The Clifton StrengthsFinder assessment was created under the leadership of educational psychologist Donald Clifton. He wanted to identify the skills of the best of the best of the best and to capitalize on them. According to Gallup,
The Gallup Organization, widely known for its polls and employee selection research, developed numerous semi-structured interviews to identify talent that could be enhanced and used to pursue positive outcomes in work and school. In the 1990s, under the leadership of Donald O. Clifton, Gallup developed the CSF as an objective measure of personal talent that could be administered online in less than one hour.
StrengthsFinder, a revolutionary tool for measuring talents, was first introduced to the world in 2001 with the best-selling book, Now Discover Your Strengths. The updated StrengthsFinder 2.0 was later released in 2007 and is consistently (one of) the hottest selling books on Amazon.
