Throughout history mental health has played an important role in the legal system, specifically regarding matters of competency and sanity. Issues concerning competency to stand trial have grown throughout history and cover a large breadth of topics including, but not limited to: predictor variables, malingering, mental retardation, competency standards in execution, and the validity of competency assessments. The issue of competency in legal proceedings is rooted in English Common Law as early as the 17th century (CITE- ALawPsych&pol).

Clinical variables are of foremost importance in a competency evaluation. Individuals scoring lower on IQ measurements of mental functioning are more likely to be considered IST than those functioning at a higher rate. Additionally, being diagnosed with a mental illness, specifically one exhibiting symptoms of psychosis and non-psychotic major disorder, tend to be correlated with an IST decision. Conversely, defendants with a diagnosis of drug, alcohol, or non-psychotic minor disorders are more likely to be found CST.
