce Fuller said.
