I think that there should be some sort of forum that is ran by staff. This forum would allow trial staff members and users who want to become staff to train their moderation skills and strategies. This forum would also allow for a better selection of future staff members.

What this forum is/would be:

It would be a board/forum with multiple threads in it. Then staff members would award a Local Moderator position to the person who requires/wants training. Then a 'moderation test' would occur.

The moderation test would include multiple waves of staff/bots posting threads and posts within the threads. The threads/posts could be filled with malicious things in need of fixing that are hidden by good/quality posts. If the moderator in training fails to correctly moderate these problems they would receive minus points to their final score.

Maybe there isn't enough staff to handle all of this. But a way around this is to have one or two staff members with alternate accounts running the board and posting. Another way to fix this is to have the test cost TC. This would only apply to regular non-staff members of the community. Trial staff members would take the test for free. This would limit the amount of tests/amount of people that want to take the test. Only people that are determined to improve their moderation skills would take the test.
