The Massachusetts Office of Public Safety and Inspections requires that builders obtain their Construction Supervisor License (CSL) from a certified provider in order for them to obtain building permits from local building departments. Preparation courses are offered and a test is required to obtain the CSL. Licenses are to be renewed every two years with proof of the required continuing education credits (CEU's).
There are many independent Construction Supervisor License preparation Course providers in Massachusetts. You can find the application and more informationfrom Mass.gov website. The Commonwealth provides this list of CSL coordinators and access to their websites.
BRAGB, your other state local chapter and the Home Builders and Remodelers Association of Massachusetts also provide CSL education. You can search for educational events here.
