The purpose of this explanatory, sequential mixed methods study was to understand and explore students' perceptions of advising services before, during, and after an institution has transitioned to a One Stop Student Services Center. The research compared pre-existing data obtained from the Ruffalo Ruffalo Noel Levitz Student Satisfaction Inventory results between the years of 2014, 2016, and 2018 to student interviews conducted in spring of 2021. The reason that this method was chosen is because the researcher wanted to understand more why students rated their academic advising experience as they had when they responded to the RNL-SSI. Overall, students expressed increased levels of satisfaction, at statistically significant levels, with academic advising after the institution transitioned to the one stop student services center. Within the context of the study, implications for policy, practice, and future research are discussed. [The dissertation citations contained here are published with the permission of ProQuest LLC.
