These computer-based exams are given by appointment only. Examinees register through Castle Worldwide's Web site.

CASTLE exams are very easy to use and require no prior computer experience to operate. The demonstration module walks examinees through all of the system's features and functionalities and allows as much time as necessary to become completely familiar with the system.

CASTLE exams permit candidates to skip questions, go to previously answered items, mark items for later review, go to specific items, and review answers before submitting the test for scoring. The examination data is delivered via a secure, password-protected website. The examination and the candidate's answers are constantly uploaded to the test provider's secure server.
