Hi--This isn't always easy to find out, especially as the DOE handbook for high schools has the same pat line of providing all services at all high schools. I can't imagine, for instance, that Stuy or HSMSE, no matter how lovely the school, is ready to provide a single child with a CTT class. Still, the DOE is signalling its willingness to honor the American with Disabilities Act this year and perhaps extend more services into schools which traditionally have shunned them (thereby not following the ADA requirement of providing services for kids and providing "appropriate" educations for all kids). If you are a huge pioneer and your child is too, you cna take the DOE at its word and just apply away! If however, you want to see what schools have a history of providing CTT insideschools.org lists the historical services, still, at the bottom of the page for each school. Just go to the school's page and scroll down.
