I am Head of School in a SEBD Independent school. We have had a reshuffle of staff and our supply science teacher has left leaving me with a bit of a mess. The year 10/11 group has had to be combined to allow for expansion in the primary department. The year 11s have been following (loosely) the AQA entry level syllabus and have completed and entered three units. The year 10s have done even less. The pre-ofsted we had a couple of weeks ago suggested that the entry level was a waste of time as the points that it is worth are equal to the points gained from a level 4 Sats at KS2 and suggested I pushed them to work on GCSE accreditation. This is all well and good but I am qualified at KS2 and experienced to KS3, I have never taught at GCSE level and do not wish to teach science in a lab with unfamiliar chemicals etc. I have tentatively looked at the Edexcel specification and could possibly manage the biology sections. Would OCR or AQA have easier specs for me to follow. These kids are not the best students and have diverse learning needs. Please could someone advise me on what would be the best course of action. I am taking on the group when school returns.
