Our tests are data-driven and undergo rigorous quality-control procedures to ensure validity and reliability. TestGorilla’s proprietary algorithms continually enhance test quality and ensure they provide accurate results.
TestGorilla regularly solicits feedback from both applicants and recruiters. This feedback helps us identify areas for development and make necessary changes to improve our testing process.
Each TestGorilla test comprises a minimum of 100 questions, but candidates will only see 12-20 questions during each test. This prevents overexposure and ensures the fairness and accuracy of the assessment.
Furthermore, we retire questions from the question bank after extended usage to maintain fresh and accurate assessments.

TestGorilla vs. Ducknowl: Anti-cheating measures
Falsifying prescreening job applications is all too prevalent, with candidates often looking up answers online or getting assistance from others. So, for pre-employment tests to have any validity, you must have strong anti-cheating measures in place.
TestGorilla’s anti-cheating measures
TestGorilla implements various measures to ensure that candidates don’t cheat while taking assessments.
Copy and paste is disabled by default, preventing candidates from leaking questions. Plus, test-takers see a different set of questions each time they attempt an assessment.
TestGorilla also takes steps to prevent candidates from researching during assessments. Our platform lets you enforce time limits so candidates can’t look up answers.
The system notifies you if a candidate opens another window during a test, and you can choose to record a candidate’s screen or take snapshots using their webcam with the candidate’s permission.
Ducknowl’s anti-cheating measures
Ducknowl detects when candidates move their mouse away from the test window and issues them a warning. This stops applicants from researching the answers to test questions online.
The platform can also be set to take screenshots of test-takers so recruiters can check if they have anyone in the room helping them. However, no further anti-cheating measures are listed on the Ducknowl website.
