Is NNAT an IQ test?

While the NNAT measures cognitive abilities similar to traditional IQ tests, it is not technically classified as an IQ test. Rather, it focuses specifically on nonverbal reasoning skills as an indicator of general cognitive ability. The NNAT is not an achievement test. Achievement tests measure learned knowledge and skills, while the NNAT assesses innate reasoning abilities using novel problems that do not require prior academic knowledge.
