Driven by professional guidelines 

Our assessments are developed following recognized psychological standards and guidelines, including the American Psychological Association (APA), the Society for Industrial and Organizational Psychology (SIOP), and the International Test Commission (ITC). These guidelines provide a framework for test construction and the proper use of assessments. The Predictive Index provides well-researched, valid and reliable assessments which can help support clients’ legal compliance with the EEOC and the Uniform Guidelines on Employee Selection Procedures. In addition, the Predictive Index, to our knowledge, has never been successfully challenged in court, and we offer validation services for our clients that are necessary to establish the job-relatedness of our assessments.Science Validity Logos_Vector.svg

How our assessments are developed

With more than sixty years of science under the belt, an assessment provider may be happy to rest on their laurels and bask in their past accomplishments. But at PI we put our dedicated I-O psychologist, psychometrician and statistics guru to work to ensure our clients benefit from the latest research.

Here is a peek behind the curtains at how our assessments are built through science (in their own words of course!).

Field Testing and Form Development.

Adjectives for our form were field tested with results from more than 136,000 people and went through content review, psychometric review, and fairness review. The assessment was then given to a global norm group of more than 10,000 people. Norm tables and scoring models were updated and verified before finalizing the form and sending it through a multilevel translation process and regional review.

Confirming Construct Validity

The field test data was used to conduct a content validity analysis, reliability studies, differential item functioning analyses, a check of factor unidimensionality using exploratory factor analysis, and a check of the entire factor model with a confirmatory factor analysis, which also demonstrated improved validity loadings over the previous version of the assessment. A convergent validity analysis was also conducted to show that scores correlated as expected with the previous version of the assessment, as well as with a variety of other personality scales.

Verifying Criterion Validity

PI has hundreds of individual criterion validity studies, as well as some meta-analytic criterion validity studies, so a new meta-analysis was conducted with the new form of the assessment to demonstrate its relevance to job performance. More than 1,200 respondents in 26 job roles from 14 companies participated in the new criterion validity study. Job roles were grouped based on similarities (e.g., management roles), and meta-analyses were run to estimate corrected correlations between factor scores and managers’ ratings of employees’ job performance, compliance, initiative, and cooperation.
