Science Controlled Assessment (ISA)

The Science Controlled Assessment (ISA) is an incredibly important part of the GCSE.  For students studying the Core and Additional Science GCSEs, it makes up 25% of the available marks of the Core, and 25% of the marks for Additional.  For students studying separate sciences, there each a separate ISA for each of the Biology, Chemistry and Physics GCSEs, again with a 25% weighting.

To help students attain the highest possible ISA scores, we strongly recommend that they read the following documents.

Shown below are examples of good answers to an ISA, and average answers to an ISA.  The samples shown below are virtually identical in nature to the ISAs set every year.
