The STEM Undergraduate Summer Research Experience (SURE) Program provides a holistic approach to undergraduate summer student research to increase student success at Texas State University (TXST), a Hispanic-serving institution. Regarding the 2017-2019 cohorts (composed of 62 undergraduate students), 97 percent persisted after the summer program. After the SURE Program, overall and STEM GPAs were higher in the 2017-2019 cohorts as compared to the control group. SURE students presented 56 posters at national conferences and are second authors in 18 peer-reviewed publications. Fifty-two percent have graduated with their bachelor's degree, 39 percent are attending graduate or professional programs, and 55 percent of the graduates who are working are in STEM-related fields.
