We are still supplementing the academic, but we would be in any school. He was not impressed to find that they are doing humanities rather than geography, history and RE separately, misses history.
Reality is they are far better for him in terms of preparing for the real world in terms of social interaction etc. than we ever could alone. The time spent on this is why there are gaps in academic, but in truth the stuff he's covering is as good as I here a lot saying in mainstream education.
The school works the same way we do, considering ASD as something to use the strengths of and work through the weaknesses, not just make excuses and expect the world to deal with the result. Not the easy option by any means so we get days that are either great or terrible dependant on what has been done.
