Female faculty in higher education face challenges in promotion and are more likely to leave academia than male faculty. Faculty development can play an important role in changing the institutional system within which female faculty work to help support their promotion and retention, which, in turn, can lead to more diverse and equitable systems for supporting a diverse student body. This paper identifies professional development for three groups. One, senior faculty, especially white male faculty, can be trained to be advocates and allies for female faculty by learning how to identify and intervene when discriminatory behaviors occur. Two, department chairs play a key role in creating an equitable and supportive departmental climate for all faculty. Despite their important role, department chairs often receive minimal training. Workshops on family-friendly benefits can help them support their faculty when family issues affect their ability to do their faculty jobs. Finally, promotion and tenure committees are asked to review faculty achievements and make recommendations about whether faculty members have earned promotion and/or tenure. Their recommendations are critical for faculty retention and promotion. We review several ways that gender bias can be addressed through promotion and tenure committee development activities including workshops, simulations, and interactive theater.
