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".

This charge was most recently renewed in 1996 when CSE successfully competed for the National Center for Research on Evaluation, Standards, and Student Testing (CRESST), receiving a five-year, [clarification needed] $13.5 million grant from the U.S. Department of Education’s Office of Educational Research and Improvement (OERI).

The 2014 edition is the 7th edition of The Standards, and it shares the exact same names as the 1985 and 1999 editions. [3] Technical recommendations for psychological tests and diagnostic techniques: A preliminary proposal (1952) and Technical recommendations for psychological tests and diagnostic techniques (1954) editions were quite brief.
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.
For example, the Nation's Report Card reported "Males Outperform Females at all Three Grades in 2005" as a result of science test scores of 100,000 students in each grade. [14] Hyde and Linn criticized this claim, because the mean difference was only 4 out of 300 points, implying a small effect size and heavily overlapped distributions. They ...
The answers will vary between individuals, but the average answer is probably close to the actual time. In many fields, such as medical research, educational testing, and psychology, there will often be a trade-off between reliability and validity. A history test written for high validity will have many essay and fill-in-the-blank questions.
The development of a psychological test requires careful research. Some of the elements of test development involve the following: Standardization - All procedures and steps must be conducted with consistency from one testing site/testing occasion to another. Examiner subjectivity is minimized (see objectivity next).
Traditionally, attention focuses on whether assessments are reliable and valid. In practice, educational measurement is largely concerned with the analysis of data from educational assessments or tests.
