In Florida, the debate over school vouchers was resolved (I've heard) by the creation of the McKay schoolarships in 2002. This provides state money for ESE students to attend privately owned and operated schools.
The Florida Dept of Educational Choice website says: 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 20,500 Florida students with special needs the opportunity to attend a participating private school during the 2008-09 school year. The McKay Scholarships Program also offers parents public school choice. A parent of a special needs student who is dissatisfied with the student’s current school may choose to transfer the student to another public school.
I also learned that there a vast amounts of used textbooks available through the Broward Book Repository. There's also Broward school news and such.
Other info: This McKay scholarship school, recently closed, used the following curricula:
Institute for Excellence in Writing
Videotext for Math
Create Courses for everything. Particularly liked their basic math.
Apologia for science.
When he say Time4Writing, he wished he knew about it since it's the best blend of world class video teaching of writing with interactivity and teachers that he's seen yet.
