They do that in Toronto. Basically you have a meeting with all key people, with your WISC results, since most kids are grade 3 as congregated gifted starts in 4th grade here. Each year you sit down with the teacher and develop an IEP for your kid. You can let the teacher do it themselves, sit down with the teacher (like I am doing) and/or sit down with the teacher, yourself and some specialist you want to bring in. Disabilities are seriously taken into account. The congregated gifted for our district also houses all the special ed students, legally blind, all kinds of learning disabilities. I said legally blind. Kids that can see something, but not much. So I think that they just don't do the IPRC until 3rd grade because no congregated gifted exists before then.
