How can we assess GPC and oral blending knowledge with a non-verbal child?

Use images and get them to point to the correct image from a selection.

For oral blending words and GPCs, just use the grapheme cards.

Use the SEND Phase 2 assessment as this allows you to measure smaller steps of progress. For example, whether they can recognise the mnemonic, even if they can't recognise the GPC yet.

Everything you need to run the SEND assessments, you can find here.
