If you have followed Step One and Step Two and your School District still has not provided an approach or program administered by a trained and certified instructor that works for your child:
Seek Advice from - NYS Special Education Quality Assurance (sometimes that can be helpful) - they can investigate but they cannot demand that your District uses a science-based program. However, it is worth reporting any districts that refuse to educate children with disabilities.

Seek legal advice from an Education Attorney - they can point-out your child's rights and put it in perspective..
