This poster submission for the NSF Grantees Poster Session focuses on outside-of-the-classroom services and support for undergraduate engineering students. These supplemental educational experiences contribute significantly to student retention and engagement. The poster will describe several initiatives implemented at a small, Midwestern, STEM-focused campus through a National Science Foundation (NSF) STEM Talent Expansion Program (STEP) grant. The theme of capacity building is all about developing collaborative relationships, leveraging existing services, and growing sustainable informational and programmatic infrastructure on campus. The opportunity to implement many, varied initiatives allows for a multi-pronged approach to improving retention. Assessment of these initiatives can then help to determine the most viable, effective initiatives, which can then be institutionalized to strengthen student success. The initiatives highlighted in the poster will include a retention center learning space; career exploration industry partnerships; undergraduate research and professional travel; peer advising; peer mentoring; and pre-college outreach. The poster will show the best practices for planning and development of programs, explain assessment methods, and highlight key outcomes. ; Comment: 9 pages
