If you're still fairly new to Cambly, you may notice that your profile is tagged as "New Talent" to students. We remove the "New Talent" tag after you have accumulated enough ratings to have a reliably accurate average that we can show to students. Usually, this is after about 30 hours of tutoring.
While you are a "New Talent" tutor your rating will be fixed in the mid 4.8 range to allow your profile to get exposure to students looking for tutors. This measure will guarantee more calls from students.
Ratings from students with weak internet connections or from students who chatted for less than a minute will not be factored into your rating.
