Criterion-related Validity

Criterion-related validity assesses how well the assessment predicts or correlates with specific criteria or outcomes. It involves comparing assessment scores with performance measures, such as job performance ratings or supervisor evaluations. Criterion-related validity can be further divided into two subtypes: concurrent validity and predictive validity.

  • Concurrent Validity: Concurrent validity establishes the relationship between assessment scores and current performance measures, allowing HR professionals to evaluate the assessment's effectiveness in predicting current job performance.
  • Predictive Validity: Predictive validity examines the correlation between assessment scores and future job performance, enabling HR professionals to assess the assessment's predictive power.

Construct Validity

Construct validity assesses the extent to which an assessment measures the intended construct or psychological attribute. It involves examining the relationships between the assessment and other related constructs, theoretically deriving hypotheses, and conducting statistical analyses to support the validity of the assessment.

Reliability of Psychometric Assessments

Reliability ensures that the assessment results are consistent and stable over time, regardless of the conditions or individuals administering the test. Three main types of reliability are test-retest reliability, internal consistency reliability, and inter-rater reliability.

Test-Retest Reliability

Test-retest reliability measures the consistency of assessment results when the same individuals are tested twice or at different points in time. It assesses the stability of scores over time, assuming that the construct being measured remains stable.

Internal Consistency Reliability

Internal consistency reliability assesses the degree to which the assessment items within a test are consistent and measure the same construct. It measures how well the items correlate with each other and can be evaluated using statistical methods such as Cronbach's alpha.

Inter-Rater Reliability

Inter-rater reliability ensures consistency in assessment results across different raters or assessors. It assesses the degree to which different assessors obtain similar results when evaluating candidates. Inter-rater reliability is especially important for assessments that involve subjective judgments or observations.

Having a clear understanding of the validity and reliability of psychometric assessments is crucial for HR professionals and hiring managers. It enables them to confidently interpret and utilize assessment results during the selection process.
