TEACHING LOADS AND ASSIGNMENTS A. The normal teaching load in the senior high school will consist of an average of five (5) daily teaching periods and one (1) period of preparation, or the equivalent thereof. The normal teaching load at the middle school will consist of an average of five (5) daily teaching periods and one (1) period of preparation for core curriculum teachers. Related academics teachers at the middle school will teach five (5) periods per day on average with one (1) period of preparation. The term “preparation period” shall be construed to include the use of this period for purposes other than preparation that would be considered reasonable professional responsibilities or for purposes other than preparation when emergencies arise. The Association agrees that the purpose of non-teaching time (other than lunch periods) is to permit the teacher to have time during the school day for planning, conferences, preparations for teaching and related teaching functions and obligations concerned with the actual teaching assignment. The normal teaching load in the elementary schools for classroom and elementary teaching specialists will be approximately 26.5 hours of classroom duties weekly, or the equivalent thereof. Elementary teachers may use for preparation all the time during which their classes are receiving instruction from teaching specialists in the areas of elementary art, music, and physical education, and during the time of the 20 minute recess period when the students are under the direct supervision of hired playground aides. In addition, one-half (1/2) hour of the delayed start professional development days will be reserved for personal planning. Consistent with the above requirements, the Board shall determine the equivalence for employees in the bargaining unit who are assigned to non-classroom duties, such as librarians, guidance counselors, and itinerant personnel, etc. Travel time for all itinerant personnel shall count as contact time. The class size of an elementary teaching specialist will not exceed that of the elementary classroom teacher whose class they have for instruction (i.e., they will not have more than one teacher’s class during an instruction period). Exceptions will be made to accommodate students from self-contained special education classrooms. Department chairmen shall be appointed by the Administration and have such released time for their duties as the Administration deems necessary.
