AbstractA computerized question‐banking system has been developed for use in the APU national assessment in science programme. Search‐relevant information for approximately 3000 science questions is currently machine‐stored; among this information for each question is a set of key terms (up to 30 characters each). Test selection and general browse facilities are available in addition to the usual bank management routines. The power of the browse procedure has lately been dramatically increased by linking a thesaurus‐access option into the system; this allows total flexibility in the assignment of key terms to individual questions while minimizing the possibility of relevant questions being missed in a search involving key term criteria. This paper outlines the implementation and potential uses of the thesaurus‐linked browse
