The greatest damage they have inflicted on public education, however, lies not in a mistrained corps of educators but in the effects of their virtually evidence-free theories and practices on the K curriculum as conveyed by these educators and the textbooks used in K

There are probably some items which could be improved. The test definitely needs to be supplemented by other measures e.
This test should not contribute heavily to the course grade, and it needs revision. This is the general form of the more commonly reported KR and can be applied to tests composed of items with different numbers of points given for different response alternatives.
When coefficient alpha is applied to tests in which each item has only one correct answer and all correct answers are worth the same number of points, the resulting coefficient is identical to KR Further discussion of test reliability can be found in J.
Standard Error of Measurement The standard error of measurement is directly related to the reliability of the test. Whereas the reliability of a test always varies between 0. For example, multiplying all test scores by a constant will multiply the standard error of measurement by that same constant, but will leave the reliability coefficient unchanged.
A general rule of thumb to predict the amount of change which can be expected in individual test scores is to multiply the standard error of measurement by 1. The smaller the standard error of measurement, the more accurate the measurement provided by the test.
Further discussion of the standard error of measurement can be found in J. Such statistics must always be interpreted in the context of the type of test given and the individuals being tested.
Lehmann provide the following set of cautions in using item analysis results Measurement and Evaluation in Education and Psychology. Holt, Rinehart and Winston, Item analysis data are not synonymous with item validity.
An external criterion is required to accurately judge the validity of test items. By using the internal criterion of total test score, item analyses reflect internal consistency of items rather than validity.
The discrimination index is not always a measure of item quality. There is a variety of reasons an item may have low discriminating power:Students’ Performance and Attitudes: A Meta-Analysis Erin Pahlke Whitman College Janet Shibley Hyde and Carlie M.

The report includes findings from interviews with state education officials in all states, surveys of nationally representative samples of districts, principals, and teachers, data from consolidated state performance reports, and analyses of student achievement trends on state assessments and NAEP.
School accountability—the process of evaluating school performance on the basis of student performance measures—is increasingly prevalent around the world. In the United States, accountability has become a centerpiece of both Democratic and Republican federal administrations' education policies.
