A new intervention report from the What Works Clearinghouse (WWC) reviews the research on ACT and SAT test preparation and coaching programmes, which are designed to improve students’ scores on these college entrance exams.
The WWC reviewed 26 eligible studies on the topic, of which six met WWC research standards. Of these, three studies showed statistically significant positive effects for general academic achievement, and three showed indeterminate effects.
The WWC aggregated the reported effects from each study to create an assessment of effectiveness. Using this method, they concluded that ACT and SAT test preparation programmes have positive effects on general academic achievement for high school students.
