Can I deduct tuition for dyslexia school?

 Special schooling, for the disabled, can be considered medical expenses.

To be eligible for the tuition credits or tuition & fees deduction, the course must be taken at "an eligible institution". The school should be able to tell you if it is an eligible educational institution. In general, an eligible educational institution is an accredited college, university, vocational school, or other postsecondary educational institution, including accredited, public, nonprofit, and proprietary (privately-owned, profit-making) postsecondary institutions. Additionally, in order to be an eligible educational institution, the school must be eligible to participate in a student aid program administered by the Department of Education. If they issue a 1098-T they are probably an eligible institution.

Maybe.  "Dyslexia school" may not need to be an "eligible institution".  It depends on the nature of the deduction.   It would need to be an eligible, degree granting institution to be deductible as an education expense, but dyslexia is a recognized medical condition, therefore it may be deductible as a medical expense.  

It is often the case in full-time schools that specialize in dyslexia and other learning disabilities that only a portion of the tuitin and fees paid are qualified medical expenses.  Many of these schools are able to help break it down for you.  If you do not attend a school that can do this keep a few things in mind when determining the potentially deductible portion of your expense:

• the expense must be to treat or correct the medical condition (it can't be "general welfare" or "general education" in this case)
• it helps if the treatment is specifically prescribed by a medical professional, but this isn't always necessary
• keep excellent records of the itemized costs of treatment and be prepared to demonstrate how they treat the condition and wouldn't be considered general education expense
• you will need to itemize deductions and then only the amount of expense that exceeds 7.5% of the Adjusted Gross Income (AGI) is deductible (since these schools can be quite expensive, these along with other deductible expenses for a family often easily reach this threshhold)
