An e-assessment project, published in the mid-1980s, conducted an examination of both test validity and test reliability using a personal computer (Apple II) for administering the Peabody Picture Vocabulary Test-Revised (PPVT-R) compared to a traditional paper and pencil administration.
Jillian M Bellinger conducted a study to test the reliability and validity of the story retell task (RTF). [6] In this study, examiners scored retells in live time and from a digital recording. Results indicated that there was a significant difference, with a large effect, between retells scored in real time verses those scored from a digital ...
The validity of an assessment is the extent to which the assessment measures what it claims to measure. Many other studies have demonstrated the reliability and validity of STAR Reading, [2] STAR Math, [3] and STAR Early Literacy. [4] Additionally, many studies have differentiated between STAR assessments and other tests of similar skills. [5]
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.
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".

Since there is overlap in skills tested between the high end of level I and the low end of level II, this provides another estimate of the reliability of both. On Reading and Spelling, split-half reliabilities ranged from .88 to .94 for different age groups; on Arithmetic they ranged from .79 to .89.
The considerations of validity and reliability typically are viewed as essential elements for determining the quality of any standardized test. However, professional and practitioner associations frequently have placed these concerns within broader contexts when developing standards and making overall judgments about the quality of any ...
READ 180 was founded in 1985 by Ted Hasselbring and members of the Cognition and Technology Group at Vanderbilt University.With a grant from the United States Department of Education’s Office of Special Education, Dr. Hasselbring developed software that used student performance data to individualize and differentiate the path of computerized reading instruction.
