This study uses a ''science pipeline'' model and cross-national data t
o examine women's participation in science education and occupations i
n seven countries. Gender stratification in later science education an
d in science occupations is found in every country examined. Young wom
en's participation in science education decreases with each stage in t
he science pipeline, but there is considerable cross-national variatio
n in the extent of gender stratification in science. Findings show gre
ater gender stratification in science occupations than in science educ
ation, suggesting factors other than training help maintain inequality
in high-status science occupations.
