Criterion Related Validity Coefficient

Coeffecient representing usefulness of predictor for predicting criterion outcomes; uses correlation. Higher correlation means higher test scores = better performance. Increased confidence in selection procedures.


Taylor and Russell use of validity coefficient

Usefulenss depends on selection ratio and base rate of success. When validity coeffecient is moderate to high, it is useful for informing selection decision when base rate is moderate and selection ratio is low.


Selection ratio

Number of openings per number of applicants


Base rate of success

Unscreened employees who are currently successful on the job


When is validity coefficient not useful

When the base rate of success is very high or very low.


Reliability coeffecient

A correlation that reflects the consistency and stability of a measure, over time, across equivalent forms, or among internal items.


Incremental validity

Refers to the additional predictive validity that can be gained by adding more measurement devices to an assessment program.


Validity generalization

Refers to the extent to which a validity established in one setting with one sample can be generalized to another setting and sample.


Adverse Impact

A legal term that refers to the potentially unintentional discrimination against a protected group (usually minority racial groups and women) due to the use of a selection or placement procedure. (less than 80%)


Reliability coefficient - calculation

Used to assess the consistency or a measurement of instrument or procedure, internally, with different forms, or across time.


Reliability Coefficient - statistic

Computed to asses the consistency in judgment of 2 or more human raters engaged in the same rating task. (i.e., test-retest, equivalent-form, split-half, inter-rater.



Coefficient of stability, measurement given to same group at two different times, risk of contamination from carryover of first test to second test.



Coefficient of equivalence, parallel forms of the instrument are given to the same group at the same time; difficulty generating two forms


Internal consistency

Split-half or Chronbach's alpha; correlate first half to second half or correlate every other item; widely used in I/O



Correlate scores of various raters; important in I/O for job analysis ratings and employment interviews


Quality Assurance (QA)

Planning and processing moves undertaken by an organization to ensure products/services serve intended purposes (which are defined by users of the product or services.


Process to ensure QA

Assmts conducted over time to determine reliability; controlling and monitoring materials, processes, mgmt., and personnel.


Quality Control QC

Finding defects/errors before customer presented with product; based on organizational standards and expectations, not external feedback; QC can inform QA process


Total Quality Management TQM

Attempting to embed QA in all aspects of organization; assigning responsibility for QA to organization's production, process, and distribution members. Improving quality and meeting demands.



Methods & procedures used to evaluate & understand individuals in the workplace. That outcome is used to make decisions about individual performance, skill and training levels, aptitude, as well as organizational processes.


Contextual performance

Bxs performed by an employee that are not part of his or her regular tasks, but that reflects positively on the organization or otherwise assist the organization. AKA organizational citizenship.


What happens when selection ratio is high

This indicates that most applicants will be hired, including those that will be unsuccessful.


What happens when selection ratio is low

Indicates few applicants hired per number applied, minimizes inclusion of unsuccessful candidates


What happens when base rates are high

Indicates that most employees are successful, thus most candidates will be as well and the test won't be necessary or helpful.


What happens when base rates are low

Indicates the test won't discriminate those who won't be successful


What happens when base rates are close to .50?

Validity coeffecients will be best able to determine success of the candidate.


What is the best scenario regarding selection ratio?

Selection ratio is low, base rate is moderate, then even lower validity coefficients are informative.


Ways to mitigate adverse impact

Separate cutoff scores for different groups, banding, selection of predictors determined to be valid and reliable.



using ranges of scores where all scores within a range are considered equivalent


Criterion contamination

Occurs when the assessment on the conceptual criterion (e.g., job performance) is made not only by relevant actual criteria measures, but also in terms of actual criteria that could be considered extraneous.
