  The Force Concept Inventory (FCI) was developed by Hestenes, Wells and
Swackhamer, in order to assess student understanding of the concept of force.
FCI has been used for over 20 years and in different countries. When applying
the inventory in a new context it is important to evaluate the reliability and
discrimination power of this assessment tool. In this study the reliability and
discrimination power are evaluated in the context of Engineering education at a
Norwegian university, using statistical tests, focusing on both item analysis
and on the entire test. The results indicate that FCI is a reliable and
discriminating tool in most cases. As there are exceptions, statistical tests
should always be done when FCI is administered in a new context.
