Washington State I-BEST

The Washington State Board for Community and Technical Colleges created the I-BEST program model and developed a funding model to enable students who qualified for basic skills instruction (based on scores on the Comprehensive Adult Student Assessment Systems [CASAS] test used by the state for basic skills students) to take college-level occupational courses that are team taught by a basic skills instructor and a professional-technical faculty member.

How I-BEST Works


CASAS provides assessments of basic and academic skills for youth and adults and curriculum tools to target instruction.

Federal and state government agencies, business and industry, community colleges, education and training providers, correctional facilities, and technical programs use CASAS.


Each year more than one million youth and adults take a CASAS test. Our tests and services promote the transition to higher education and the workforce.

Our assessments are approved by government and education agencies:

  • United States Department of Education
  • United States Department of Labor

CASAS assessments are valid and reliable for native and non-native speakers of English and assess reading, math, listening, speaking and writing. Tests can be administered on paper or online.

In addition to certifying basic skills attainment, our tests measure 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 because test items are written in the context of everyday situations that relate to their lives, their goals, and their employment.

Administrators appreciate CASAS because our 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 skills and English-language proficiency.
