Recognizing the need for professional development related to preparation for faculty positions, Northeastern University has sponsored the New England Future Faculty Workshop (FFW) since 2009. The participants were later-stage doctoral students and postdoctoral scholars who were predominantly women and from racial groups underrepresented in STEM fields. Applicants were accepted to the workshop after they submitted draft faculty job application materials. The workshops included sessions on institutional fit, research, teaching and diversity statements, interviewing and negotiation, time management, and navigating a faculty position. Participants also received detailed feedback on their application materials in a discussion session with a faculty member who had served on a faculty search committee. Based on post-workshop survey responses, participants found the workshop valuable and reported that the workshop enhanced their understanding of the process of applying for a faculty position. Of the survey respondents, 94% indicated they would recommend the workshop. After the workshop, participants reported increased preparedness and confidence to move forward with the faculty job application process. As of June 2023, 435 of the 709 participants had moved into new jobs. Two hundred and eighty-two (65%) of those jobs were in academia, with the majority, 220 (78%), in faculty positions at primarily R1 institutions. The percentages of tenured and tenure-track faculty from groups underrepresented in academia who attended the workshop were up to three times greater than reports of national tenured and tenure-track faculty. FFW organizers will continue to use participant feedback and Higher Education trends to maintain and strengthen this successful program.
