psychometrics

McCarthy has an expertise in 'psychometrics' , assessment and research methods, and a longstanding commitment to education in psychology.

As a particular discipline, 'psychometrics' provides methodologies for constructing measurement tools and frameworks for testing whether such tools achieve expected objectives.

The longest shadow hanging over 'psychometrics' - the measurement of intelligence - comes from The Bell Curve, the 1994 book on genetic influences written by Richard Herrnstein and Charles Murray.

‘For a hundred years, 'psychometrics' have done a great job of identifying high ability in many domains, but we haven't spent as much time identifying underlying mechanisms responsible for why people test this way,’ says O'Boyle.

Although this was necessary, due to the lack of pre-existing measures in the field, these measures lack established 'psychometrics' .

There are the 'psychometricians' , who look at the statistics and biology of IQ and try to determine how much of intelligence is innate.

For 'psychometricians' , the emergence of item response theory has introduced new rules for measurement that have a number of advantages over older methods.

Teachers need not become psychologists or 'psychometricians' to understand the purpose, advantages, and limitations of test scores.

Many 'psychometricians' recognize multiple separate categories of intelligence.

Among contemporary 'psychometricians' , the term construct validity encapsulates all that has historically been meant by validity and its many qualities or criteria.
