About Validity
The RGi psychometric and behavioral assessments instruments have undergone independent review for
validity and reliability and have met all industry standards, including
- Adequacy of the items
- Theoretical framework of the intended measures
- Statistical difference among each of the types for establishing discriminant separation
- Stability of the inventory over time
- Statistical convergence and divergence of each behavior scale
- Measuring of the theoretical construct
The Ryan Group's CenterMark, MatchPoint, and WorkingStyles assessment instruments have been determined to be without bias across ethnic boundaries, gender, and age groups.
The reviewing project lead was professor Rodney Erakovich, Ph.D.
