Traditionally in England, exam results in General Certificates of Secondary Education (GCSEs) (and before them O levels) and A levels have been reported as letter grades, with A (or A*) as the top grade, then B, C etc. The reforms gave the opportunity to revisit the arguments for different formats of reporting, and Cambridge Assessment contributed to the early debates with a short paper recommending the use of longer numerical scales (Bramley, 2013). The purpose of this study was to explore in more depth the arguments for and against different reporting scales.
