03 Assessment Instruments

The tools GPS uses and why we chose them

Personality · Leadership Potential

Hogan Assessments

The HPI, HDS, and MVPI together form the most comprehensive picture of how a leader behaves at their best, how they derail under pressure, and what core values drive their decisions. GPS uses Hogan in executive coaching and succession readiness work.

Used for: Executive coaching, succession planning, high-potential identification

Adaptive Leadership · Blanchard Authorized

Situational Leadership (SLII®): LBAII & LAPII

The Leader Behavior Analysis II measures leadership style flexibility and effectiveness. The Leader Action Profile II measures directive and supportive behavior patterns. Both anchor the GPS Manager Effectiveness Program and the standalone Situational Leadership One-Day Workshop.

Used for: Manager Effectiveness Program, SLII One-Day Workshop

Behavioral Style

Everything DiSC

A practical, highly accessible behavioral style assessment that builds self-awareness and communication effectiveness across teams. GPS uses DiSC in cohort programs where broad participation and ease of application matter more than deep individual profiling.

Used for: Team workshops, new leader onboarding, manager programs

Emotional Intelligence

MHS EQ-i 2.0

The world's most widely used emotional intelligence assessment, measuring 15 competencies across self-perception, self-expression, interpersonal skills, decision-making, and stress management. Highly actionable for coaching debrief conversations.

Used for: Emerging leader programs, manager development, coaching debrief

Conflict Style

Thomas-Kilmann Conflict Mode Instrument (TKI)

35+ years of validation data behind the five-mode conflict framework. GPS uses the TKI in standalone conflict workshops and as a companion to team effectiveness engagements. Each participant completes the online assessment before the session and brings their results.

Used for: Conflict workshops, team effectiveness, manager development

Competency Modeling

Korn Ferry Leadership Architect

The framework GPS uses to build competency models and align individual development to organizational strategy. The Korn Ferry research base connects behavioral competencies to business outcomes — making it the bridge between assessment data and CHRO-level conversations.

Used for: Competency model design, program alignment, succession frameworks
