What is the difference between “online” and “onscreen”?
LAN server-based testing commonly referred to as ‘onscreen’ testing is typically used for high-stakes exams in which successful performance leads to a licence to practice. Onscreen testing relies on the internet to transfer tests, but tests are transferred in an encrypted state and then stored on a local server at the test centre. Tests must then be ‘unlocked’ by the test centre Administrator before they are delivered to a workstation. As well as maximum security, LAN server-based testing eliminates problems associated with internet connectivity during testing and helps robust consistent delivery conditions. ‘Online’ testing, on the other hand relies on the internet to deliver tests. Typically, this is used for low stakes or practice tests, the advantage being that tests do not have to be delivered at specific locations. However, there is a risk of losing connection during an exam, especially in areas where broadband is not prevalent, and there is a greater potential for security breac
