How do secondary STEM teachers perceive the environments in which they teach? To what degree is STEM teaching at the secondary level situated in a gendered workplace organization? Using data from the 1999-2000 Schools and Staffing Survey, we examined how men and women who were full-time secondary school teachers in STEM fields (N = 5,617) perceived the school environment, their overall job satisfaction, and intent to remain in teaching. Gender differences but also many similarities emerged. Women teachers viewed a number of student issues as serious problems. Women perceived greater cooperation among staff, but men perceived better communication with principals and recognition for a job well done. Though men had higher salaries, there were not significant gender differences in job satisfaction, and women teachers were more certain about their choice to become a teacher and planned to stay in their positions longer.
