4 Overall, various failure components can disrupt the test procedure. If a fault occurs, time and duration may affect the actions to be taken. Some suitable actions will be described below.

91 Provide the test as a pen & paper exam. The ONYX help authoring tool offers a PDF export of the created test. To continue the e-test, the examiner needs to adapt the configuration of the course element in the learning platform accordingly. Both the exam mode and exam control must be enabled.

98 If you switch to a pen & paper exam, the test must be assessed manually. Test results may also be entered in the assessment view for the e-test. The result data can then be further processed electronically.

105 After the power failure, the PCs must be restarted. All participants must log back into the learning platform and reopen the test. The rest of the procedure is analogous to the workflow in the event of a client PC failure (cf. procedures guide for the failure of a client PC).

131 As soon as faults occur in the network, all participants should be asked to interrupt processing the test. Only then it can be guaranteed that the exam situation will be the same for all participants. During the network failure, the currently displayed page can be further processed. However, it will not be possible to open new test pages (e. g. navigation via the navigation tree, next or previous buttons) or to finish the test.
132
133 (% style="letter-spacing:0.0px" %)In contrast to a power failure, the participant will remain logged in to the system (learning platform / ONYX) and does not have to reopen the test. As soon as the network is available again, the participant can continue to work on the active test.
134
135 (% style="letter-spacing:0.0px" %)If the exam is limited in processing time, the participant must be credited for the processing time lost due to the network failure. To do this, select all participants using the exam control and choose the option “Continue”. Set the additional processing time in the “Continue test” dialogue and confirm your settings with “Yes”. The test does not have to be restarted.
