I have spent much of the last twenty years teaching learners of 16 plus who wanted or needed a better grade than they already had at GCSE mathematics. With very few exceptions they entered for Foundation, and achieved by their own efforts a good rate of success. But I occasionally meet learners who when they failed to achieve a C in year 11 at Foundation have been re-entered in subsequent sittings at Higher Tier. I spoke this week to the parent of a child who had got an E at Foundation in year 11, then entered three more times at Higher, and getting three Ds in the process. Can colleagues explain the rationale behind this? It can't simply be a matter of boundaries being lower at Higher, because most of the exam content then becomes inaccessible.
