Abstract

The program CONNECT is constructed to treat a problem in security analysis, although other applications relevant to educational testing are also possible. In the basic application of the program, data are available from separate analyses applied to different test sections to identify incorrect answer keys for the section employed exactly or nearly exactly by a group of test takers. It is often true that for different test sections, the groups of test takers identified are not identical but do overlap. The problem is to employ all the available data to identify groups of test takers who appear to have interacted on some sections.
