Your child's safety is as important to me as that of my own children.
As a qualified teacher I hold an enhanced disclosure CRB. However, when coaching single students it is essential that another adult, with parental responsibility is in the house and within earshot during the session: this is why I prefer to travel to your house to tutor. This protects me, and your child. Paired students, or small groups in my own home, can be left with me at your discretion, although you may stay to the tutoring session if you wish.
