dc1 is in Y3. He has been tested as a 4c a few weeks ago when they did some 'SATS' (dc1 words. I didn't know they were doing SATS in Y3??).
I did a bit of browsing on google and found that 4c is the 'expected' level for Y5 and is 'above average' but not 'exceptional' for Y3. What does it actually mean??
