High is a British action television series produced by Kudos for CBBC and created by Keith Brumpton.

The series follows the adventures of secondary school pupils who work as undercover spies.

The spies are led by an MI9 agent (first by Lenny Bicknall, later by Frank London) whose cover job is a school caretaker.

The team must constantly save the world from domination by a variety of villains, whilst hiding their spy identities from their teachers and peers, and completing their school work.

High was scheduled to be released on DVD in two five-episode installments by the Contender Entertainment Group, under license from the BBC.
