“We found that students attending schools with lower building quality and those attending schools with high student mobility had lower test scores,” says Evans.
They also found that when these two risk factors were combined, it was particularly damaging to academic achievement. These negative effects on test scores occurred independently of socioeconomic and racial composition of the school.
The study is the first to demonstrate the interaction between the condition of school facilities and student mobility.”
