Colorado Measure of Academic Success (CMAS)

The Colorado Department of Education (CDE) requires that students take the CMAS assessments annually, in grades three through eight and eleven. CMAS English Language Arts (ELA), Math, Science and Social Studies assessments were developed to measure grade level expectations, based on the Colorado Academic Standards.

Designed to be administered online, the state assessments feature a variety of interactive questions that are engaging and aligned with 21st-century teaching and learning practices. CMAS testing occurs annually in the spring. 

  • Students take English language arts and math assessments in grades three through eight.
  • Students take science assessments in grades five, eight, and 11.
  • Students take social studies assessments in grades four and seven by a rotating sample set of students.

Length of assessment:

  • English Language Arts: The unit lengths vary between 90-110 minutes depending on grade level. 
  • Mathematics: The unit length is 65 minutes. 
  • Science and Social Studies: The unit length is 60-80 minutes depending on grade level.
