Boulder Valley School District in Colorado
Boulder Valley School District in Colorado trained a group of its faculty members to present the ZAPS ACT test-prep curriculum. Following certification from Doorway to College Foundation, these teachers instructed all juniors at three high schools in Boulder Valley School District. The study's control group included seven high schools that did not participate in the ZAPS training.
In 2010, in the control group of seven schools, performance declined slightly at -0.1 points on the ACT composite score.

Students in the ZAPS school gained 1.5 in English, 1.4 in math, 1.5 in reading, and 1.2 in science.
