Abstract: A tamper-resistant electronic assessment system using time indicators to ensure electronic assessment integrity is provided. The assessment system may include an assessment server configured to generate an assessment instance including at least one question and an assessment device configured to present the assessment to a user. The assessment device may send a first current time indicator to the assessment server, receive the assessment instance, receive user answers, send the user answers to the assessment server, and send a second current time indicator to the assessment server to facilitate verification of the assessment integrity. The assessment server may further determine first and second time differences between the first current time indicator and second current time indicator and the current times when they are received by the assessment server. The assessment server may further generate an alert when the first and second time differences differ by more than a predetermined period.
