Where do I start? A Test Security Plan

A cliche that is often used in the field of test security is “An ounce of prevention is worth a pound of cure.” There’s a reason it is used so often: it is true. ASC can help you develop a Test Security Plan and implement delivery protocols that protect your intellectual property and the integrity of exam scores.

Types of psychometric forensics to help test security

There are different levels of psychometric forensics. What makes the most sense for the issues you are having?

Intra-Examinee

Is there anything unusual about this examinee unrelated to everyone else? Did they answer “C” to every item? Did they spend 10 minutes on each of the first 5 items and skip the rest? Did they get a high score in a suspiciously short time?

Inter-Examinee

Is there anything unusual about this examinee compared to others? Are there nearby examinees that have almost the same response vector?

Group-Level

Group-level analysis provides additional insight. Do certain schools or teachers do unusually well? Do certain test centers have crazy-high pass rates but short test times on average?
