We can calculate a range of collusion indices – which flag unusual patterns of similarity amongst examinees
Honesty. Integrity. Validity.
Test fraud is everywhere. In schools, students cheat off one another, or tell their friend in the next section what is on the test. In Credentialing, candidates will take the test just to steal content and put it on brain dump sites, while others will purchase from such sites without a second thought that they are trading in stolen property.
Our test security services can help you put practices in place to minimizes its effects. While we can use our industry-leading software, SIFT (Software for Investigating Fraud in Testing), to examine the data for irregularities, the cliche hold true here: an ounce of prevention is worth a pound of cure. So we can work with you to identify areas of concern and policies or procedures that might help you. Most notably, we recommend utilizing a test delivery system that can configure appropriate levels of security – like FastTest.
What is a collusion index?
Collusion refers to candidates having similar responses, which can be for a number of reasons: cheating off one another, a teacher helping all the students, or multiple students using the same test form bought from a “brain dump” site. A collusion index is a complex statistic designed to determine the probability of cheating. It is not – like some competitors say – simply looking at the results from two students to see if they are similar!
