Validation Studies

Validation is the process of measuring the accuracy, reliability, and consistency of a testing instrument. At PeopleKeys, we never launch a product without first gathering practical and theoretical research to validate it works as advertised. We have conducted countless internal studies, and have worked closely with independent agencies to run specialized reliability and validation tests to confirm the results of our research.
