Assessment methods in education and psychology are critical for understanding and measuring individual performance and achievement. Two primary types of assessment are criterion-referenced tests and norm-referenced tests, each serving distinct purposes based on what they aim to measure and compare.

Criterion-Referenced Tests (CRTs) are designed to assess whether a particular student has achieved specific skills or knowledge standards. These tests measure an individual's performance against a predetermined set of criteria or learning standards, without comparison to other students’ performances. For instance, a driving test that evaluates whether an applicant can safely operate a vehicle exemplifies a criterion-referenced assessment—success is defined by meeting specific safety criteria, not by outperforming others (Popham, 2009). These tests are often used in educational settings to determine mastery of content, licensing examinations, or skill evaluations where the goal is to verify competence in specific areas (Meyers & Jones, 2012). The emphasis is on individual proficiency rather than comparative ranking, making criterion-referenced assessments essential for certification and instructional improvement.

Norm-Referenced Tests (NRTs), on the other hand, aim to compare an individual's performance to a larger group, often called the norm group. These assessments are designed to rank or categorize individuals relative to their peers. An example is the SAT or IQ tests, which provide percentile rankings indicating how a test-taker performs relative to others in the same age or grade group (Crocker & Algina, 2008). The primary purpose of norm-referenced tests is to identify relative performance and variability across a population, often used in settings such as college admissions, gifted program placements, or employment screening where comparison to others is necessary (Koretz, 2010). Thus, a contrast between the two test types lies in their purpose: criterion-referenced tests focus on individual mastery, while norm-referenced tests evaluate performance in relation to a normative sample.

To illustrate, an example of a criterion-referenced test is a driver's license exam that assesses whether a candidate can demonstrate specific driving skills, and a passing score indicates that the individual has met the standards set by the licensing authority. Conversely, an example of a norm-referenced test is the GRE, which compares a test-taker's performance to other applicants and provides percentile rankings to interpret the results.

Understanding the distinction between these assessments is essential for educators, psychologists, and policymakers to select appropriate evaluation tools aligned with their objectives. Criterion-referenced tests are vital when the goal is to certify or ensure competency, whereas norm-referenced tests are crucial for understanding relative standing within a population (Camilli, 2006).
