Innovative strategies have been used to help older pupils support younger ones in their learning. Based on the notion that the best way to learn something is to teach it, cross-age tutoring has been used to teach pupils specific skills. Fourth year maths classes have, for example, paired up with a second year class for pupils to teach fractions. Fifth and sixth year students have paired up with younger students to learn about HIV. This cross-age tutoring in relation to HIV has also involved teachers and pupils from Buckie High School's partner school in Tanzania.
