Some Cambridge qualifications have components where the teacher marks their own students’ work. We then check this marking before the release of results to schools. Examples of these types of components can be found in coursework and non-coursework tests in Cambridge IGCSE and A Level syllabuses.
For each of these components, if more than one teacher at the school has marked students’ work, the school must follow a detailed process called internal moderation before they submit their students’ marks and work. Internal moderation helps schools to be sure that every teacher is marking to the same standard.
Each school selects one teacher per component as an internal moderator. The internal moderator is usually a head of department but it can be a subject teacher. It is their responsibility is to check that all teachers for each qualification are marking consistently to the same standard. An internal moderator makes sure ALL students in each teacher’s class have been judged in the same way, against the same marking criteria for that component.
Internal moderation confirms that all marking within each school is consistent and fair to all students who have been entered for the same component.
