Exam Dates & Locations

The Board of Laser Safety offers the exam via paper-and-pencil twice per year and also via computer-based testing centers across North America. The application process is the same for both modes of examination.


OPTION #1: Paper-and-Pencil Exams

Paper-and-Pencil exams for both CLSO and CMLSO are offered in the Spring and Fall each year. Check-in for exams begins promptly 30-minutes prior to the scheduled exam time and late admission is not permitted.

OPTION #2: Computer-Based Testing Centers

We are able to offer computer-based testing all year via appointment through our third-party partner, Prov Inc., which utilizes over 300 college and university testing centers across North America. International computer-based testing is not available at this time. Once a candidate is approved for a computer-based exam, BLS will email instructions for scheduling this exam through Prov. Some locations allow for scheduling through Prov’s online portal, while others require that the candidate call Prov to schedule. Either way, it is the candidate’s responsibility to locate a testing center that is convenient and schedule their exam within their two-year window of approval.
