Depth of Knowledge (DOK) is a tool that allows educators to communicate effectively, consistently, and efficiently about the content complexity of learning expectations, instructional materials, and assessment items. We are the only organization that works directly with Dr. Norman Webb, who developed the DOK language system. We use the Webb DOK framework to support educators, districts, assessment developers, states and others to evaluate and improve assessments using DOK and ultimately inform alignment of all parts of the education system.
Contrasting with traditional methods of evaluating the content of student assessments, the DOK framework is designed to measure content complexity, not difficulty. This process is the most effective way to evaluate content to align with learning expectations and assessments as standards continue to evolve and set new expectancies.
