Mass enrollment of minorities has been a trend in higher education over the last 30 years. Despite the increase of minorities enrolling in higher education, there is a gap in graduation rates and expected time to graduation when compared to Whites. The disparity in success rates of minority groups is of special importance as it highlights how providing access to postsecondary education is not meeting the needs of all students. This study compares the perceptions of supportive environments in Hispanic Serving Institutions (HSIs) among students who are African American, Hispanic, and White. This study is framed through J. Stacy Adams' equity theory, which posits if distribution of resources is fair, then equity is present. Equitable support among African American, Hispanic, and White students attending HSI colleges and universities is the topic of this study. The study investigated the extent of difference for nine indicators of supportive environments among these racial or ethnic groups using the 2016 and 2017 version of the National Survey of Student Engagement (NSSE) provided by the Indiana University Center for Postsecondary Research (IUCPR). Indicators from the NSSE include academic support, learning support, diverse interaction, social opportunities, campus activities, campus events, health and wellness, and non-academic support, and a composite variable called overall support was created. Two-fifths of the participants in the study were randomly sampled from the total number of participants in the original data provided by IUCPR. A one-way ANOVA revealed a significant difference among all groups however the effect size was small. The Kruskal-Wallis H was used to statistically determine the extent of differences among the three groups for eight individual dependent variables. The results indicated significant differences and small effect sizes among groups for eight individual dependent variables. Post hoc tests revealed differences between African Americans and Whites, and Hispanics and Whites for almost all types of support.
