My Careertopia is proud to work with our assessment provider Target Training International.

While we focus on helping professionals and businesses use our assessment tools to help them learn more about themselves, find better job fits, hire smarter, or manage teams more effectively; TTI does all the leg work on the research and testing side.

That includes making sure the assessments have been through millions of user tests to make sure the data is accurate and consistent for the variety of DISC and Motivator styles that exist.  Putting the tools through inspections so they meet government standards for using assessments for hiring purposes.  And much, much, more.

Fair warning, much of the validity and research behind the assessments can be a bit technical, so turn back now if you were just here for curiousity’s sake.

On the other hand, if you’re thinking of using these assessments in your hiring and want to make sure the assessments you use are validated and safe, the following should help.

From TTI’s Research Site

While other think tanks have emerged with broad, loud objectives, TTI has been steady and meticulous, continuously producing reliable research that is highly effective and relevant to corporate America. That’s why TTI’s related company, TTI Success Insights, has a network of over 7,000 distributors who use TTI-validated assessments exclusively and provide services to the Fortune 500, and to companies in 90 countries and 40 languages.

Above all else, TTI is committed to constantly improving its assessments and their validity and research. While others in the industry use glossy marketing to sell their products, we rely on data norming, Cronbach’s alpha, structured equation modeling, sampling and rigorous data analysis to guarantee the results business demands. That’s why we’ve been in business for three decades.

To maintain our high integrity in the marketplace, independent statisticians continually run Cronbach’s alpha reliability coefficient. For more details, please email validity@ttiltd.com.
