After investing $1 billion in small high schools, the Gates Foundation has learned results are “mixed,” according to a study commissioned by the foundation. The study found progress in reading and language arts, but not in math.

Among the most disheartening findings of that analysis — and one the researchers said also applied to comparison schools in their study that do not receive Gates support — was the lack of rigor in teacher assignments and student work, especially in math.

“[W]e concluded that the quality of student work in all of the schools we studied is alarmingly low,” the evaluation says. “This is not surprising, however, because students cannot demonstrate high-quality work if they have not been given assignments that require deep understanding” and higher-order thinking skills.

Education director Tom Vander Ark said the Gates Foundation already is working on the problems cited in the study, emphasizing “districtwide measures intended to improve the quality of curriculum and instruction, as well as an emphasis on using proven school models.”

New schools had better results than existing schools that had been redesigned.
