Who are the teachers?

The teachers are all specialists in their respective fields. Teachers on this site come from a variety of backgrounds. For example, we have teachers who are graduates of Ivy League institutions such as Columbia University. All teachers must be approved before they are allowed to post content on the site. Any teachers posting course content on the site are, thus, very professional and regarded highly.

Is there a code of conduct for teachers?

Yes, you can find it here. (coming soon) As a general rule of thumb however, try to keep the following in mind during your time as an online teacher at Prep 21:

  • Answer student questions in a timely manner.
  • Try to keep your content new and up-to-date.
  • Only upload content for which you have the copyright to.
  • Post questions in the forum when you need help.
  • Be courteous and supportive!
