GREG APPLEGATE, Ph.D., MBA
Director and Treasurer
Greg Applegate, PhD, MBA is the Chief Science Officer for the National Registry of Emergency Medical Technicians where he spends his time trying to perfect entry level certification examinations and encouraging EMS research.
Greg began his post military career as a high school teacher and became interested and concerned about testing with the implementation of the No Child Left Behind Act. Unable to find answers from his administrators, Greg began working with psychometric faculty, eventually leaving secondary teaching to pursue a graduate degree in educational psychology. He found some of his answers while in graduate school (and a great many more questions) and has made it his life’s work to create examinations that are valid, reliable, and fair, and to ensure the results are used responsibly.
Greg has worked on a wide range of projects including serving on the Institute of Credentialing Excellence’s accreditation guidelines review committee, the linguistic and cultural translation of a certification examination, developing technology enhanced items, developing a clinical judgment performance examination, and launching live remote proctoring. In addition to examination issues, Greg maintains his passion for education by researching and presenting on effective and efficient teaching and learning.
