This paper is a report on a workplace adult literacy project at Kakadu National Park in the Northern Territory of Australia. The project deals with the use and function of written text in the work of park rangers and assesses the literacy needs of park rangers and trainees. The project focuses on the uses and functions of written text in the workplace, the perceptions of park staff about written text and how the use of written text influences the work of a park ranger. The emphasis of this project is on the literacy requirements of the workplace, not on the literacy of individuals or groups of individuals working there or hoping to work there. Discussion of different groups becomes relevant, however, where needs and perceptions differ. This report focuses on what types of written text are used and are necessary in managing the park, how those texts interconnect and what types of difficulties these texts are likely to have for park rangers.
