General Assessment Information

The Colorado State Assessment System is designed to measure Colorado student’s mastery of the Colorado’s academic content standards. In December of 2009 Colorado adopted revised academic content standards progressing from early school readiness to postsecondary competencies reflective of both workforce readiness and 21st century skills.

In 2012 Colorado implemented the Transitional Colorado Assessment Program (TCAP) to reflect changes in the state adopted academic content standards and to provide information to teachers as they began incorporating the revised content standards in their daily instruction. In 2012 Colorado became a governing member of the Partnership for Assessment of Readiness for College and Careers (PARCC) consortia which is currently developing new assessments in English language arts and mathematics for grades 3-8 and high school. The PARCC assessments are scheduled for implementation in 2014-15.

New general and alternate assessments for science and social studies were field tested in 2013 and are scheduled for implementation in 2014.

The attainment of English proficiency by English Language Learner’s (ELL) is measured annually by an English Language Proficiency (ELP) assessment. In the 2012-13 school year Colorado implemented the ACCESS for ELLs® ELP assessment developed by the World-Class Instructional Design and Assessment (WIDA) consortium.

The CO ACT assessment is designed to measure students' preparedness for postsecondary educational opportunities and is administered to 11th grade students in April and May. Because the CO ACT is equivalent to all other ACT assessments the results can be submitted for college entrance by the student to their college or university of choice.
