Difference Between NRT and CRT
Tests based on norms measure the performance of a group of trial takers against the performance of another group of test takers. This type of judgment solution can used to compare the performance of seventh graders in a finical school system to the performance of a broad, and possibly more divers ( nationally or state-wide ), group of seventh graders. Criterion based tests measure the performance of test takers relative to particular criteria covered in the course of study. In early words, CRT screen scores can be used to determine if the examination taker has met program objectives.
Pros and Cons
The advantages and disadvantages of average referenced tests vs standard referenced tests depends on the aim and objective of testing. Norm referenced tests may measure the acquisition of skills and cognition from multiple sources such as notes, text and course of study. Criterion referenced tests measure performance on particular concepts and are much used in a pre-test / post-test format. These tests can besides be used to determine if course of study goals have been met. The content of NRT is much broader and superficial than the content measured by CRT.
Differing Methods of Test Administration
Norm referenced tests must be administrated in a standardized format, while criterion referenced tests do not necessitate a standard administration. Since average referenced tests measure the operation of screen takers to early trial takers, it is substantive that testing conditions close match those of the average setting test takers. consequently, the screen administration is scripted. This is in abrupt contrast to criterion referenced testing administration.
Score Reporting and Interpretation
Scores are reported differently for criterion referenced and average referenced tests. standard referenced test results are reported in categories or image. For example, performance may be reported as not adept, technical or very adept. The interpretation of this performance is obvious and directly related to the acquisition of stated course of study objectives. The report of results for a norm referenced examination is accomplished by a percentile rate. A trial taker who scores in the 95th percentile has performed better than 95 % of the individuals taking the screen. In general, scoring at the fiftieth percentile is average and indicates that the test taker has scored better than 50 % of the individuals testing.
