For example, application forms, tests and interviews can evaluate the applicants’ skills, abilities, relative to the job and so on. To judge the effectiveness of any stage of selection process, two statistical concepts have been of particular importance, Reliability and Validity.
Critical Incidents Technique of job analysis is the recording of behaviours by the worker that are specific to successful or unsuccessful job performance. The qualities needed to do the job also the systematic study of the responsibilties,duties and tasks to perform a job is known as job analysis.
The validity of written job knowledge tests as predictors of job performance and training success was examined. Based on a sample of 363,528 persons and 502 coefficients, meta-analyses were.
Increasing the reliability of your selection process. ability to plan and an understanding of the technical aspects of the job. Don’t use a test that is irrelevant. For example, if someone will rarely be required to make presentations in the job, then it doesn’t make much sense to ask them to do one as part of the selection process.
Parallel forms reliability is a measure of reliability obtained by administering different versions of an assessment tool (both versions must contain items that probe the same construct, skill, knowledge base, etc.) to the same group of individuals. The scores from the two versions can then be correlated in order to evaluate the consistency of results across alternate versions.
A test that is technically adequate meets the criteria for validity, reliability, and norms.. (American Psychological Association 9) Validity is the degree to which a test measures what it is intended to measure. Reliability is the extent to which the test results are dependable and consistent.. Word Count: 1382; Approx Pages: 6.
Content validity identifies specific behaviors, knowledge and tasks required for a given job. For a test to be valid, the content must be directly linked to the job for which a person is applying. Criterion validity determines whether a test accurately predicts on-the-job performance.
Is This a Trick Question? is an information sourcebook for writing effective test questions. The central focus of the sourcebook’s content is derived from standards developed by the National Center for Research on Evaluation, Stan-dards, and Student Testing (CRESST). CRESST’s criteria for establishing the technical quality of a test.
