The Keyway project aimed to support the evaluation and evidence-based reform and design of guidance policies and services by developing the Keyway set of tools for guidance organizations to measure the impact and results of their guidance services. The Keyway project connected guidance organisations and services to Key Performance and Impact Indicators. The Keyway partnership made up of diverse organisations within the field of school education and guidance (a university, a Provincial Council, research and training organisations and organisations directly providing guidance services), built upon the existing research to develop a methodology and tools to promote the practical collection and analysis of evidence indicators related to the impact and results of academic and career guidance activities. To do so, the Keyway project involved more than 250 education and career guidance professionals, both internal and external to the Keyway partnership. The Keyway partnership actively involved academic and career guidance practitioners within the project through quantitative and qualitative consensus methodologies to develop its products. In this way, the Keyway project not only succeeded in bringing together the experience in the field from the 4 countries represented by the partnership, but also additional academic and career guidance professionals and experts. The Keyway project provides tools to guidance practitioners so that they know how and why they should invest within the analysis of the impact and results of their guidance services and are better prepared to provide evidence to policy and budgetary decision-makers. The Keyway project identified and analysed the diverse areas of impact that guidance activities have on the lives of citizens with the result of the Keyway Conceptual Impact Map. The project partnership then went on to define Key Indicators of Performance and Impact (KPIs) based on desk research and consensus methodologies. These indicators (defined and supported with bibliographic references) give guidance services the needed measures to evaluate and valorise the services they provide. Finally, the project developed a Methodological Guide to support guidance services as they begin to carry out performance, results and impact evaluation with the Keyway tools.The project had the objective of consulting and incorporating the opinion of at least 40 external school education guidance experts through consensus methodologies in small group sessions and an online consultation process - in total the project involved more than 60 experts in this role. The involvement of these experts supported the quality and applicability of the activities and intellectual outputs of the Keyway project. The Keyway tools has succeeded in bringing forward the research in the field and making it available at the operational level through the Keyway tools to promote modern, dynamic and efficient guidance systems within school education.The Keyway project gave guidance services specific tools to begin the evaluation of their performance and impact. The project tested the tools specifically with professionals from 8 organisations, but also presented and contrasted first impressions of the resources with more than 120 professionals through the multiplier event practical seminars. The longer-term benefits of the project can also be seen through the innovation and incorporation of the Keyway tools and methodology within the training programmes of the project partners which directly affect school education and guidance professionals at the local and regional levels.
