Welcome to the NRCC

The National Registry of Certified Chemists is dedicated to certification based on education, examination, and excellence. We provide certifications for Chemical Hygiene Officers, Clinical Chemists, Clinical Chemistry Technologists, Environmental Analytical Technologists, Toxicological Chemists, and Toxicological Technologists. Various states recognize NRCC certification as a component of the licensure process for certain laboratory personnel at the Laboratory Technologist level. The Registry is a 501(c)(3) nonprofit organization incorporated in the District of Columbia.

*Effective May 1st, 2017, all NRCC exams are computer-based.*
