Construction of all one- and two-family dwellings and all buildings containing less than 35,000 cubic feet of enclosed space must take place under the supervision of a person licensed by the Massachusetts Board of Building Regulations and Standards (BBRS). The BBRS has contracted with Prometric Inc. to conduct its Construction
Supervisor License (CSL) examinations, including Specialty Construction Supervisor Licenses. Construction Supervisor exams, or CSL tests, are intended to test a candidate’s knowledge of building code and general construction practices. There is a process to register for and take the CSL exams. Passing the exam results in a Construction Supervisor License or CSL.
