About CASAS – Comprehensive Adult Student Assessment Systems

CASAS is a nonprofit organization that provides assessments of basic skills for youth and adults and curricular tools to target instruction. CASAS is used by federal and state government agencies, business and industry, community colleges, education and training providers, correctional facilities, and technical programs.


Each year basic skills tests developed by CASAS are administered to more than a million youth and adults in more than 40 states and territories, and in multiple countries. CASAS products and services certify language and basic skills proficiency and promote the transition to higher education and the workforce.

CASAS is a longstanding and exemplary organization whose assessments are approved and validated by worldwide government and education agencies including:

  • United States Department of Education,
  • United States Department of Labor,
  • Singapore Workforce Development Agency, and
  • El Salvador Technical Colleges.

CASAS assessments are valid and reliable for both native and non-native speakers of English and assess the modalities of reading, math, listening, speaking and writing. CASAS tests can be administered on paper, by computer, and via the Internet. In addition to certifying basic skills attainment, CASAS measures learner progress on a standardized scale that ranges from the lowest literacy skills to high school exit and transition to postsecondary education and training.

Test-takers appreciate CASAS assessments because test items are written in the context of everyday situations related to life and work.

Administrators appreciate CASAS because the standardized tests are able to track longitudinal progress and to certify attainment of benchmark levels of proficiency.

Employers appreciate CASAS because test results provide an international standardized benchmark system for certifying work-related basic skills and English-language proficiency.
