Actually a 504 can involve specialist if it is for occupational therapy (ot) or physical therapy (pt), it include modifications to the enviroment testing accomidations,etc. They are suposed to be reviewed yearly. a 504 plan is part of the vocational rehibiliatation act. Many professionals belive it is best to wait to test a child not because a child is to young to be diagnossed with a learning disability (the state I teach special ed in does not test for dyslexia, but the evaluation may state carracteristics of dyslexia) but because their has to be a discrepency between the IQ (intellegence qoitent (sp?) and achievment score. Usually their is not that much discrepency in a young child, but it sometimes occurs. You could also see if the school would do a screening test to see if their is a problem. One that our student support team (it sounds similar to the ILT) is called a Kaufman Brief Intellegence test KBIT. You could ask for a schol based evaluation that you need to ask for in writting due to reading dificulties, but it will become part of your child's permentate, but seperate record. You could also pay for a private evaluation, specifically looking at dyslexia and reading issues. It is true that many students confuse b, d and p. What ever path you choose, the best help is the help you provide at home along with a positive attitude can help the most. Good luck
