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
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?
