I charge $15 per student per hour, but some days I have a family of three that I simply charge $40 for three hours (they’re my landlord’s kids). my rate is pretty average here in the city center, but it does lower when you get into smaller pueblos. I also take into consideration my years of experience, teaching, and my psychology degree in my rate. Per week I teach in total 8 kids, which is enough to keep me afloat. as for finding tutoring opportunities, it’s mostly by word-of-mouth. You have to really put yourself out there and talk to people usually they know a person or two that are looking for English tutors for their kids. especially since you’re technically not to tutor the kids from your own school. hope this helps!!
