Shortly after beginning his career in industrial psychology and selection, Dr. Hester performed factor analytic research that proved that there is a definite factor structure in work-related abilities and identified the most important ability factors related to job performance.

During this time he interviewed thousands of job applicants and developed and/or validated selection tests for salespersons, secretarial and clerical employees, supervisors, store managers, and truck drivers. These studies resulted in his inventing the Hester Evaluation System, the first computer-assisted vocational evaluation system, now being used across the United States and in Canada, Japan, China, Korea, Hong Kong, Taiwan, Burma, India, Egypt, Jordan, Chile, Colombia, and Trinidad.

Other contributions to organizational performance by Dr. Hester include the Semantic Climate Inventory (SCI) for the assessment of organizational climate and the Menninger Job Analysis System.

His master's thesis and doctoral dissertation involved original research on the psychometric properties of certain psychological tests and apparatus. He taught employee testing and selection at Loyola University for seven years.
