Reliability, validity and norming sample populations play critical roles in the usefulness of assessment instruments used in forensics assessments. These three facets of assessment help to determine whether or not the results the assessment yield is credible. Additionally, they each help to evaluate a particular aspect of an instrument, although there is generally a degree of correlation between these factors.

Validity is simply the accuracy of a test to effectively measure the particular phenomenon that a researcher is attempting to measure. There are different types of validity including construct validity, content validity, and criterion-related validity (Richmond, 2013). These different facets of validity determine the accuracy of an assessment in terms of its construct, its usefulness is appropriately sampling the different components of the construct, and its accuracy in foretelling performance. Reliability is the facet of an assessment to provide consistency in its results over time. Reliable tests can generally yield the same results regardless of when an assessment is taken. It is important to realize that "without reliability, there can be no validity" (Richmond, 2013).

Each of these facets of forensic assessment are extremely important when completing testing in this field. For instance, if a researcher was using an instrument to assess proclivity for future violence, it is important to use an instrument which tests this particular construct. A personality test might apply to the researchers needs; however, another instrument such as an IQ test would not. It is worth mentioning that there are forensic instruments more specific to violent tendencies than either of the aforementioned ones.
