Colorado Measures of Academic Success (CMAS)

The Colorado Measures of Academic Success, or CMAS, is the state summative assessment for language arts, math, science and social studies. CMAS is aligned to the state’s rigorous academic standards and designed to gauge how well students are mastering the standards and are prepared for their next grade.

CMAS English language arts (ELA) and mathematics assessment questions were originally developed as a result of a collaboration between The Colorado Department of Education and PARCC (Partnership for Assessment of Readiness for College and Careers). The Colorado Department of Education has worked with Colorado educators to develop state specific test items to appear on CMAS ELA and math assessments, starting in Spring 2019. CMAS science, social studies, and the Spanish language arts assessments were developed by a collaboration between The Colorado Department of Education, testing contractor Pearson, and Colorado educators.

The state of Colorado provides alternate assessments in the same content areas as CMAS – language arts, math, science and social studies. Visit the CoALT page for information about these alternate assessments.

Frequently Asked Questions

CMAS is aligned to the state’s rigorous academic standards and designed to gauge how well students are mastering the standards and are prepared for their next grade.  CMAS results provide a picture of student performance to schools, districts, teachers, parents, and the community. Results show how students are progressing academically, which is a key component to ensuring students are on track to graduate prepared for college and career. Teachers use CMAS results to enhance instruction in order to meet individual student needs. Schools and districts use CMAS results to make adjustments to instructional programming for the following year.

CMAS is given to students in the following grades and subjects:

  • English language arts (Grades 3-8).  A Spanish Language Arts test, known as CSLA, is given in place of the English language arts test to identified 3rd and 4th grade English language learners.
  • Mathematics (Grades 3-8)
  • Science (Grade 5, 8, 11)
  • Social Studies (Grade 4, 7, 11 in selected schools)

CMAS is primarily an online test with an option for a paper/pencil test for students with accommodations or schools with limited technology available.

CMAS measures skills and knowledge that students have been learning throughout the school year. Through classroom instruction, teachers often provide students with multiple experiences taking this type of assessment. Visit this website for practice tests and instructional resources to help teachers and students prepare for CMAS.

Results are released by the state in early Fall with schools sending home Student Performance Reports (SPRs) shortly thereafter.
