Gifted education does NOT fall under IDEA. If you suspected that your child had a disability, then the school would be obliged under IDEA to evaluate to see whether or not your child had a disability that affected educational performance, and to determine whether special education and related services were required for your child. Such evaluation typically includes IQ and achievement testing. There is, however, no Federal mandate to identify and serve gifted children. Some states have laws that include gifted education under special education, and in some (but not all) of those states, the school is required to test if the parent requests it.
