Measuring "Hidden" Traits

What Are Psychometric Tests?

Psychometric tests include personality profiles, reasoning tests, motivation questionnaires, and ability assessments. These tests try to provide objective data for otherwise subjective measurements.

For example, if you want to determine someone's attitude, you can ask the person directly, observe the person in action, or even gather observations about the person from other people. However, all of these methods can be affected by personal bias and perspective. By using a psychometric test, you make a more objective and impartial judgment.

Since objectivity is key to using these assessments, a good psychometric test provides fair and accurate results each time it's given. To ensure this, the test must meet these three key criteria:
Standardization – The test must be based on results from a sample population that's truly representative of the people who'll be taking the test. You can't realistically test every working person in a country. But you can test a representative sample of that group, and then apply the results to the specific people whom you test.

Also, a standardized test is administered the same way every time to help reduce any test bias. By using a standardized test, you can compare the results with anyone whose characteristics are similar to those of the sample group.

Reliability – The test must produce consistent results, and not be significantly influenced by outside factors. For instance, if you're feeling stressed when you take the test, the test results shouldn't be overly different from times when you were excited or relaxed.
Validity – This is perhaps the most important quality of a test. A valid test has to measure what it's intended to measure. If a test is supposed to measure a person's interests, then it must clearly demonstrate that it does actually measure interests, and not something else that's just related to interests.
