There are a couple colleges that have the CTP built into their degree program but that takes 4 years. And a couple regionals are set up to run the class for their new hires but there are only 4 places you can sign up for a free standing class open to anyone. There are some other TCs working on getting their program approved but it's 30 classroom hours and 10 hours in a large airplane sim so they'll never be available at smaller airports.
