Prepare for the CPI - Certified Paranormal Investigator exam with our free practice test modules. Each quiz covers key topics to help you pass on your first try.
These are practice questions written for this site, not questions from the real exam. Each explanation shows why the right answer is right and why the others are wrong.
Question: How should still images be evaluated during evidence analysis?
Answer: B. By comparing to baseline images
Explanation:
The correct answer is comparing to baseline images. A baseline shows what the location looks like under normal conditions, so any difference can be judged against something real. Without that comparison, an odd shape or light spot is only an impression.
Zooming in repeatedly is wrong because enlarging a small area exaggerates noise, compression and pixel patterns, which makes ordinary artifacts look meaningful. Using filters is wrong as the main method because filters change the image and can create the very anomalies you are trying to assess. Skipping blurry images is wrong because it removes evidence before you have evaluated it, and blur itself can point to a camera artifact such as motion or focus trouble.
The rule to remember: judge an image against a known reference and rule out camera artifacts before calling anything unexplained.
Question: Which common household appliance is most likely to cause false positive EMF readings during a paranormal investigation?
Answer: A. Refrigerator compressor
Explanation:
The correct answer is the refrigerator compressor. It is an electric motor that switches on and off, and it gives off a real electromagnetic field. An EMF meter will register that field, so a reading near the appliance says nothing about a paranormal cause.
A wooden bookshelf is wrong because it has no electrical parts and does not generate a field. A glass window is wrong for the same reason: it is a passive material. Ceramic floor tile is wrong because it is also passive, although wiring under a floor can be a separate source worth checking.
The rule to remember: before you record an EMF reading as unusual, locate every powered device, wire and motor nearby and note which readings they explain.
Question: Which type of historical document is most likely to contain firsthand accounts of unusual events reported by early American settlers?
Answer: B. Colonial diaries and personal journals
Explanation:
The correct answer is colonial diaries and personal journals. These were written by the people who lived through events, often soon afterward, so they carry firsthand descriptions in the writer's own words, including accounts of strange happenings.
Congressional records are wrong because they document legislation and official debate, not private experiences of settlers. Land survey plats are wrong because they are maps and boundary descriptions with little narrative. Federal census records are wrong because they list names and household details in a fixed format, with no space for personal stories.
The rule to remember: for a witness's own account, look for personal documents such as diaries, letters and journals, and treat official records as sources for dates, names and property rather than stories.
Start by reading the course page and the policy pages on the Thomas Francis University site, so you know what the course asks of you. Then take a practice set cold, before you review anything, to see where you stand.
Sort your misses by topic. If they cluster around equipment, work through the EMF and environmental detection tools set and the thermal imaging questions. If they cluster around evidence, try evidence collection and analysis, EVP classification and full-spectrum photography. For judgment and conduct topics, use ethics, safety and legal considerations and witness psychology and debunking.
After each set, read every explanation, including those for questions you got right, and write the general rule in your own words. Return to the official course material for each rule you cannot explain.
Finish by repeating the sets you found hardest. Aim to explain why each wrong option fails, because the 70% passing grade rewards steady reasoning across topics, not a single strong area.
