Reliability assesses the extent to which variations in test scores reflect true differences in ability between people (on the construct being measured) rather than random errors in measurement.

Test-retest reliability assesses the extent to which the tool produces consistent scores when used on two different occasions.
The test-retest reliability coefficients for the traits of 27 FORTE Personality Assessment range from 0.40 to 0.85.

Additionally, the internal consistency reliability coefficients for the assessments were found to be ranging from 0.3 to 0.8. This assesses the extent to which all of the items in a scale are measuring the same underlying construct or trait.

Validity assesses the degree to which a scale measures the construct that it claims to measure. Convergent and Divergent validities have been used to assess the validity of the 27 FORTE Personality Assessment. Convergent validity checks whether scores on two different tests measuring the same construct are significantly correlated. Divergent validity checks whether scores on two different tests, which measure constructs distinct from each other, show insignificant correlation.

The coefficients of convergent and divergent validity for the 27 FORTE Personality Assessment range from 0.3 to 0.4, and 0.4 to 0.5 respectively. Predictive validity was also computed. Predictive validity is established by comparing an individual’s performance on an assessment to his/her future performance on a set of predetermined criteria.

To establish predictive validity, a pool of candidates was identified. For these candidates, independent behavioral ratings on all traits from managers or immediate stakeholders were recorded. The predictive validity coefficients for the 27 FORTE Personality Assessment ranged between 0.3 and 0.5.

Norm groups are available for 3 levels - Junior, middle, and senior. Normed on a sample of 7400+ respondents across different geographies - India, USA, Europe and Southeast Asia (representative sample with different age, gender, job level, occupations)
