This document provides information about license renewal requirements for teachers in Massachusetts. It discusses that professional licenses for both academic and vocational teachers must be renewed every five years. Teachers must complete 150 professional development points (PDPs) during each renewal cycle to maintain an active license. If a license expires and becomes inactive, teachers have different windows of time to complete PDPs and renew their license depending on their employment status. The document also outlines the PDP allocation requirements and approved professional development activities teachers can engage in to accrue points.
