All substitute requests must be entered in AESOP. If the absence is for fewer than 3 class periods, teachers should mark "no sub required" and work with their division resource person to provide for an internal substitute. If a teacher teaches few than 5 classes, s/he should include the periods taught in the notes to the substitute in AESOP. It is the teacher’s responsibility to leave class lists, seating charts and appropriate lesson plans for the substitute. For additional information, click here.
