Teachers are critical to the success of education grantmaking strategies, yet in talking with them we discovered that the world of philanthropy is often a mystery. GFE's Toolkit for Teacher Engagement aims to assist funders in authentically and effectively involving teachers in the education reform and innovation process. Built directly from the experience of funders, teachers, education specialists, and intermediaries, these principles and strategies were specifically designed to enable funders to share something of their world with teachers while also leveraging teacher expertise and experiences. Whether you are just starting to think about engaging teachers or teacher engagement has been a long-time strategy, you'll find practical tools and real examples of funder-teacher collaboration that will get you started or strengthen your ongoing efforts. The toolkit begins by presenting a framework for funder-teacher collaboration, highlighting a range of involvement strategies from those in which teachers simply provide input to those in which teachers are instrumental in shaping the work itself. This engagement framework is supported by a set of guiding principles for engagement along with real world examples and advice from grantmakers. The toolkit next offers a set of practical tools and lessons learned in the areas of decision-making, process support and communications. The toolkit also features a set of evaluation protocols to help assess the success of engagement efforts.
