IRS Publication 502 (page 13) states:

Special Education
You can include in medical expenses fees you pay on a doctor's recommendation for a child's tutoring by a teacher who is specially trained and qualified to work with children who have learning disabilities caused by mental or physical impairments, including nervous system disorders.

Our Orton Gillingham tutoring sessions qualify for this tax credit.

You will need to obtain a doctors note and provide that and the above link to IRS Section 502 (page 13) to the person that does your taxes.
