The National Center for Parents with Disabilities and Their Families, or Through the Looking Glass, awards scholarships each year to high school seniors and college students who have at least one disabled parent. Selection is based on scholastic achievement, community service, a recommendation letter and a student essay. http://lookingglass.org/scholarships/TLG_Scholarship_Form.pdf

The children of disabled veterans can apply for a grant under the GI Bill. The Dependents' Educational Assistance Program (DEA) provides a monthly allowance for the children of veterans with permanent and total service-connected disabilities. DEA grants are usually awarded to college students between the ages of 18 and 26. The amounts vary, depending on whether the student is enrolled full-time or part-time. http://www.gibill.va.gov/pamphlets/CH35/CH35_Pamphlet_General.htm
Many states have enacted laws that provide financial aid to the children of disabled veterans. Some states provide up to five years of tuition-free education at state-sponsored colleges and universities. http://www.military.com/money-for-school/state-veteran-benefits
