In Pennsylvania, the legal duty to reimburse a school district is based on the days of instruction provided by a district and payment only for the actual number of instruction days up to 180. The Department of Education presumes that, during a teacher strike, no days of instruction are being provided. However, should a school board notify the department that it intends to keep its schools open during a strike, the department--in performance of its duty--must make certain that the district's pupils are receiving an adequate education in conformity with the school code and state board regulations. This manual outlines the procedure that the Department of Education would use in fulfilling its statutory duty. (Author/JF)
