With many efforts underway across the United States, state education agency (SEA) leaders have the opportunity to utilize the expertise of their contacts in other SEAs and regional comprehensive centers (RCCs) in their region and throughout the country to exchange ideas and share the lessons they have learned about involving stakeholders in meaningful and productive ways. To assist with this exchange, the authors provide a detailed example of one state's experience with stakeholder engagement and communication efforts: Colorado. The authors offer this Colorado case study to help clarify the key decisions, events, print and Web resources, and other specific communication approaches that SEAs and districts need to consider. In addition, this case study can be used as a companion piece to "A Practical Guide to Designing Comprehensive Teacher Evaluation Systems" (www.tqsource.org/publications/practicalGuideEvalSystems.pdf; Goe, Holdheide, & Miller, 2011), a tool that guides state planners through the eight components of teacher evaluation design. Component 2 of this tool, "Securing and Sustaining Stakeholder Investment and Cultivating a Strategic Communication Plan," lays out the key considerations in four focus areas for ensuring stakeholder support for a new system. The four steps are (1) identifying the stakeholder groups, (2) establishing group roles and expectations, (3) developing a communication plan, and (4) soliciting feedback. This case study is organized around Colorado's activities and lessons learned under each of these four areas. The brief concludes with an overview of additional guidance and lessons learned from stakeholder engagement efforts in Teacher Incentive Fund districts and through work by the Bill & Melinda Gates Foundation, as well as an overview of existing resources on this topic area.
