Test Scoring Information

Test Scoring

CCO written examinations are criterion-referenced examinations; i.e., the passing score is set beforehand, and candidate performance on the examination is not compared to the performance of others taking the examination. In a criterion-referenced examination, a candidate must obtain a score equal to or higher than a predetermined passing score to pass the test. The passing scores represent absolute standards and are determined by panels of CCO content experts using a psychometrically accepted standard-setting methodology.

Score Reporting

Candidates receive preliminary exam results immediately following testing. Results are also available in the myCCO Portal and are emailed.

Retaking the Examination(s)

Candidates who fail an examination(s) may retake the examination(s); they must reapply and pay all corresponding retest fees. Written exam retest candidates are required to wait a minimum of four weeks before retesting on the same exam.
