If you request an evaluation from the school, they must evaluate in all areas of concern. They cannot refuse. They may not find her eligible for special ed - that is another issue. But, under IDEA (federal special ed law), the MUST evaluate in all areas of concern within about 60 days (varies by state - some states have shorter timeline).

The evaluations that you get from schools are often less diagnostic than private evaluations. But, they will give you a read on many areas of concern.
