Birkman assessment is available in more than 23 languages, and has been used by more than 400 government agencies, organizations and private companies in more than 15 different sectors around the world.

Validity studies have been conducted comparing to other assessments to prove the efficacy of Birkman.
Birkman scales have test-retest reliability averaging 0.85 and internal consistency reliability averaging 0.80
Birkman system checks and validates the beneficiaries' response, and if the beneficiary's answers are not confirmed as accurate, its reports are not issued unless approved by Birkman's Quality Department. Completing a one-time Birkman assessment does not require it to be returned again, so we call it “one-time investment.”
