Pros
Promotes autonomy. Set your own rates. You decide your hours. Freedom to select from a large range of students. Handles the billing. Provides a background check. Requires tutors to pass tests and/or prove proficiency/experience to advertise for specific subjects and grade levels. Offers package deals to students without reducing tutor's original cut. Requires an account to be set up before phone numbers are exchanged. Lesson plans, goals, and objectives are written for parents after each lesson is provided. Great way to pick up extra $ without having to substitute a full school day, plus you teach what you prepare.
Cons
It's not good for those who don't want a middle man. The original split 60/40 is absurd!! Longevity with a student or with Wyzant should be rewarded by reducing the cut to 90/10, it never gets better than 80/20. Contact with the student made by Wyzant it is not transparent for the tutor. Phone communication is blocked until an account is opened, and written communication is screened. Sometimes, a parent needs to hear a voice to make a connection!!!
