Questionmark Secure for iPad enables participants to take and complete online tests and exams delivered via Questionmark OnDemand or Questionmark Perception. Questionmark Secure is designed to provide a secure environment for online tests and exams that reduces the risk of cheating and complements an organization’s other defenses for mitigating threats to content security and results integrity. Academic institutions, businesses and governmental organizations use Questionmark’s technologies to create, deliver and report on online tests and exams. These online assessments may be delivered via a standard browser, such as Safari, Firefox, Internet Explorer, etc. However, certain high-stakes tests and exams warrant the additional protections provided by Questionmark Secure, including: preventing the copying or printing exam material; accidentally exiting a test; gaining access to materials (either locally or Internet-based) that could give an unfair advantage. Questionmark Secure delivers online assessment content while disabling key system functions such as task-switching, screen captures and other functions that might jeopardize the fair and secure completion of the assessment.
