This article summarises the practical requirements for new science A-levels in biology, chemistry and physics for first teaching from September 2015. It discusses the background to how the new approach was reached and how OCR has seen this taking shape in our assessment models. The opportunities presented by this new approach to practical assessment could, we feel, add value to practical teaching and learning within schools and colleges compared with current controlled assessment regimes. The importance and central nature of practical work is undisputed; this article focuses on the potential opportunities of a more holistic, teacher-led approach to development of essential practical skills during A-level science courses.
