The latest Programme for International Student Assessment Tests (PISA) tests reveal Wales has fallen behind the rest of the UK significantly in reading, maths and science for the third time.
NUT: PISA results 'disappointing but not unexpected'
Owen Hathway, Policy Officer for NUT Wales, says today's PISA results are 'disappointing' but 'not unexpected'.
He added: "While they are a snapshot, and an important one, they probably don't accurately reflect the entire system as it is - and certainly not as it's going to be, once the reforms that were previously brought in are bedded in effectively."
