Q: I often get asked about the evidence behind The Leadership Challenge®, specifically questions like how many people have actually taken the LPI®, etc. Can you provide the most recent data?

A: Among the many factors that set the LPI® apart from nearly every other leadership assessment available today is the rigorousness of the research behind its creation and the ongoing analysis conducted not only by me and my co-author, Jim Kouzes, but by other scholars and researchers around the world. And every year, as new leaders and observers complete the LPI we update the numbers and include the analysis of that new data. Through the end of 2017, here’s the latest information about the use of the LPI:
  • Over 5 million people (leaders and their observers) around the world have completed the LPI since it was first introduced in 1985
     
  • More than 3.5 million responses of these have been completed online; this database of responses serves as the basis of the statistical analysis we conduct to analyze how The Five Practices of Exemplary Leadership® and the 30 leadership behaviors impact leaders’ effectiveness and levels of employee engagement
     
  • Every year, 400,000+ new responses are added to the database and systematic, ongoing empirical analyses keeps the normative nature of the research current and relevant
     
  • 700+ doctoral dissertations and research studies have used The Five Practices of Exemplary Leadership® model and the LPI as a research tool. We also typically publish several academic and practitioner-focused articles annually in such publications as the Journal of Leadership Studies, Academy of Educational Leadership, Leadership & Organizational Development Journal, Harvard Business Review, and Journal of Selling. 
In addition, our internationally-acclaimed bestselling book, The Leadership Challenge, now in its sixth edition, has been translated into 20 languages and read worldwide by over 2.7 million people.

Put this all together and it’s why we are confident in saying that the LPI is one of the most widely used and trusted 360-degree leadership assessment instruments in the world.
