ANCAP uses 4 internationally recognized crash tests; offset frontal, side impact, pedestrian and pole impact test.

Crash tests are undertaken by independent specialist crash test laboratories.In all tests crash test dummies are used to facilitate the scientific measurement of the various forces in the crash test. The data gathered is then assessed, using internationally recognized protocols, and scores are determined for various parts of the crash test. Additionally, ANCAP awards bonus points for other safety features such as seat belt reminders.

The overall score is then translated into a star rating, between 1 to 5 stars. The higher scores are awarded more stars.
