Organizational climate is the shared perception of and the meaning attached to the policies, practices, and procedures employees experience. University faculty can assess their organizational mentoring climate (OMC) using recently published, reliable, and valid OMC importance (OMCI) and availability (OMCA) scales. Factors affecting the OMC's importance and availability are, however, not known. By studying these factors, organizational leaders can determine whether and how to change the OMC to improve faculty mentoring outcomes. In this cross-sectional study, 300 faculty from the University of New Mexico (Main, Health Sciences Center [HSC] and branch campuses) and Arizona State University (a non-HSC campus) completed the online OMCI and OMCA scales, each with three subscales: Organizational Expectations, Mentor-Mentee Relationships, and Resources. OMCI scale items were rated from very unimportant (1) to very important (5); and, for OMCA, -1 (no), 0 (don't know), 1 (yes). The study used linear regression analysis after normalizing the scales to M=0 and SD=1. Although not explicitly targeted for recruitment, the respondents were predominantly women, non-Hispanic White, senior, tenure-track faculty members who were neither providing mentoring nor receiving mentoring. In the multivariable models, women faculty attached greater importance to mentoring climate components than men. HSC faculty and those receiving mentoring reported greater availability of mentoring climate components than their respective counterparts. Underrepresented minority (URM) faculty did not rate OMCI or OMCA differently than non-URM faculty. Faculty subgroups in this study attached varying levels of importance to the OMC and rated the availability of climate components differently. Factors impacting the importance of the OMC differed from those affecting the perceived availability of the climate components. Based on their relative importance and lack of availability, organizational leaders should create, modify and implement structures, programs, and policies to improve organizational mentoring expectations, mentor-mentee relationships, and mentoring resources, thereby strengthening their OMC.
