Nope got brown hair that's going grey.
I'm a single parent (male) brought my lad up on my own yes I'v had bad experience and yes his primary education shall we say was not good. But there's an old saying "first impressions last"
The headmistress was and still is a complete waste of time and no I cant complain because she has friends in high places i.e The LEA
SENCO Teacher never challenged the school psyc.[/QUO
Ok that clears up my troll theory.
I'm a single parent too ... put myself through Uni with five kiddies in tow after my divorce

... mine are grown up now yay, does not give me the excuse to walk about with blinkers on.
First impressions may last, no doubt, however if you continue to use that experience as a whip to beat everyone in the profession with then I really do feel sorry for you.
There is nothing at all to stop you from complaining .. except yourself .. Cc several people into your complaint.
SENCO would have worked with school psych in my experience ... but your experience appears to be different.
