TTI SI offers our most popular assessments in 40 languages representing more than 90 countries.

Your Language Matters
Your brain connects to language at different levels. When you take an assessment in your native tongue, your brain makes the strongest connection. We locally translate our assessments to capture even the most subtle language nuances and variations, providing the most accurate assessment results.
Vanessa Boettcher, vice president of TTI SI International, speaks four languages. Her brain scan image (pictured) shows the strongest connection to the word enthusiastic with her first language, Spanish.
“Even though I have spoken English during my entire adult and professional life, my report is still most accurate when I respond in my native tongue.“
– Vanessa Boettcher, Vice President of International Distribution, TTI Success Insights

After 20+ years in the market, TTI Success Insights produces the highest quality assessment tools worldwide, while creating and maintaining international relationships that share a truly global brand, which ties us all together.
