criterias

Criteria are standards, benchmarks, or conditions that items, actions, or decisions must meet to be judged acceptable or successful. They guide evaluation by providing a basis for comparison, helping to determine eligibility, quality, or suitability. Criteria can be qualitative or quantitative and are used across fields such as research, evaluation, procurement, and human resources.

In standard English, the plural of criterion is criteria. The form criterias is rarely used and is generally considered nonstandard in formal writing, although it may appear in casual speech or as a mistaken plural in some contexts.

Criteria can be hard or soft. Hard criteria are objective and measurable, such as numbers, percentages, or timeframes. Soft criteria are subjective and value-laden, such as aesthetics, usability, or cultural fit. Criteria can be mandatory requirements, optional considerations, or weighted factors in a decision model. They may be independent or interdependent, and can be organized hierarchically, with primary criteria guiding core judgments and secondary criteria refining the assessment.

Applications often involve creating a criteria list and, for each option, scoring, ranking, or filtering according to how well it satisfies the criteria. Techniques such as rubrics and multi-criteria decision analysis (MCDA) formalize this process to improve consistency, transparency, and defensibility of outcomes. Properly defined criteria should be observable, verifiable, relevant to the objective, and free from ambiguity to support reliable judgments.
