World’s Largest Independent Petroleum Refiner Amazed by The JDL Group’s Accuracy

Principals of the JDL Group have been used by Valero for hiring/selection, leadership development, and merger and acquisition support for over 15 years. Pairing assessments with business requirements, The JDL Group has been able to accurately and reliably predict success at a 90 percent or better rate – providing accurate prediction around the human side of the business. The JDL Group also created a customized Situational Judgment Inventory for use in Operator selection, training and development work.


“After working with both of these individuals who were assessed using The JDL Group processes, I am amazed (though I shouldn’t be) in just how dead on the assessment results were and how well they were interpreted by the JDL Group. The licensed Industrial/Organizational Psychologists at The JDL Group truly are gifted.”
