"Keystone is a professional organisation that is working in the best interests of the student first and foremost, with employed tutors who have good experience and thorough knowledge of their subject." - Parent
- Tutoring should be used judiciously. Families place a lot of trust in us when they ask how much tutoring their child needs. We believe that a tutor should not upset the balance in a child's life between work and play.
- Tutors should be a victim of their own success. Successful tutors help their pupils to become academically self-reliant.
- Tutoring should be transparent. When it's appropriate, we encourage tutors to coordinate their work with their pupils' schoolteachers and other educational professionals.
- Tutoring should not be the preserve of the elite. Keystone has a considered charitable scheme to provide tutoring to families who would not otherwise be able to afford it.
