The validity of a measurement tool (for example, a test in education) is the degree to which the tool measures what it claims to measure. [3] Validity is based on the strength of a collection of different types of evidence (e.g. face validity, construct validity, etc.) described in greater detail below.
Test validity is the extent to which a test (such as a chemical, physical, or scholastic test) accurately measures what it is supposed to measure.In the fields of psychological testing and educational testing, "validity refers to the degree to which evidence and theory support the interpretations of test scores entailed by proposed uses of tests". [1]
Standards for Educational & Psychological Tests states, "concurrent validity reflects only the status quo at a particular time." [3] Predictive validity, on the other hand, compares the measure in question with an outcome assessed at a later time. Although concurrent and predictive validity are similar, it is cautioned to keep the terms and ...
Many psychologists and education researchers saw "predictive, concurrent, and content validities as essentially ad hoc, construct validity was the whole of validity from a scientific point of view" [15] In the 1974 version of The Standards for Educational and Psychological Testing the inter-relatedness of the three different aspects of validity ...
Over the course of 10 years, this work led to the establishment of measurement systems in reading, writing, and spelling that were: (a) easy to construct, (b) brief in administration and scoring, (c) had technical adequacy (reliability and various types of validity evidence for use in making educational decisions), and (d) provided alternate ...
The ACT is an example of this; there is no cutscore, it simply is an assessment of the student's knowledge of high-school level subject matter. Because of this common misunderstanding, criterion-referenced tests have also been called standards-based assessments by some education agencies, [ 3 ] as students are assessed with regard to standards ...
Validity has two distinct fields of application in psychology. The first is test validity (or Construct validity ), the degree to which a test measures what it was designed to measure. The second is experimental validity (or External validity ), the degree to which a study supports the intended conclusion drawn from the results.
Face validity is the extent to which a test is subjectively viewed as covering the concept it purports to measure. It refers to the transparency or relevance of a test as it appears to test participants. [1] [2] In other words, a test can be said to have face validity if it "looks like" it is going to measure what it is supposed to measure. [3]
