Your Key to Unlock the Science of Self®

You have unique talents and skills in which you are often unaware. You can reveal and harness those talents using the Science of Self.

When you use our assessments, you uncover the how, what and why of human interaction. You measure behavior, motivators/driving forces, emotional intelligence (EQ), acumen and skills to quantitatively reveal the whole person.

Then you translate your knowledge to others in real and powerful ways.

Our pursuit of the Science of Self has made us both a pioneer and a trailblazer in the assessment industry for over 30 years.

Experience the Science of Self®

The Science of Self is best demonstrated by an assessment that will unveil how you behave and what drives you.

Research Beyond Statistics

The popularity of assessments has increased in recent years. Luckily for our TTI SI associates we’ve been researching and validating our assessments with data norming and rigorous data analysis for over three decades.
