The CDA Exam is a 60-question, computer-based assessment administered at Prometric testing centers nationwide. You have 95 minutes to complete it. Questions are scenario-based, testing your ability to apply ECE competencies in real classroom situations rather than recall definitions.
The exam covers all 8 CDA subject areas proportionally. A passing score requires answering at least 36 of 60 questions correctly (60%). If you fail, you may retake after 1 year — making thorough preparation essential.
