Good morning, and thank you for your question.  Although I have a specialty in working with students with a diagnosed learning difference, I am not familiar with therapeutic schools.  I'm sorry I can't be of more help.

There are many expenses directly related to college that are covered by 529 plans.  Unfortunately, college advising services is not one of those expenses.  The IRS is clear that tuition, fees, room and board, and books, computer technology or equipment required by the college attended are covered expenses.  Its not worth the tax risk to pursue paying for college advising services with 529 money.  Save the 529 for tuition and the other qualified educational expenses.

An important Step One to receiving need-based financial aid from colleges is to complete the FAFSA.  The information you report on your FAFSA is used to calculate your EFC (Expected Family Contribution). That will give you your EFC which is subtracted from the total cost of attendance (COA) of the institution.  The remaining balance is called your 'need'.  You can’t receive more need-based aid than the amount of your financial need. For instance, if your COA is $22,000 and your EFC is 12,000, your financial need is $10,000; so you aren’t eligible for more than $10,000 in need-based aid.
