I think it really depends on the area. We live on a fairly 'rough' council estate (it is actually a lovely place to live, just poor) and had a CME officer drop round during the summer holidays before DD1 was of compulsory school age.
It was very obvious that she was thinking 'feckless parents not bothering to send their DC to school'. However, the person I dealt with at the LEA was perfectly fine with us.
