written by J. S. Aslanides and Craig M. Savage

This 24-question research-based multiple-choice test is designed to evaluate students' understanding of special relativity concepts taught in introductory courses.

Concepts investigated include the first postulate, second postulate, time dilation, length contraction, relativity of simultaneity, inertial reference frames, velocity addition, causality, and mass-energy equivalence.

The survey should be given in a 30-minute period. Statistical results are currently limited. A summary of the survey construction and results are available in Relativity concept inventory: Development, analysis, and results, PRST-PER 9 (1), 010118.
