The document outlines an agenda for a timetabling training session. The agenda includes an introduction, overview of staffing proformas and combing charts, teacher pools, clash tables and Zarraga's rule, and a question and answer session. Key tasks for heads of department are to complete staffing proformas and combing charts, consider efficient combing of year groups and staffing changes, and select effective teacher teams while following Zarraga's rule for core subjects. Successful combing does not guarantee a timetable will be produced.
