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.
