"How to get an assessment for your child"
Initially, contact the team that deals with children with disabilities in your local authority to request an assessment. Alternatively, you can ask your GP, health visitor or a voluntary organisation to contact them on your behalf.
OP has said that she has NOT requested an assessment and I am guessing the 'team' of ss who are involved with the OP are not the disabilities team.
Local authorities have eligibility criteria that they use to determine whether a child is "in need" and qualifies for an assessment under the Children Act. If your local authority has decided that it will not assess your child, you can ask to be given the reasons for this decision. If you feel that your child should be assessed under the Children Act, you may wish to complain.
If you want to complain about your local authority, you should do so in writing or verbally to the complaints manager within 12 months.
Your local authority will respond within three working days to acknowledge receipt of your complaint. They will then discuss with you how long your complaint is likely to take to investigate. They must respond fully within six months unless a different time period has been discussed and agreed with you"
Complaints take a long time, requesting an assessment from the right team, quoting what the Law says you are entitled to and how you fulfil the criteria, should take 10 days.
