"The guideline provides a roadmap, flagging at which points in the process of commissioning, implementing and managing evaluations CEH-related considerations could and should be taken into account. As such, it covers the steps involved in preparing for an evaluation; developing the terms of referenc ... e (ToR) for an evaluation; managing the evaluation; and the post-evaluation development of an improvement plan and communication of the evaluation findings and recommendations. Given the often technical and complex nature of CEH-related issues, the guideline also provides an overview of the key concepts and features of CEH that underlie the rationale and dimensions of the evaluation criterion."
