How much feedback do you get from your SEN child's mainstream school? My primary DC has some 121 with a TA (no EHCP) due to being very slow to develop literacy. But we NEVER get feedback on what is happening / progress. We do have regular parent teacher meetings, but the teacher isn't very clued up on what the TA thinks / does so we're more or less in the dark.
The few times I've seen the TA in passing, she's very knowledgeable. But we never get access to that info or what our DC is doing.
