The efficacy of stipends in drawing new teachers to participate in math teachers' circle and encouraging previous participants to attend meetings regularly was investigated in this study. A kickoff event was planned to start the year with more fanfare than usual. Stipends were advertised for teachers who attended at least three meetings. Matched pairs data analysis and survey results were used to investigate the observed increase in attendance.
