Math Curriculum-Based Measurement (CBM) has been available for over 30 years and provides an important tool for both screening and progress monitoring students’ math skills. Although available, it is not used as widely as CBM for reading, perhaps because traditional formats such as paper and pencil are more time consuming to score. This study compared two types of math CBM scoring: Rapid and Error Analysis. Results indicated that these two methods yield scores that were highly correlated. This result is promising because the Rapid method is potentially faster and easier for teachers to use. You can locate the detailed study with the results, here.
