Can CIHs become re-certified if they lose their certification?
A person who failed to maintain their certification may be re-certified by passing the Comprehensive Practice examination. It is Board policy that an individual’s original certification number will not be reassigned. To re-certify by examination, a person previously certified in the Comprehensive Practice is required to submit a written request attesting to current industrial hygiene practice and a $75.00 re-application fee. CIHs certified in an Aspect must qualify to take the Comprehensive Practice examination by providing a Reapplication form and a Professional Reference Questionnaire form from supervisors covering the latest two years of employment and a re-application fee of $75.00. The examination fee for either exam is $350.00.
