Mr Barker Believes That His Students' Capabilities Can Be Made

Mr. Barker believes that his students' capabilities can be made evident through more than a test grade. He requires each student to collect evidence of all the work they have done, including art work, projects they have made in shop class, and extracurricular activities, as well as class assignments. This work is put together in book form and then displayed for the school and parents. Students receive grades based upon this project. This is known as:

A) objective assessment
B) project method
C) portfolio assessment
D) assessment on demand
