The Gatekeepers™ is based on the personality profiling system known as the Humm Wadsworth. This system is used exclusively throughout Australia, in an expanded and more general format, by Chandler & Macleod Consultants Pty Ltd.
The Gatekeepers system was rescaled by the Department of Psychology at MelbourneUniversity. Humm Wadsworth has been used internationally to develop profiles on over 2 million executives - the real gatekeepers of industry.
Exceptional Sales Performance has adopted this material to form the foundation for sales communications programs.
