This document includes a final report, guidelines for mentoring communities, and a guidebook for community-based planning developed by the Building Communities for Learning (BCL) project conducted to encourage Pennsylvania communities to develop community-based planning groups to improve the delivery of services for adult learners and maximize adult learning outcomes. The project report describes how four communities received BCL community-based planning start-up grants; three BCL pilot sites assumed a new role as mentoring communities and provided new sites with field-driven training, technical assistance, and support; and all BCL groups received training and technical assistance. The report concludes that there is a great need for community-wide collaboration and community-based planning to improve services for adult learners and improve adult learning outcomes. Two appendixes provide profiles of BCL community-based planning pilot sites and evaluation instruments. The mentoring guidelines describe the following: BCL mentor characteristics, roles and benefits; building a mentoring relationship; impact of mentoring; and communication and critical thinking skills for mentors. The community-based planning guidebook addresses the following: establishing collaboration, recruiting planning group members, defining outcomes, setting goals, strategic planning, group process, evaluation, public relations, and sustainability.
