To track achievement increases during the pilot, Sudley used the new STAR Math computerized test developed by Advantage Learning Systems. Beginning in the 1998-1999 school year, this test, which provides the teacher with an accurate assessment of a student's math skill level, was administered every nine weeks in the computer lab. Data from STAR Math indicated that the incoming fourth grade class of 1998, which began at the 60th percentile, had within eighteen weeks climbed to the 90th percentile. By June 1999 these students were working at the 96th percentile on the normative STAR Math test. These kinds of phenomenal results are possible because Accelerated Math is a mastery system.
Students work at a level appropriate to their ability.
By working at an appropriate level, students experience success and receive the instruction they need. Until they master an objective, the program gives them unlimited practice. Achievement accelerates as students truly master the material and they end up averaging two and one-half years of growth in one year. But it gives teachers the information needed to teach effectively. The many reports available provide teachers, parents, and students with the information necessary to improve and accelerate instruction.
