Eight hundred and twenty-eight (828) students and 20 teachers, in sixthand seventh-grade classrooms in three states participated in the study. Students in classrooms using Achieve3000 Math showed significantly greater improvement in mathematics skills than comparable students in classrooms that did not use Achieve3000 Math. Achieve3000 Math users in sixth-grade showed 40% more growth than expected and seventhgrade Achieve3000 Math users showed 66% more growth than expected. Teachers reported that the Achieve3000 Math application is an effective tool for delivering mathematics instruction and both teachers and students were observed to use the application as prescribed.
