Massachusetts Comprehensive Assessment System (MCAS) is a test taken by all public school students in the spring. The test covers subjects such as ELA, mathematics, science, and history. The test measures performance based on the Massachusetts Curriculum Framework Learning Standards.

At Grades 3–5, the math MCAS comprises multiple choice, short-answer, and open response items covering four domains equally distributed across the tests: Geometry, Measurements and Data, Number and Operations in Base Ten and Fractions, and Algebraic Thinking.

In Massachusetts, students’ test scores can be categorized into one of four levels of mastery: Level 1: Advanced, Level 2: Proficient, Level 3: Needs Improvement, and Level 4: Warning. Students scoring at Advanced and Proficient are said to have mastered the Massachusetts Learning Standards.

To determine if HMH GO Math! had an impact on learning, student MCAS mathematics test scores from the spring of 2012, prior to using the program, and the spring of 2013, after one year of usage, were obtained for Grades 3, 4, 5, and 6. These findings are presented in Figure 1.

The comparison of achievement scores revealed that at all grade levels examined, the percentage of students scoring at Proficient or higher was greater in 2013, after using GO Math! than the previous year with an average gain of over 5%.

This one-year examination of the implementation of GO Math! © 2012 at Holyoke Public School District revealed that the program was associated with increased mathematics achievement.
