IPC: G09B7/00
Filed: 2016-10-26
Abstract: An assessment system for detecting an instance of cheating, the system including an assessment server 11 configured to generate an assessment including a question and an assessment device 12 for providing the assessment to a user. In addition to receiving input from the user and transmitting the answers to the server, the assessment device is configured to send a first time indicator to the server at a first time and at a second time, subsequent to the first time, send a second time indicator to the server. The assessment server is configured to then determine time differences between respective first and second times. If it has been discovered that the time differences are different from each other by more than a predetermined period, this would suggest the time recorded by the assessment device has been adjusted or otherwise tampered with. An alert suggesting an instance of cheating is then generated and sent to the server or an administrator device. The system also monitors the time taken by the user to answer each of the questions in order to determine a confidence factor.
