Criterion-related Validity



BCGi: Adverse Impact & Test
Validation Book Series
Overview: What is Validation?
• Traditionally, it is making sure a selection procedure (i.e.,
  test) measures what it is designed to measure
• In a legal realm, a selection procedure is valid if it can be
  proven by an employer that it is “…job related for the
  position in question and consistent with business
  necessity.”
• Conducting a criterion-related validation study is one
  way to establish job relatedness for a test

Why is this Topic Important to HR/EEO Professionals?

• Why do I need to know about this topic?
  – Validating your company’s tests will lead to a more qualified workforce
    and will help defend against lawsuits
  – Conducting a CRV study will prove—empirically at your specific
    employer and for the specific at-issue job—if and to what extent the test
    is “working”
• What are the key essentials I need to know about this topic?
  – Certain types of tests can only be validated using CRV
  – Both professional and federal validation guidelines exist and are
    important to the process
  – CRV can be used for “calibrating” your workforce
  – CRV studies can reveal if your test is “fair” or “biased”
• What are the consequences surrounding these issues?
  – CRV can generate “expectancy tables” that can directly show the
    monetary value of testing
  – The “start up” cost of a validation case is $30k to $80k
