Our Mission

Together, We Spark Transformative Experiences in People’s Everyday Lives

TTI Success Insights applies a multi-science approach to an ever-evolving suite of tools that support the employee journey. This commitment to continual improvement aligns with the American Psychological Association’s (APA) philosophy and methodology for assessment development, implementation, and validation.

Through the Science of Self®, our suite of assessment tools help individuals, teams, and organizations develop to become the best they can be.

How It All Started

Chairman Bill J. Bonnstetter and his son, Dave Bonnstetter, founded Target Training International, Ltd. in 1984. Our assessments quickly became an essential aspect in the businesses of thousands of independent consultants and business coaches.

Our company’s history is storied and full of accomplishments — and we’ve touched millions of lives along the way.
