Before making an investment, it is important to know that you are purchasing a product that performs how it says it will perform. Our assessments are tested through multiple statistical measures that ensure we meet the required scientific measures with our instruments. Our validity and reliability testing ensures investors that our assessments are accurate, consistent and reliable.
Validity is the extent to which an assessment measures what it intends to measure. There are serious organizational and legal issues tied to the validity of an assessment. Organizations and business leaders who make decisions in accordance with the results from an invalid assessment could face serious financial consequences. Profiles International employs full-time psychologists and psychometricians who conduct ongoing research to ensure that our assessments exceed all employment assessment guidelines. Profiles’ assessments exceed the thirteen requirements set by the Department of Labor for assessments and meets all of the EEOC, ADA, DOL and Civil Rights Act requirements. The validity process involves a thorough analysis and testing of each item in each assessment. We ensure that our instruments are measureable, objective and relevant to success on the job.
Reliability refers to the consistency of test items as selected by test-takers as well as the scores obtained when re-tested with the same assessment on different occasions. There are different types of reliability analysis, but all are concerned with a degree of consistency. The first reliability test measures the consistency of individual test questions. The second reliability test compares the consistency of the test as a whole. Profiles’ instruments meet all of the scientific recommendations for reliability based upon these two tests and other statistical analyses. Our assessments can be used with confidence by businesses all over the world due to the strict guidelines placed on the reliability of the assessments. Executives can invest with confidence knowing that our reports are based on updated measures and statistically valid and reliable scales.
