It seems to me that all these levels 1c,1b,1a...5a and codes NS SS GS and ES (am assuming these are standard across English state schools) only serve to confuse parents on how well their child is doing. All born out of a paranoia to compare relative achievement between students and to muddy the waters should a parent expect good results. What's wrong with A B C D F grading or percentages or marks? Too easy to understand, too easy to compare children, too easy to monitor trends. I understand how the system works (measuring "progress") it just seems a vastly inferior system to the past. Hopefully Mr Gove has this in his sights too.
