Technology The technology available is another factor in determining the appropriate assessment tool. Agencies that receive a large volume of applicants for position announcements may benefit from using technology to narrow down the applicant pool, such as online screening of resumes or online biographical data biodata tests. Technology can also overcome distance challenges and enable agencies to reach and interview a larger population of applicants.
How to Measure Stability or Test-Retest Give the same assessment twice, separated by days, weeks, or months. Reliability is stated as the correlation between scores at Time 1 and Time 2. Alternate Form Create two forms of the same test vary the items slightly.
Reliability is stated as correlation between scores of Test 1 and Test 2.

The values for reliability coefficients range from 0 to 1. A coefficient of 0 means no reliability and 1. Since all tests have some error, reliability coefficients never reach 1. Generally, if the reliability of a standardized test is above.
Validity refers to the accuracy of an assessment -- whether or not it measures what it is supposed to measure. Even if a test is reliable, it may not provide a valid measure. The reliability consistency of this scale is very good, but it is not accurate valid because you actually weigh pounds perhaps you re-set the scale in a weak moment!
Since teachers, parents, and school districts make decisions about students based on assessments such as grades, promotions, and graduationthe validity inferred from the assessments is essential -- even more crucial than the reliability. Also, if a test is valid, it is almost always reliable.
There are three ways in which validity can be measured. In order to have confidence that a test is valid and therefore the inferences we make based on the test scores are validall three kinds of validity evidence should be considered.Curriculum Based Assessment/Measurement Developed by: David C.
Rogers, Ph.D., St. Cloud State University CBM is a method for measuring student achievement based on what is taught in the classroom and comparing individual achievement to .
Validity is not a property of the tool itself, but rather of the interpretation or specific purpose of the assessment tool with particular settings and learners. Assessment instruments must be both reliable and valid for study results to be credible.
