For schools School FAQs What is the minimum commitment and is there a sign-up fee? There is no minimum or maximum sign-up time, and we can be very flexible to a school's needs. However, our research has shown that students need a minimum of 12 hours of tuition in order for it to have the greatest impact. As a result, our assignments are delivered in 15 one-hour blocks, so that we can make certain, allowing for absences, that the majority of tutees achieve a minimum of 12 hours of tutoring support. There is no sign-up fee or retainer. You will only be charged for tuition that has taken place with your students.
