Veterans and students who are currently members of the U.S. Armed Forces have a long and rich history with higher education. Despite this, little quantitative research exists that examines factors that influence academic outcomes and provide results that can be acted upon by institutions, such as community colleges, to improve the academic outcomes for this population. The purpose of this study was to explore which factors, if any, influence current U.S. Armed Forces members? and veterans? cumulative GPA at community colleges with the use of data from the Community College Survey of Student Engagement (CCSSE). Using a blocked form of linear stepwise regression, along with the input-environment-output model, this researcher found 21 variables to be statistically significant predictors of current U.S. Armed Forces members' and veterans' cumulative GPA. For the input variables, high school GPA, race-African American, race-Hispanic, race-White, having a credential, being married, having supportive friends, being a full-time student, being a first-time student, and being female were predictors of GPA. The statistically significant environmental variables included learning effectively on one's own, participated in a student success course, participated in class, tutored other students, come to class unprepared, skipped class, taking an honors course, preparing for class, challenging exams, number of papers written, and analyzing ideas and theories were significant predictors of GPA. This study adds to the limited quantitative large-scale studies involving veterans and U.S. Armed Forces members at community colleges.
