You have to enquire individually. Pls be prepared that you may be rejected by some centres. I'd advise you to sit thro trial sessions too - to assess if the teacher is willing & able to help your child.
I've also had clients who were kept in separate rooms or left to wander thro PCF or pte kindergartens for 3 long years.
There are still vacancies in some ICPs. It depends on where you stay. Other affordable kindies include YWCA or small church-run kindies. Welcome to Centre for Enabled Living
Pls be sure to continue with therapy at Autism Assn Spore (AAS) or EI ctr; most children with autism will have difficulties coping with current P1-2 curriculum which has a lot of discussion & grp work.
you have to adopt a comprehensive search & be resolute for yr child.
