A scheme of work defines the structure and content of a course. It maps out clearly how resources (e.g. books, equipment, time) and class activities (e.g. teacher-talk, groupwork, practicals, discussions) and assessment strategies (e.g. tests, quizzes, Q&A, homework) will be used to ensure that the learning aims and objectives of the course are met. It will normally include times and dates. The scheme of work is usually an interpretation of a specification or syllabus and can be used as a guide throughout the course to monitor progress against the original plan. Schemes of work can be shared with students so that they have an overview of their course.

A scheme of work is a plan of what will be covered in each week or session of the learning programme or course.  It can be very detailed or brief. A scheme of work may, for example, consider how many lessons will be needed to cover a specific theme.  It can also support communication and planning between departments. Once it has been finalised, a scheme of work can be used to write lesson plans.
