The CogAT is the #1 gifted identification tool but its insights were actually designed to differentiate instruction – not only for gifted students, but for every student . Each student that completes CogAT receives an Ability Profile™ – one of the most powerful data points that CogAT provides. It offers a targeted summary of a student’s overall cognitive ability, areas of strength and relative weakness, and links directly to detailed information about that student’s potential for learning and suggestions for instruction.
Ability Profiles can be individually entered and explored at CogAT, or viewed in a list with similarly-able students conveniently grouped via CogAT’s Differentiated Instruction Report, available in the CogAT Dashboard. (pictured above)
In short, the insights offered by CogAT about student ability are an important key to fully unlock and access student potential for success and achievement.

Language proficiency is a person’s ability to use language for real-world reasons naturally for many topics and reasons. For students in K-12 grades, our goal is to develop a system that supports any bilingual student to receive world language credits by demonstrating language proficiency.
World Language Proficiency Assessment (WLPE) can be used to earn Competency-based Credit, Dual Credit, and the Washington State Seal of Biliteracy.
