Teachers set the minimum required English level that their Students must have to book their Course. That is their choice. All screened and approved Teachers have at least a lower-intermediate English level so that there is a common language for communication: English. All Students must set their English level at sign-up so that they can only find and book Courses which are suitable for their English level. If that were not the case, both the Student and the Teacher would be very disappointed. We want your experience to be as smooth as possible.
