These records show in-service training classes taken by officers throughout Massachusetts through the Municipal Police Training Committee (MPTC).
Boston Police officers rarely appear in these records, most likely because they do in-service training through the Boston Police Academy, and that training is not reported to the MPTC. Therefore this data has not been incorporated into the Woke Windows database.
