TTISI's assessments are scientifically validated. They are well-written, comperhensive, and easy to understand. They provide my clients with great insight, and help me as an executive coach identify areas where we can work together to improve performance and goal attainment. The staff at TTISI is fantastic - they are all well versed on their own tools. They are helpful and just the nicest people you might encounter and work with. Their reports and platforms have been refreshed, and the company continues to invest in their intellectual property and platforms. They work hard to help you be successful with their tools and in developing your assessment-related business.

The tools and reports are very customizable for organizations and consultants using them. They have a very responsive support team that works with users to create solutions. They have a strong international footprint and availability in many different languages. They run ongoing validity and reliability studies on their tools and publish the results publicly (the great majority of competitors don't do robust studies or if they do, the results are not published for the public, only for proprietary users).

The ease of use with the website, links and report options.
