Norm-Referenced Vs. Criterion-Referenced Test

It is usual practice to refer to tests, exams, and assessments as Norm-Referenced and Criterion-Referenced, respectively. When learning about assessment and psychometrics, these are frequently among the first ideas students encounter.

It signifies that we are comparing your score to other people’s scores. A criterion, such as a cut score or body of knowledge, is being used to compare your score to.


What is a Norm-Referenced Test?

A ‘normal-referenced’ test compares a test taker’s abilities and performance to other people taking the same test. This type of test measures the test-ability takers to comprehend a predetermined syllabus.

You can evaluate a person’s abilities in various ways, two of which are Norm-Referenced and Criterion-Referenced testing. However, these assessments are used to evaluate performance based on various factors.

What is a Norm-Referenced Test

Different forms and interpretations of the results are also used to present the data. You can also include a group of test-takers competing against another test-taker group in this scenario.

The competition is done to distinguish between the best and the worst students. There is a wide range of topics that test-takers are expected to know, and the complexity of each topic varies.

Standardized testing is also required for this test. Examples of norm-referenced exams include SATs, ACTs, and other standardized tests. The curriculum for these assessments is set by a different panel each time.


What is the Criterion-Referenced Test?

A criterion-Reference test evaluates the test taker’s knowledge of a certain course of study. At the beginning of class, the instructor sets a curriculum and explains it to the students. The exam is administered after the lesson to gauge the level of understanding achieved by the test taker.

Pre- and post-instruction levels of understanding can be assessed with this assessment. The levels can also be used to assess a teacher’s effectiveness in the classroom. The instructor’s lecture material must appear on the test.

According to their teacher or instructor, students are tested on what they learned in class. Criterion-Reference tests include, for example, those administered in school or college by an instructor in a classroom setting. Teachers use this information to assess whether or not a student should be allowed to graduate.

Bruno, a student in the district, performed well on an evaluation in the fall. He got a score of 55%, which is graded as “Proficient.” He scored the 88th percentile, as compared to his fellow students. In the spring of that year, Bruno retook the same test.

Even though his grade level is still “proficient,” his percentile rating has slipped from 38 to 60 this time around.


Referenced by Criteria as Opposed to Referenced by Norms

It is important to grasp the distinction between the two types of assessments to understand what happened.

Criterion-Referenced Test Interpretation

These examinations assess a person’s proficiency to a preset benchmark, learning goal, or performance level. When a test is criterion-referenced, each individual’s results are evaluated against the benchmark, without regard to the results of their fellow students. “cut scores” are typically used to classify pupils into predetermined categories on criterion-referenced examinations.

Even a seasoned examiner cannot discern the difference between a criterion or norm-referenced test merely by looking at it, which is the first thing to realize. Some tests provide criterion-referenced findings and norm-referenced results, so that is where the real distinction lies.

Assessments that use criterion-referenced criteria operate in the same way: The performance of one’s peers has no bearing on their score or how that score is categorized.

Whether a student is a top, mediocre, or low performer, it can be gauged by how well they performed compared to their peers. By looking at their score on a criterion-referenced test, it is impossible to compare an individual student’s performance to their peers.


Evaluating the Results of Tests with Normative Reference

Measures that are norm-referenced compare an individual’s abilities and knowledge with those of the group. Based on individual performances, the norm group’s makeup will change. Students possessing similar grades are randomly selected from a pool of thousands and are frequently used as the norm group for national student assessments.

Other factors such as age, socioeconomic status, race/ethnicity, and many others can limit the norm groups.

The Terms Norm-Referenced and Criterion-Referenced Are Used Interchangeably

Score interpretations are referred to as Norm-Referenced or Criterion-Referenced. Most tests are normally developed and validated for only one.


Is Item Response Theory (IRT) a factor in this?

Response Theory (IRT) evaluates the examinee on a standard normal curve if you have looked at it before (though this is shifted if Rasch). However, criterion-referenced tests can still be assessed using IRT. As long as the cutoff remains consistent and stable across time, IRT can be used to measure a specific corpus of knowledge.

