Our History

The employers who hire your graduates have used Wonderlic to test incoming employees for over 75 years.


  • By combining ease of use with technical integrity, Wonderlic first set the standard for workplace testing when the Wonderlic Personnel Test (WPT) made its debut in 1937.
  • By WWII, the U.S. Navy was depending on the WPT to help select the best possible candidates for pilot training and navigation.


  • By the 1950s, the WPT was among the country’s most widely used and respected employment assessments with over 2 million administrations annually.
  • During the 1960s, Wonderlic continued its efforts to help employers make better, more informed employment decisions by publishing a wide variety of knowledge, skills and ability tests.


  • Wonderlic developed the Scholastic Level Exam (SLE) and established educational program-specific admissions scores throughout the 1970s.
  • During that same decade, Hall of Fame NFL Coach Tom Landry of the Dallas Cowboys began using the WPT to forecast player performance, a phenomena that continues today.


  • Throughout the 1990s, Wonderlic developed and perfected a model for establishing and assessing candidate qualifications for all 1,110 job titles in the US Department of Labor Occupational Network (O*Net) database.
  • When the U.S. Department of Education (ED) established regulations requiring career colleges to demonstrate students’ “ability to benefit” from occupational training programs, Wonderlic provided a comprehensive solution that was approved in 1991.
  • In 2004, Wonderlic developed the Wonderlic Basic Skills Test (WBST) in response to new ED regulations limiting Ability-to-Benefit tests to those specifically measuring basic math and verbal skills.

2010 and Beyond

  • In 2010, following approval by the ED, the Wonderlic General Assessment of Instructional Needs (GAIN)® improved the efficiency, transparency and effectiveness of adult basic education and workforce development outcomes.
  • Leveraging its unparalleled expertise in both educational and employment testing, Wonderlic initiated the development of course and program mastery assessments: the Direct Assessments of Learning Outcomes (DALO) in 2012.
