I had a few students who operated at a lower level, or so it appeared. Given accommodation and modifications during class tests, and building up that history of need etc. these students were entered for their GCSE’s as external candidates (thus not to effect the stats). Long story short, these students unexpectedly achieved A’s, B’s, C’s (and lower) on the day, beyond anyone’s expectations in fact. Moreover, one of these students is in her final year at University reading English! I thought ASDAN might have been a good course for them to follow, but it was sneered at, and on reflection, I’m glad it was. However, without all the facts to your case, I’d be interested in knowing what you decide too.
