DC Comprehensive Assessment System (DC CAS)
The District of Columbia Comprehensive Assessment System (DC CAS) assesses students on reading and math in grades 3-8 and 10, science in grades 5 and 8, biology in high school, and composition in grades 4, 7, and 10.
A smaller number of students with severe cognitive disabilities take the District of Columbia Comprehensive Assessment System – Alternate Assessment (DC CAS-ALT).
While DCPS oversees the administration of the test, the Office of the State Superintendent of Education (OSSE) is responsible for the overall management of the assessment for all schools in DC. For more information, please visit the OSSE website.
