Vmath Powerfully Impacts
Performance Across Grade Levels
An effect size between .4 and .6 is considered moderate, and .8 is considered large. Across grade levels, Vmath students posted gains between .75 and 1.3, meaning these students showed tremendous improvement from the beginning to the end of the year on their pre- and post-test scores.

Two Years Growth in One Year

Sixth graders in Aliceville Middle School in Alabama went from a 5.2 grade level equivalent to 7.4 during the course of the year based on their STAR Math Assessment.

For more detail on these gains and to see additional Vmath results, read A Summary of the Effectiveness of Vmath.


My 5th graders LOVE, LOVE, LOVE Vmath! They were literally jumping up and down excited about starting a new workbook and getting to keep the other one that we just finished. They are doing so well! I am seeing 'light bulb moments' daily! One of the girls that really struggles in math made a 100/A+ on her post-test from Module 1 yesterday! It is so exciting.
