Sound & Effective Practices

PSI takes on the rigorous, scientific processes involved in test development to enable the systematic collection, analysis, and interpretation of information about work in order to make a valid interpretation of a candidate’s knowledge. Our Science Advisory Board helps to ensure that our psychometric practices are sound and effective. We have extensive experience in all phases of test development:

  • Job Task Analysis
  • Test Design and Content Specification
  • Test Development and Form Assembly
  • Item Authoring and Banking

Test Validation

Validity is a measure of effectiveness. Validation studies are performed to ensure the right test or assessment is used in the right applications to ensure you make successful hires or decisions involving employment, admissions, training, or job placement. The more accurate an exam is, the more it appropriately measures what it was designed to measure. And the more it produces reliable and consistent results over time.

From a legal perspective, a selection procedure (e.g., a pre-employment test) is valid if it can be proven by an employer that it is job-related and necessary to determine job fit and ability to perform a specific role. For instance, leaders need the ability to coach and develop others, while most IT candidates need networking or programming skills and sales people need the ability to persuade. PSI has many years of experience validating testing processes and content to ensure your employees and candidates perform the job properly and/or excel.
