The review of the literature indicated that a notably smaller number of nontraditional students persist to graduation than do traditional students. There is a significant body of scholarship regarding the experiences of nontraditional students; however, only a few studies have specifically examined persistence. Sparse research exists on the nontraditional subgroup of linguistic minority (LM) students who persist to graduation. This quantitative study was motivated by sparse research available in the areas of persistence to graduation for nontraditional students, particularly for nontraditional LM students. The purpose of this quantitative study was to compare the differences in the variables of perceived language proficiency, familial support, and educational success across the nontraditional subgroups of monolingual English (ME) and linguistic minority (LM) students for persistence to graduation. Additionally, the descriptive data for college generation and financial resources were used to look for additional differences in persistence to graduation between the groups of ME and LM students. A total of 104 participants, all of whom were graduates, completed a survey about their undergraduate experience at the institution in the study. Based on the results of the survey, independent samples t-tests were run on the scale variables of perceived language ability, educational success, and familial support. All three t-tests showed significant differences between the subgroups. The H[subscript o] was: There are no defined differences between ME and LM nontraditional students for persistence to graduation. ([mu subscript 1] = [mu subscript 2]) was rejected. The index variable of college generation indicated that fewer students in the LM subgroup were first-generation students than in the ME subgroup. The variable of financial resources was not a factor for persistence in this study. Further research for nontraditional students, specifically for nontraditional subgroups of students, is still needed to fill the gaps in research and increase future persistence to graduation rates.
