The certification question is a really interesting one. We looked at a lot of other sites focused on various kinds of tutoring while building. We found that the ones that offered online "tests" for certification were producing false positives as to legitimate quality.

If I see a high schooler with certifications in 58 subjects, those certifications tend to lose their meaning. Likewise, if I have a friend with a Masters in English who taught writing at the college level fail your writing certification, it seems a little funny. That's part of the reason we took a different route.
