From the Florida Department of Education, Office of Independent Education & Parental Choice , McKay Scholarship Information website:

Florida’s school choice programs ensure that no child will be left behind by allowing parents to choose the best educational setting—public or private—for their child. The McKay Scholarships for Students with Disabilities Program provided over 24,000 Florida students with special needs the opportunity to attend a participating private school during the 2011-12 school year. The McKay Scholarships Program also offers parents public school choice. A parent of an eligible special needs student may choose to transfer the student to another public school.

“The school-choice issue is not about public versus private; it’s about choice. It’s about knowing what works well for my family and being able to make that choice for them.” 
— Parent of a McKay Scholarships Student
