The CMAS (Colorado Measures of Academic Success) is Colorado's statewide assessment for students in grades 3-8. CMAS tests ELA and Math at every grade from 3 through 8, with Science assessed at grades 5 and 8. Colorado also administers a Social Studies assessment on a rotating, sampled basis — making it one of the few states that tests social studies at the K-8 level at all — though it is not administered during the 2025-26 school year. Notably, the CMAS testing window is one of the shortest in the nation, spanning just three weeks in April. The assessment is aligned to Colorado Academic Standards (CAS), which are Colorado's own standards framework distinct from Common Core, and uses four performance levels with 'Met Expectations' as the proficiency target.
2026 CMAS testing window: April 6 - April 24, 2026. This is one of the shortest state testing windows in the nation — just 3 weeks. Schools must schedule all ELA, Math, and Science sessions within this compact window. Districts have limited flexibility to extend for make-up testing.
| Grade | Subjects Tested |
|---|---|
| Grade 3 | ELA and Mathematics |
| Grade 4 | ELA and Mathematics |
| Grade 5 | ELA, Mathematics, and Science |
| Grade 6 | ELA and Mathematics |
| Grade 7 | ELA and Mathematics |
| Grade 8 | ELA, Mathematics, and Science |
Colorado uses the following performance levels. 'Met Expectations' (Level 4) is the proficiency target, meaning the student has demonstrated solid mastery of Colorado Academic Standards for their grade. Unlike many states that use a mid-range level as proficiency, Colorado sets the bar at the highest of its four levels — aim for Met Expectations.
Student demonstrates minimal understanding of Colorado Academic Standards for their grade level. Significant support is needed to reach proficiency.
Student demonstrates partial understanding of Colorado Academic Standards but has notable gaps. Additional targeted instruction is recommended.
Student is nearing proficiency in Colorado Academic Standards. With continued support, the student is likely to reach the 'Met' level.
Student demonstrates grade-level mastery of Colorado Academic Standards. This is the proficiency target — the student is on track for college and career readiness.
Colorado's CMAS window runs just 3 weeks (April 6-24, 2026) — one of the shortest in the nation. Schools must fit all subjects and grade levels into this tight schedule. This means students may take multiple tests in a single week, making preparation and stamina important.
CMAS is administered online with a mix of selected-response (multiple choice), constructed-response (short answer and extended writing), and technology-enhanced items (drag-and-drop, matching, graphing). ELA includes reading passages with multi-part questions.
Unlike states that test science at every grade, Colorado assesses science only at grades 5 and 8. Science questions are aligned to CAS science standards and include earth science, life science, and physical science domains. This means grade 5 and 8 students have an additional testing session.
Colorado is one of the few states that includes social studies in its K-8 assessment program. However, the social studies CMAS is administered on a rotating basis — sampled every 3 years rather than annually. It is NOT administered in 2025-26. When given, it tests civics, geography, history, and economics.
The Colorado legislature has been actively discussing proposals to reduce overall testing time for students. Several bills have been introduced to shorten CMAS or limit the number of subjects tested, reflecting a broader national trend toward less standardized testing. As of 2026, CMAS remains in place, but the testing landscape may change in coming years. Colorado also updated its Colorado Academic Standards in recent years, particularly in science (aligning more closely with NGSS-influenced frameworks) and social studies.
Colorado has one of the shortest state testing windows in the nation — just 3 weeks in April. Most states allow 4-8 weeks. This compact schedule means schools must be highly organized and students should be prepared for back-to-back testing days.
Colorado is one of the few states that tests social studies at the K-8 level at all. The social studies CMAS rotates on a 3-year sampling cycle, covering civics, geography, history, and economics when administered.
CMAS is aligned to Colorado Academic Standards (CAS) — Colorado's own standards framework. While CAS shares similarities with Common Core in ELA and Math, Colorado maintains its own distinct standards with state-specific additions, particularly in social studies and science.
Colorado's proficiency level is called 'Met Expectations' and it is the highest of four levels — not a mid-range threshold like many states. This means Colorado sets a high bar: only students at Level 4 are considered proficient.
The Colorado legislature has been actively considering bills to reduce standardized testing time, making CMAS one of the state assessments most likely to see structural changes in the near future. Parents should stay informed about potential policy shifts.
'Met Expectations' (Level 4) is the proficiency target and the highest level on CMAS. If your child scores at Level 3 ('Approached Expectations'), they are close but not yet considered proficient. Colorado sets a high bar — focus on reaching Level 4.
The testing window is extremely short — just April 6-24, 2026. Your child may have multiple test sessions in a single week. Make sure they are well-rested, have had breakfast, and are mentally prepared for focused testing across several days.
If your child is in grade 5 or 8, they will take a Science CMAS in addition to ELA and Math. Science covers earth, life, and physical science. Don't overlook science preparation — it is a separate scored assessment.
Social studies is NOT tested in 2025-26 (it rotates every 3 years). However, if your child will be tested in a future rotation year, social studies covers civics, geography, history, and economics — topics that benefit from consistent learning even in off years.
Colorado lawmakers are debating reducing CMAS testing requirements. While the test remains in place for 2025-26, the format or scope could change in future years. Stay connected with your school district for updates on any legislative changes affecting your child's testing.
The CMAS is Colorado's standardized assessment for grades 3-8. Students are tested in Math and English/RLA every year, and Science in grades 5 and 8.
