She plans the lessons that are PPA times, NQT times and Management times - basically the regular timetabled sessions. The other times (cover for teacher performance management, courses) are planned for by the teacher and left for her. It makes sense that the teachers leave her the plans for the sessions that they are normally there for seeing as they would have taught the previous session. However she plans for all of her timetabled PPA covers, NQT times and Management times. Her PPA is to plan these sessions.
