The Kryterion solution includes built-in features that can cause "technology alerts" or warnings to test takers, based on certain test taker actions that may be indications of cheating. Kryterion locks down various keyboard combinations to prevent undesirable keyboard actions like copying and pasting and CNTRL + PrntScrn. If a test taker attempts to use prohibited action, the Kryterion solution sends a technology Alert to the student asking them to cease that type of action.
