Runner I hope the 2 weeks break gives you time to rest and re group.
As you say if the LA aren't going to issue they must inform you by week 16. However, if they are going to issue in order to stick to the timescales they must issue a draft by week 14.
As part of the needs assessment the LA must seek advice from the following:
"a) the child's parents or the young person;
b) educational advice (usually from the head teacher or principal);
c) medical advice and information from a health care professional;
d) psychological advice and information from an educational psychologist;
e) advice and information in relation to social care;
f) advice and information from any other person the local authority thinks appropriate;
g) where the child or young person is in or beyond year 9, advice and information in relation to provision to assist the child or young person in preparation for adulthood and independent living; and
h) advice and information from any person the child's parent or young person reasonably requests that the local authority seek advice from."
SEN regs 6(1)
Note h - SALT, OT (including sensory assessment) and psychiatrist &/or CP are reasonable. Be sure to ask in writing. If the LA refuse IPSEA have a model letter you can use to complain.
"Not known to the service" is not an acceptable response from social care. As you have ongoing EH involvement it shouldn't happen anyway, but you never know with LAs.
Those approached for advice must reply within 6 weeks. If assessments can't be completed within the time scales the LA must commission independent assessments.
It is vital the reports are detailed, specific and quantified as the provision will be taken from them. If they aren't ask the LA to go back to the report writers to make them so, IPSEA have a model letter for this too. If the reports are vague and woolly the EHCP will be too, and then it isn't worth the paper it's written on.
If the LA do issue you have 15 days to respond. If you think DD may need a change of placement it's a good idea to be thinking about it.
Sometimes you have to be that parent. It may be standard to CAMHS to try to get away with only 6 sessions, but those whose parents complain and push will likely be offered more. Also, if CBT is in an EHCP it should be in section F as an educational need, therefore if CAMHS won't provide it the LA must privately fund it. If DD isn't able to access CBT ask what they are going to do to help her become ready. What are DD's interests? Would something like music therapy, art therapy, animal therapy... be more likely to engage DD?
