NCCER exams (Module examinations) correspond directly to a given module in the curriculum, and are administered at the end of each module to determine proficiency of the topics covered. Passing a curriculum module or level test does not result in an industry certification, but successful completions are recorded in NCCER's Registry.

NCCER assessments are part of its National Craft Assessment and Certification Program (NCACP), in which a complete series of journey-level written assessments are available. These assessments evaluate the comprehensive knowledge of an individual in a specific craft area. All individuals wanting to take an NCCER journey-level assessment should have a minimum of four years of industry experience or training to journey/technician level in that field. You must pass the NCCER written assessment and the corresponding Performance Verification (PV) to earn a "Certified" credential.