Even computer-adaptive testing can be used in this manner. The NCLEX exam for nurses in the United States serves as an example. It is an adaptive test; however, the outscore is -0.18 (NCLEX-PN on the Rasch scale), and it is certainly criterion-referenced.


Building a Test and Ensuring its Validity

Creating a high-quality assessment is a time-consuming and complex task. Developing and validating takes longer and requires more resources when stakes, volume, and stakeholder incentives are high. You can rely on ASC’s experts to assist you in navigating these murky waters.


What if You Want to Create Exams That Are Smarter and Stronger?

Assessment selection

Assessment selection has become a significant concern in light of the newfound focus on educational responsibility. Many forms of evaluations can gauge a student’s progress. Criterion and Norm-Referenced Tests gauge performance based on distinct criteria, but they are used to evaluate students’ abilities.

There are various ways in which scores can be presented, and you can interpret them in a variety of ways.

Differences Between the Two

The scores of a group of test-takers are compared against those of another group using norm-based tests. These assessment findings can assess the performance of two groups of students that belong to the same grade but in different school systems.

Criterion-based assessments are designed to evaluate students’ performance about certain criteria. It is possible to tell whether or not a student has met the program’s goals by looking at their CRT test scores.


Pros and Cons

The testing goal and objective determine the benefits and drawbacks of norm-referenced versus criterion-referenced assessments. Multiple sources of information, such as textbooks, notes, and syllabi, can be used to test students’ knowledge and skills. Using these assessments, teachers can gauge how well their lessons are progressing. NRT’s content is broader and shallower than CRT’s content.


Variations in the Way Tests Are Administered

Criterion-referenced tests can be administered in various ways, whereas norm-referenced tests must be administered in a standard manner. A close match must be between the testing settings and the norm-setting test takers’ conditions when using norm-referenced tests to determine test-taker performance.

Because of this, the test is programmed. Criterion-referenced testing administration is the opposite.

Interpretation and Reporting of Results

Criterion-referenced and norm-referenced tests report their scores differently. Test results with a criterion reference are summarized in groups or ranges. For instance, the performance could be classified as not proficient, but it could also be competent or highly competent.

This performance’s meaning is evident and tied to achieving the specified curriculum goals.

A percentile rank is used to show the outcomes of a norm-referenced test. This means that a test taker who scores in the 95th percentile outperforms 95 percent of other test-takers. A score in the 50th percentile means that the test taker has done better than half of the other people who took the test.


Why are Tests Important?

Assessment is an essential aspect of the teaching and learning process. Students can demonstrate their knowledge of a subject through assessments. Checking for mastery of standards for a specific subject is also critical—the outcomes of assessments aid teachers in planning lessons and making judgments regarding the general subject matter.

In addition, evaluations assist in highlighting the performance of students. When it comes to highlighting extraordinary performance, test results are essential. For some pupils, the capacity of test scores to distinguish one test taker from the rest might be quite helpful. When it comes to assessing students, there is not a one-size-fits-all approach.

As pupils are diverse, so are their assessments. It is vital to keep in mind that there are advantages and disadvantages to different examinations. Consequently, it is crucial not to obsess about any single test.

In addition to test scores, colleges and universities often look at various evaluation forms.

Why are Tests Important

Focus on the tests that you do well on. Include other noteworthy tests such as essays, portfolios, or interviews if you struggled on a particular test. This will help round out your overall picture of your abilities. You will get a complete image of yourself as a student from various assessments.


Why Teachers Use Standardized and Achievement Tests

To help students succeed, teachers use both classroom and standardized assessments. Teachers may use tests in the classroom for several purposes. An effective instructor-created test will tell the teacher whether or not students have learned the material they were taught in class.

Summative classroom assessments include all of the material studied in class and are given after a unit of study. A final exam is what you should treat this like. Teachers can also use smaller formative exams to cover a more limited amount of material.

The teacher uses a formative assessment to see if the students are ready to move on to the following lesson. Using formative assessments can help teachers plan the next steps in their lessons.
