Because the MD5 is a timed power test, it demonstrates strong test-retest reliability. Research indicates that scores remain stable over short intervals, meaning the results are not likely due to luck or temporary mood swings, but rather a reflection of the test-taker's stable cognitive capacity. Validity of the MD5
The MD5 is a "high-range" mental ability test. It typically consists of 57 items that must be completed within a strict 15-minute time limit. Unlike verbal tests, it uses grids, patterns, and sequences, making it less dependent on language skills and more focused on "fluid intelligence"—the ability to solve new problems and identify patterns.

The 15-minute limit mimics high-pressure environments. Because the MD5 is a timed power test,
Because the MD5 is non-verbal, it possesses higher face validity for international or diverse workforces. It minimizes the bias that often plagues verbal reasoning tests, where non-native speakers might struggle regardless of their actual cognitive power.

Reliability refers to the consistency of a test. If a candidate took the test twice under identical conditions, would they receive the same score? Internal Consistency
Validity asks if the test actually measures intelligence and if those results predict real-world success. Construct Validity
