Free Data Quality Exam Questions and Answers
Data Quality is part of the Certified Data Management Professional programme from DAMA International. CDMP works unlike anything else in this catalogue: everyone sits the same 100-question Data Management Fundamentals paper, and the score alone decides the tier. Sixty per cent earns Associate, seventy Practitioner and eighty Master — with the upper two also requiring two specialist exams at the same threshold, and Master additionally ten years' experience and a reviewed CV. There are no prerequisites for any CDMP exam. Each paper is 90 minutes, $311, English only and remote-proctored, and certification runs three years before annual maintenance begins.
