Colorado Measures of Academic Success (CMAS)
Science and Social Studies

CMAS assessments for grades 4, 7 in SS and grades 5, 8 in Science was given live online for the first time in spring of 2014. Science and Social Studies are also given to 11th graders. CMAS Science and Social Studies is the Colorado developed SS and Science assessment.


The Colorado Measures of Academic Success (CMAS): Science and Social Studies is Colorado's standards-based assessment designed to measure the Colorado Academic Standards (CAS) in the content areas of science and social studies.

A very small number of students with significant cognitive disabilities may take the Colorado Alternate Assessment (CoAlt) based on the Extended Evidence Outcomes (EEOs) of the CAS.

The CMAS and CoAlt: Science and Social Studies assessments are collaboratively developed by the Colorado Department of Education, the Colorado educator community, and Colorado's science and social studies assessment contractor, Pearson. The data should be used to keep abreast of individual student, school, and district progress toward attaining higher student achievement levels.
