Usualy, but I don't know SC laws, there is a further screening as well. This may have been a preliminary refferal, there is usualy a subsequent and further assesment prior to admission to special education. So it is likely (at least in Illinois) that they would have been bounced back by the MSW and the school psychologist, especialy since there is a standard of criteria for special ed (the big one being that your academic expression does not match your tested ability or that you have an IQ below 70).
This is the case. My son would have been admitted to the special needs school and evaluated. He almost certainly would be sent back, but his "official records" would show that he had been in special needs school and it could have created problems down the road getting admitted to advanced classes in regular school (his eventual evaluation showed he has a fairly high IQ). His teachers though they were doing a good thing by evaluating him so high. There thinking was that he needed to be in special needs and if they honestly evaluated him he might be rejected. Oh well, you not is paved with good intentions.
