Reliability

PAC's assessment was built from the ground up and utilizes the most recent advances in IO Psychology Research to ensure the highest reliability and predictive ability.

Introduction

Reliability is the overall consistency of a measure. Reliability is usually evaluated using Cronbach's α (alpha), a metric that reflects the consistency of results across items within a scale. In published assessments, a Cronbach's α of .7 is considered minimally acceptable, .8 is considered good, and .9 is considered excellent. Ideally, all scales on an assessment should have a Cronbach's α of .8 or higher. In real life, few assessments meet that goal.

All of Sokanu's scales have Cronbach's α above .8. The average reliability is .88, and the minimum is .82. This level of reliability suggests that Sokanu's assessment is suitable for use in both personal and high-stakes testing.

Cronbach's α (alpha) is a measure of reliability. Higher "value"s are better. Ideally, all scales on an assessment should have an α of .8 or higher. In real life, few assessments meet that goal.
