Yes! Tutors manage their own rates and can change them at any time. Some tutors set specific rates for group or online lessons, traveling outside of their normal radius, or because a student requests a discount. Tutors can opt to include this information on their profiles, but are not required to do so. You should feel free to message a tutor with any questions you might have about their rates.
If a tutor agrees to change their hourly rate, you will receive an email notifying of you of the change. In the event of an increase, you must agree to any changes a tutor makes to their hourly rate before a lesson occurs, which can be done easily through a link included in the email message.
