Inwald Personality Inventory

What is the Inwald Personality Inventory?

The Inwald Personality Inventory (IPI), developed by Robin Inwald, is an assessment designed for screening applicants to high-risk public-safety roles. Its focus is on potentially problematic personality and behavior patterns, rather than a general strengths profile.

IPI and IPI-2

The California POST screening manual (2019) describes the original IPI as a 310-item true-or-false inventory and distinguishes it from the later IPI-2 revision. The revised instrument uses public-safety applicant norms.

Use in public-safety screening

Evidence and interpretation must refer to the specific version. The existence of a screening measure does not mean it reliably predicts every applicant's future performance, or that it is suitable for unrelated occupations. It contributes information to an assessment; a score alone is not a complete judgment of an individual's suitability.
