I am an assistant head of department with 10% PPA + 1 period of Leadership time a week. As part of a new plan, we have an external agency coming in to school to run some training sessions. I have been asked to give up 1 PPA + my only Leadership time to attend the training session (to reduce the amount of cover required). To balance this, I will gain 2 additional CPD credits... We have a system where after-school/lunch CPD sessions count towards 'credits'. If you accrue 10 credits through the year, the 22nd and 23rd of July are disaggregated training days (so we don't have to be in school). If you gain more than 10 in the year, you don't get anything extra, just the knowledge of knowing you've gone above and beyond. I am highly likely to get to more than 10 (I think I'm on 7 already). What I would like to know is, can my PPA time be used for this? I know that pay & conditions says that a teacher must not be required to carry out any other duties during PPA time. Should I refuse to attend the training unless it's rescheduled? (It is on at other times when I am teaching, but obviously that would require cover). Thanks in advance.
