I have an excellent reader in my older DD. A typical mumnet reader. 
My son is making slower progress but I'm content there is progress.
He was on a phonics intervention so would any KS1 teachers mind putting me at ease? Or on the contrary!
He's a late summer born boy Y1 on Blue book band and can access green if they are just phonics. The ones at home! School plod through the damn ORT in order.
Well within average? Below? Very below?
We read every day and I supplement hugely with library books. Of course he's very reluctant. He's a boy. Bribery works.
