I currently teach AS/A2 OCR psychology and have been in charge of the subject for 5 years. I am involved in student induction, writing the schemes of work and managing the budget as well as teaching both AS and A2. I really like the OCR syllabus and am not keen to change. Class sizes at AS are around 25 in 2 sets while at A2, the numbers reduce to 10 or less in 2 sets. I would like my school to consider introducing the subject at GCSE as an option. The students begin GCSE in year 9 now. How can I *sell* this to my headteacher, especially when school budgets are tight and it would ultimately mean employing at least one more member of staff as my colleague and I also teach another subject?
