<P> Performance tests are commonly used in workplace and professional applications, such as professional certification and licensure . When used for personnel selection, the tests might be referred to as a work sample . A licensure example would be cosmetologists being required to demonstrate a haircut or manicure on a live person . The Group - Bourdon test is one of a number of psychometric tests which trainee train drivers in the UK are required to pass . </P> <P> Some performance tests are simulations . For instance, the assessment to become certified as an ophthalmic technician includes two components, a multiple - choice examination and a computerized skill simulation . The examinee must demonstrate the ability to complete seven tasks commonly performed on the job, such as retinoscopy, that are simulated on a computer . </P> <P> From the perspective of a test developer, there is great variability with respect to time and effort needed to prepare a test . Likewise, from the perspective of a test taker, there is also great variability with respect to the time and needed to obtain a desired grade or score on any given test . When a test developer constructs a test, the amount of time and effort is dependent upon the significance of the test itself, the proficiency of the test taker, the format of the test, class size, deadline of test, and experience of the test developer . </P> <P> The process of test construction has been aided in several ways . For one, many test developers were themselves students at one time, and therefore are able to modify or outright adopt questions from their previous tests . In some countries, book publishers often provide teaching packages that include test banks to university instructors who adopt their published books for their courses . These test banks may contain up to four thousand sample test questions that have been peer - reviewed and time - tested . The instructor who chooses to use this testbank would only have to select a fixed number of test questions from this test bank to construct a test . </P>
