Katherine High School is the only school offering secondary education in the region and thus is catering to the educational demands of a culturally diverse community. In seeking to meet these requirements the school has endorsed the Participation and Equity Program (PEP) of the Federal Department of Education and one highly successful and continuingly popular experimental component of this program has been the TESL (Aboriginal) unit.

This unit represents the attempts of educators and community members to construct an educational environment in which the aspirations of the Aboriginal people can be ameliorated without compromising their Aboriginality.
