The paper describes a national survey of biology teachers visiting Field Studies Council (FSC) centres in England and Wales. It provides data on levels of biology fieldwork at ages 11-16 (Years 7-11), and factors affecting A-level biology fieldwork provision at ages 16-19 (Years 12 and 13). The results are compared with similar data from geography teachers. Clear differences are demonstrated: in levels of lower-secondary provision; in teachers' perception of factors affecting fieldwork provision; and in the periodicity and timing of fieldwork. Recommendations are made towards improving the status and level of provision of A-level biology fieldwork. (Contains 4 tables and 2 figures.)
