Cornell has a webpage devoted to assessment. It includes the university's student outcomes (they call them learning outcomes), the process of assessment, campus resources, and their own glossary of terms.
Augsburg has clearly defined student outcomes that come directly out of their mission.
This state school focuses on accreditation as the reason behind assessment, including a new program review process (ironically under review).
Bucknell recently earned the "Excellence in Assessment" designation from the AAC&U. They have clearly defined learning goals, student outcomes, and support systems for assessment. At Bucknell University, the outcomes assessment serves two primary functions. The first is to provide evidence that our students are learning and developing in and out of the classroom, consistent with Bucknell's mission and educational goals, and that our institutional policies, resources and services are appropriately supporting Bucknell's strategic plan. The second function, equally critical, is to provide a mechanism for a continued improvement of all facets of Bucknell education.
Occidental College has a microgrant program to assist faculty and staff. The college identifies some key assessment factors to focus on each year.
Asbury has five goals that they call key conceptional areas. Each of these goals has an identified student outcome "crucial to the liberal ars vision and overall academic mission of the University." Their reasons for assessment are integrity and accountability.
