Science Academic Standards

Science is facts; just as houses are made of stone, so is science made of facts; but a pile of stones is not a house, and a collection of facts is not necessarily science.” --Jules Henri Poincaré (1854-1912) French mathematician.

High expectations in education are essential for the U.S. to continue as a world leader in the 21st century. In order to be successful in postsecondary education, the workforce, and in life, students need a rigorous, age-appropriate set of standards that include finding and gathering information, critical thinking, and reasoning skills to evaluate information, and use information in social and cultural contexts. Students must learn to comprehend and process information, analyze and draw conclusions, and apply the results to everyday life. (Read more about Colorado's Science Standards.)

Implementation Timeline Extended for the 2020 Colorado Academic Standards for Science 

Recently CDE solicited feedback on the option to extend the implementation timeline only for the science standards.  As a result, full implementation of the science standards will take place in the 2021-22 school year. The Colorado Measures of Academic Success (CMAS) science assessments will transition to covering the 2020 CAS in science no sooner than the full implementation of the 2020 science CAS.
