This report package includes five elements: Breadth of Learning Opportunities toolkit - Three tools which examine the breadth of learning opportunities at Policy, School, and Teacher levels. They are aligned to capture and triangulate the policy, school, and teacher perspectives, and the tools are designed to be adaptable to country context and needs. Breadth of Learning Opportunities: A fresh approach to evaluating education systems - A short overview of the BOLO initiative, including the rationale for the BOLO process, descriptions of the tools and questions the tools may be used to answer, and recommendations for adapting the tools. Breadth of Learning Opportunities: Technical Report – A longer report which describes the BOLO tool development process undertaken in 2016-17. This report describes the technical aspects of the initiative at a sufficient level of detail to allow for review, and potentially, replication of the implemented procedures and technical solutions to challenges which arose during the process.
