Data were collected from approximately 1,600 teachers to get a statistical picture of Australian science teachers. Questionnaires provided information on sex, age, qualifications, experience, mobility, teaching conditions, lesson preparation, professional development, perceived syllabus freedom, and professional association affiliation. Results presented the average Australian science teacher as a 30-year-old male with 3.5 years tertiary education, having studied physics, chemistry, and biology to the first year level. Teaching experience was 8.5 years and mobility was rather high. Teachers spent 6.5 hours per week preparing lessons and 4 hours marking tests. They felt need for refresher courses, read science journals occasionally, belonged to the state teachers union but had joined science teachers associations in only 40 percent of the cases. (SM)
