有無special needs 小朋友讀緊IS

想問下有無小朋友係有special needs, 而又讀緊IS? 如ESF learning support centre or other IS, 想知情況如何及學校係咪多數要你請shadow? I'm not a rich person, but my son's therapists suggest that he better attend IS more than LS, so I would like to know more about the tuition regarding special needs support and the chance of placement.
Anybody know about ESF learning support centre? How many years to wait for a place? Thx!
