Job knowledge tests, sometimes referred to as achievement or mastery tests, typically consist of questions designed to assess technical or professional expertise in specific knowledge areas. Job knowledge tests evaluate what a person knows at the time of taking the test. Unlike cognitive ability tests, there is no attempt to assess the applicant's learning potential. In other words, a job knowledge test can be used to inform employers what an applicant currently knows, but not whether the individual can be relied on to master new material in a timely manner. Job knowledge tests are not appropriate when applicants will be trained after selection in the critical knowledge areas needed for the job.
Job knowledge tests are used in situations where applicants must already possess a body of learned information prior to being hired. They are particularly useful for jobs requiring specialized or technical knowledge that can only be acquired over an extended period of time. Examples of job knowledge tests include tests of basic accounting principles, computer programming, financial management, and knowledge of contract law. Job knowledge tests are often constructed on the basis of an analysis of the tasks that make up the job. While the most typical format for a job knowledge test is a multiple choice question format, other formats include written essays and fill-in-the-blank questions.
Licensing exams, agency certification, and/or professional certification programs are also job knowledge tests. Licensure and certification are both types of credentialing - the process of granting a designation that indicates competence in a subject or area. Licensure is more restrictive than certification and typically refers to the mandatory Governmental requirement necessary to practice in a particular profession or occupation. A passing score on a job knowledge test is typically a core requirement to obtain a professional license. Licensure implies practice and title protection. This means only individuals who hold a license are permitted to practice and use a particular title. For example, to practice law, a law school graduate must apply for admission into a state bar association that requires passing the bar licensure examination. Certification is usually a voluntary process instituted within a nongovernmental or single Governmental agency in which individuals are recognized for advanced knowledge and skill. As with licensure, certification typically requires a passing score on a job knowledge exam.
