Pearson VUE:

Online learning venture edX continues to transform higher education by announcing today its agreement with Pearson VUE to offer learners the option of taking a proctored final exam.
“Our online learners who want the flexibility to provide potential employers with an independently validated certificate may now choose to take the course exam at a proctored test site,” said Anant Agarwal, president of edX. “This option enhances the value of our courses in the real world, helps us maintain our goal of making high-quality education both accessible and practical and thus is a natural evolution of ed’s core philosophy of transforming lives through education.”
Pearson VUE, a Pearson business, is the global leader in computer-based testing. Due to this new agreement, edX learners now have the option of taking a course final exam at one of over 450 Pearson VUE test centers in more than 110 countries. Proctors at the centers will verify the identity of the examinee and administer the tests. Examinees using the Pearson VUE centers will take the same rigorous exam as online learners and will be charged a modest fee for the proctoring service. EdX will offer the option to test takers for one of its online courses this Fall.
