I think tutor training on Schoolhouse could be more detailed and a could go deeper, not just the basics of how to tutor, but also things like adapting teaching styles, understanding how students learn differently, and using tools like AI to make tutoring more effective. For me personally, I felt that I wasn't able to directly develop skills and learn effective techniques from the training prepared on the website.

On that note, I’ve actually recently put together a site called Tutorwise.org, which has 30 lessons designed specifically for high school tutors. I'm not sure if this is useful but I hope I can help using this website.
