Your question is the equivalent of asking why was there initially only one low cost airline. Quite simply because the others either did not understand that it was possible, or (in some cases) did not want it to become possible. But once the customers recognised the value of the idea, a larger number of suppliers took it up.
For many years only two schools have used the scheme. Both are colleges of further/higher education. It was only when we investigated the subject that it became apparent to us that all FTOs could use it. We are simply the first. Provided students are prepared to insist on benefiting from the grant money, all FTOs will eventually join. But if students swallow the low cost = low quality line, the grant money will stay in the pockets of the government and students will continue to pay more than they need to.
This scheme can only benefit students. But it involves effort on the part of the FTOs to register. So some will be unwilling to take it up unless student pressure makes them do so.
