Written exams: Confirmation letters, instructions, directions and test site contact information are mailed 2 weeks prior to the exam. If you would prefer to take the written exams at a location near you or in your home laboratory, please contact us to learn about exam hosting requirements.
Practical exams: Confirmation letters with molds, instructions, directions & test site contact information are sent out 4 weeks prior to the exam.
NOTE: Applications received after the application deadline are subject to a late fee. Please call the NBC headquarters to see if you are too late for exam registration. Exam dates are tentative until 30 days prior to the exam. For this reason we recommend that you do not make travel arrangements until you received your exam confirmation letter.
