For example here is a fairly comprehensive syllabus

(just picked randomly from an Internet search for syllabus examples). What I would do as part of the whole exam experience is a formal study group (there is a CI and a MCI study group but it's an open ended thing and neither are particularly active at the moment). Instead of what they currently have you could have a formal 4-6 month online training program for the theory. In many ways not unlike what I and others already do. For example for HT owners I go through the test theory over about 3-4 months prior to the test. Same deal I've offered you of course. But what I'm thinking here is that associations should have groups of say a dozen at a time and go through the exam theory task by task in a properly structured online course. They pay for it of course and it's part of the exam fee. However it's part of their training and they must do the course.
Just think what you could cover; safety and lesson plans, these could be done properly. You can also cover theory but also methods of teaching. It's massive in terms of what can be done. That's a far cry from what they have now, which may be mentoring schemes, getting a lesson from an MCI here and there, and a reading list.
Me personally I'd have it run by MCIs training to become examiners but it would have to be extremely closely monitored to stop problems like Marshall encountered. After a couple of years that course would be slick.
