What option do Harry's parents have if they disagree with the school's evaluation results?

The correct option is to ask for an independent evaluation for Harry. When parents disagree with the school's evaluation results, they have the right to request an independent educational evaluation (IEE). This process allows parents to seek an evaluation from a qualified professional who is not affiliated with the school district. The results from this independent assessment contribute to decisions regarding the child’s eligibility for special education services and the development of an appropriate education plan.

Choosing to suggest an alternative evaluation process for Harry may not be the formal channel available under special education law; parents do not have the authority to dictate specific procedures that the school must follow. Delaying the evaluation process for a year is also generally not an option as the school is required to adhere to timelines established by law for evaluations and services. Lastly, parents cannot select the specific school personnel involved in a reevaluation, as this responsibility rests with the school district. Therefore, advocating for an independent evaluation is the most appropriate and empowered course of action for parents in this situation.
