Click on the semester below to see workshops given during different flex periods. Flex is an obligation for most teachers. Nearly 200 opportunities consisting of face-to-face workshops, online workshops, special professional development activities and constructive observations are provided every school year. Teachers may also participate in Professional Learning Communities (PLC) and other activities for flex or for non-instructional pay. The supplemental calendars have a list of activities teachers may do to complete flex. The semester booklets are provided in May and November before the upcoming semester. The supplemental booklets are provided about two weeks after the semester begins. Flex must be completed by December 1 in the fall and May 1 in the spring.
