Individual Women in Engineering (WiE) Programs began to emerge in US engineering schools from 1969 to 1989 to tap a new population of potential students and retain them to graduation. These early programs focused on assimilating women students into the existing engineering culture. To develop a nationally coordinated effort to increase the representation of women in the US engineering workforce and to encourage and share practices to ensure equitable opportunities, the Women in Engineering ProActive Network (WEPAN), an educational nonprofit organization, was launched in 1990. The growth and development of these efforts created a catalyzing effect on the incubation of broader national impacts, and the mission of these programs and the WEPAN organization has evolved to focus on transforming engineering cultures to be more inclusive, equitable, and diverse.
