How do your tools compare to Watson Glaser tests?

There are many differences, but perhaps the most significant is the conceptualization of "critical thinking" upon which the tests are based. All the critical thinking instruments published by Insight Assessment are based on the international multi-disciplinary expert consensus definition of critial thinking articulated initially in the APA Delphi Research Report of 1990.  The conceptualization of critical thinking skills and dispositions was hammered out by a panel of more than fifty participating experts over an intense two-year period.  It is broad, robust, resilient and applicable across the full spectrum of professional fields, academic disciplines, and life/work settings.
