The American Association of Community Colleges' (AACC) Plus 50 Initiative (2008-2011), funded by The Atlantic Philanthropies, was created to build the capacity of community colleges nationwide to develop programming that engages the plus 50 learner. The Initiative supported a pilot group of 13 two-year institutions to develop or expand college offerings in three areas: workforce training and career development; learning and enrichment; and volunteering. It was later expanded to include affiliate colleges that were paired in learning partnerships with experienced Plus 50 colleges. This document contains the collective wisdom of the Plus 50 grantee colleges on the essential elements of a successful Plus 50 program: what community colleges should strive for in developing and implementing their own programming. These Standards of Excellence are not prescriptive--there is ample room for innovation. Instead, they are guidelines for the basic building blocks that should be in place for a program to have the desired impact on its clients: providing plus 50 learners with the knowledge, skills, and resources that support purposeful lives through education, work, and service. For each standard, this document provides (1) a definition, (2) an explanation for how this Standard of Excellence creates impact among plus 50 learners, and (3) a list of the "foundational elements:" actions or components required to most effectively develop this Standard of Excellence. Each Standard also features one promising practice derived from program innovations at the grantee colleges. (Contains 2 footnotes.) [This paper was prepared by the LFA Group.]
