While managing the intercollegiate athletic development office is critical to contributions generation, the nearly 40 years of research modeling intercollegiate athletic fundraising emphasized limited factors external to this department. Both theoretical and statistical justification warrants a broader scope in contemporary factor identification. With a resource-based view as the theoretical foundation, a list of 43 variables both internal and external to the intercollegiate athletic development office was generated through an extensive literature review and semistructured interviews with athletic and nonathletic fundraising professionals. Based on the factors identified, random and fixed effects regression models were developed via test statistic model reduction across a 5-year panel (FY2011–FY2015). Ninety-three schools were included, representing 73% of the Football Bowl Subdivision (FBS) membership (85% of public FBS institutions). The results highlight the role of both internal and external factors in explaining intercollegiate athletic fundraising procurement.
