What would prevent an examinee from uploading someone else’s photo when they register and then having that same person show up on test day with a fake ID?

Security is most effective when provided in layers. That’s why ACT relies on more than just the identification match when examinees arrive to take the test. We also print examinees’ photos on the score report that is automatically sent to high schools and use other tools to help detect and deter potential impersonation attempts. These procedures make successfully impersonating another student much more difficult.
