Utility

• In testing and assessment, Utility refers to the practicality or usefulness of a tool to improve efficiency.
• Utility analysis is a family of techniques entail a cost–benefit analysis designed to yield information relevant to a decision about the

  usefulness and/or practical value of an assessment.
• Expectancy Data - An expectancy table can provide an indication of the

  likelihood that a testtaker will score within some interval of scores on a

  criterion measure—an interval that may be categorized as “passing,”

  “acceptable,” or “failing.”
• Brogden-Cronbach-Gleser formula -It is for the dollar amount of a utility gain resulting from the use of a particular selection instrument under specified conditions.
• Relative cut score may be defined as a reference point that is set based on norm-related considerations rather than on the relationship of test scores to a criterion.
• Fixed cut score is a reference point that is typically set with reference

  to a judgment concerning a minimum level of proficiency required to be included in a particular classification.
• Multiple cut scores refers to the use of two or more cut scores with reference to one predictor for the purpose of categorizing testtakers.
• Multiple hurdles may be thought of as one collective element of a multistage decision-making process in which the achievement of a particular cut score on one test is necessary in order to advance to the next stage of evaluation in the selection process.
• Compensatory model of selection is when an assumption is made that high scores on one attribute can, in fact, “balance out” or compensate for low scores on another attribute.
