As a graduate LSA with a younger brother on the autistic spectrum and an aunt with Down's Syndrome and over 10 years experience working with children and teenagers with SEN in a range of settings (starting as a volunteer when I was 15 and ranging from severe dyslexia to severe autism, GDD, Angelman's Syndrome plus a student with a severe visual impairment and one with a hearing impairment in nusery, primary and secondary schools, mainstream and SEN schools and home based programs) I find IndigoBell's comment about LSA/TAs a gross generalisation and very insulting.
This attitude just turns the whole relationship between school and parent in to us vs them with the student in the middle.
There are some truly inspirational TA/LSAs out there who have so much experience plus academic know-how and they are woefully underpaid and underappreciated.
Sorry, but a real bugbear of mine.
Get a statement, if you can. Get a statement, if you can. Get a statement, if you can. I cannot say this enough, with it come IEP targets and Annual Reviews, these are invaluable when it comes to ticking off targets and setting new ones.
I totally agree with bochead, keep smiling sweetly and asking what she will be doing to tackle these issues.
Make copious notes and if/when she starts repeating the areas your son is struggling in, nod, flip through notebook and say something like 'yes, I know, I believe we covered this in the meeting on date x but we did not agree on what to do next.'
This style of approach worked for my mum when she had the great misfortune to live in one borough, send my brother to school in another borough and attend a clinic in a third borough- this led to a lot of repeated meetings!
