Background: The Council of Chief State School Officers' State Collaborative on Assessment and Student Standards Health Education Assessment Project (SCASS-HEAP) allows states to pool financial and human resources to develop effective ready-to-use health education assessment resources through a collaborative process. The purpose of this article is to describe the extensive ongoing development of the SCASS-HEAP and its benefits for important stakeholders in health and education. Methods: A review of the products from the first decade of the SCASS-HEAP was undertaken. Results: The SCASS-HEAP supports a comprehensive systems approach to helping educators focus effectively on the most important skills and issues in child and adolescent health and gives health education a place at the school reform table, providing visibility and credibility and promoting the essential links between health and learning. Conclusion: State education agencies and school districts can use SCASS-HEAP materials for assessment and, perhaps more importantly, to help teachers modify and improve instruction at the classroom level for increased student learning.
