LON-CAPA supports CAPA, the most flexible, powerful, and expandable system for formative and summative assessment out there. CAPA covers everything from the most simple multiple choice responses to sophisticated symbolic math, and allows all components to be mixed and matched into complex multipart and multiple-response structures. All components of problems can be randomized, so that different students get different versions of the same problem.

CAPA has a superset of most any homework and exam systems’ functionality, and thus content from several other systems has successfully been ported into CAPA.
