Are you able to show progress from your methods?

Dave, no-one can do this.

So taking a child who can't read to a child who can read. Taking someone, from when they can't speak a foreign language to one who can speak a foreign language? No-one can do this?

Of course you can measure progress in education. Whatever method is used to reach that goal and however long a period, it is possible to measure progress.

It isn't the be all and end all. But don't tell me it isn't possible.
