Many of these tutors work independently, meaning that they enter into verbal or written contracts directly with parents, carers or adult students. In this situation, it is the responsibility of the parent, carer or adult student to check the suitability of the tutor (please see our Safety Advice for further information). Independent private tutors will often advertise their services, for example on this website. Other tutors are provided through private tuition agencies. Tuition agencies charge parents, carers and adult students a fee for finding them a tutor. This can be an introduction fee, commission for the duration of the tutoring contract, or both.
