Career Assessment and Diagnostic Instrument (CADI)

Administered by EEI, the Career Assessment and Diagnostic Instrument (CADI) is designed to measure your skills and abilities, vocational interests, and work style. The CADI helps employers determine what job and role you are best suited for in their company. Furthermore, the CADI outlines your professional strengths and development needs as they are related to the job for which you're applying.


CADI Test Battery

The CADI is comprised of nine specific sub-tests:

  1. Verbal/Language Skills (49 multiple-choice questions and has a 15-minute time limit)

CADI Scoring

All assessments on the CADI are scored on the basis of "right" and "wrong" except for the Work Orientation Questionnaire (WOQ) and the Campbell Interest and Skill Survey (CISS) which do not have right or wrong answers, as they are personality assessments. Furthermore, the Space Visualization Test is scored by compiling the total "right" score minus 1/5 of the total "wrong" score. 

Total scores are not combined, but are treated as individual scores which are compiled into a final report.
