The field of criterion-referenced testing has developed quickly since the first papers on the topic by Glaser and Popham and Husek Glaser, and later, Popham and Husek, were interested in assessment methods that could provide information on which to base a number of individual and programmatic decisions arising in connection with specific instructional objectives or competencies. Norm-referenced tests were judged to be inappropriate because they provide information that facilitates comparisons among examinees on broad traits or constructs. These tests were not intended to measure specific objectives. And even if items in a norm-referenced test could be matched to objectives, typically there would be too few test items per objective to permit valid criterion-referenced test score interpretations.

Many educators and members of the public fail to grasp the distinctions between criterion-referenced and norm-referenced testing. It is common to hear the two types of testing referred to as if they serve the same purposes, or shared the same characteristics.

Difference Between Criterion-Referenced & Norm-Referenced Tests

A criterion-referenced test is a style of test which uses test scores to generate a statement about the behavior that can be expected of a person with that score. Most tests and quizzes that are written by school teachers can be considered criterion-referenced tests. In this case, the objective is simply to see whether the student has learned the material. Criterion-referenced assessment can be contrasted with norm-referenced assessment and ipsative assessment. Criterion-referenced testing was a major focus of psychometric research in the s. A common misunderstanding regarding the term is the meaning of criterion. Many, if not most, criterion-referenced tests involve a cutscore , where the examinee passes if their score exceeds the cutscore and fails if it does not often called a mastery test.

Without a frame of reference, a raw score by itself does not tell us how much a student knows or what he or she can or cannot do within a content area. A test score must be referenced or compared to something to give meaning to it. For example, a student receives a score of 88 on a test with no other information provided. There are four frames of references for interpreting test scores are explained: Ability, growth, norm, and criterion referenced interpretations. The table below summarizes the four types of frames of reference for interpreting test scores. For this course, we will concentrate on two of them: norm-referenced NRT and criterion-referenced CRT interpretations, as these are the ones commonly used in school reports. Frames of Reference for Interpreting Test Scores.

Norm-referenced tests (NRT) help compare the performance of one student with the performances of a large group of students, while criterion-referenced tests.

Norm-referenced refers to standardized tests that are designed to compare and rank test takers in relation to one another. Norm-referenced tests report whether test takers performed better or worse than a hypothetical average student, which is determined by comparing scores against the performance results of a statistically selected group of test takers, typically of the same age or grade level, who have already taken the exam. Test developers use a variety of statistical methods to select norming groups, interpret raw scores, and determine performance levels.

Criterion and norm referenced tests in the education system: livening up the debate

Due to the recent and unprecedented emphasis on educational accountability, assessment selection has become an important consideration. There are various types of assessments that can be used to measure student performance. Additionally, scores are reported in different formats, interpreted differently and target different content.

Patricia C. Montgomery, Barbara H. The purposes of this article are 1 to compare the similarities and differences between norm-referenced and criterion-referenced tests and 2 to summarize how each should be used in the assessment of developmental performance in children.

Even an assessment expert couldn't tell the difference between a criterion-​referenced test and a norm-referenced test just by looking at them.
