Suggest we provide a trainers tool kit, so start with ERT Toolkit. In later section, talks about other tools as well. My approach is to tailor to experience levels, which vary a lot, some couple of years, some newcomers. Start by giving brownie points for what they do well. Then expand on what they've missed.
Current package is too focused on repair.
Needs more focus on how to do websites well. Move away from accessibility only. Encourage people to contribute, both own web pages and the use of postings to forms. More on promoting use of curriculums in universities and other training. More on content and how to use it.
