A free open online course offered through edX now provides an option for students to have a proctored final exam to validate their learning. The nonprofit venture will allow students to take online exams supervised by the Pearson VUE service, with passing students receiving certificates of proctored exam completion. EdX president Anant Agarwal says the proctoring option would significantly add to the value of the certificates. "[Employers and institutions] certainly feel much more comfortable with proctored certificates, because these really reflect the students' own work," he notes. This development comes as the debate over academic integrity in the offering of massive open online courses heats up. Harvard, the University of California, Berkeley, and the Massachusetts Institute of Technology will offer seven courses through edX in the fall. The proctored testing option will be provided for one course.
