Extra credit is an academic concept, particularly used in American schools. Students are offered the opportunity to undertake optional work, additional to their compulsory school work, in order to gain additional credit that would boost their grades.

Reasons for extra credit

Teachers employ extra credit for a variety of reasons. For example, it may be felt that students who are highly capable may benefit from additional challenge that might not be suitable as required work for all students. Extra credit may also be used as a way to allow a student to improve his or her grade after weak performance earlier in a course. In both of these cases, extra credit can promote differentiated instruction

Method of computation

Typically, participation in extra credit can only improve one's grade. Points might be added to an existing activity, for example, if the student correctly answers a more difficult portion of a test than would be required to meet the objectives of a unit. Optional activities may also add points or marks used in an overall grade computation. This may, for example, increase the numerator of the fraction used in computing an overall percentage, while leaving the denominator unchanged. This can lead to grade percentages that exceed 100% unless the policy used for grade computations cap a grade at a maximum value.
