In psychological assessments, norms refer to standardized benchmarks that allow practitioners to compare an individual's performance to that of a larger group. These norms are typically based on data collected from a representative sample of the population, which provides a frame of reference for evaluating test scores, behaviors, or cognitive abilities. By using norms, clinicians can better understand where a particular individual falls within the general distribution of scores, which aids in determining whether their performance is typical, above average, or below average, ultimately guiding clinical decisions and interventions.

The concept of norms is fundamental in assessments as it ensures that the interpretation of an individual's results is meaningful in a broader context, taking into account variations across different populations and demographics. This comparison supports evidence-based practice, as it helps therapists make informed conclusions about a client's functioning compared to the established benchmarks.

Other potential options do not effectively encompass the definition of norms within psychological assessments. For example, evaluating socioeconomic status doesn't directly relate to performance measures or test scores. Current trends in mental health treatments and average outcomes from therapy sessions are also unrelated to the comparative benchmarks that norms provide in assessment contexts.
