Test Characteristics

Validation Documentation

The Polaris testing system includes both homogeneous and heterogeneous components. The “elements” of the system consist of homogeneous constructs developed to tap up to (a) 18 personality components, (b) 2 reasoning components, (c) 3 arithmetic comprehension and measurement components, (d) 2 perceptual and detail-oriented components, and (e) 3 attitude and belief components.

A strength of the system, however, is that these sophisticated “elements” are practically invisible to users. Instead, they are combined into heterogeneous predictor dimensions (e.g., Ease of Supervision, Working with Others, Quality and Productivity Orientation) that communicate easily to managers, HR professionals, and other practitioners.

The result is a set of predictor scores that satisfies the standards of test and measurement professionals (scales that have Cronbach’s Alphas of at least .70) and provides feedback to users in general business terms, as well.
