Answer:

The answer to the question: What are the measurement requirements of physchological tests, would be, indeed, reliability and validation.

Explanation:

These two characteristics are vital not just to physchological tests, but to all scientific testing tools, and testing techniques that are used, and also in academics. Reliability is the measure that ensures that a test, or tool being used, will provide correct and precise information from a measurement. Validity means that the tool, or test, proves that it is capable of achieving the goals for which it was created and to the highest possible quality and precision level. This means, that the tool, or test, accomplishes the measurements sought by using it, and the results obtained do measure what the test was designed to measure.
