Topgrading is a corporate hiring and interviewing methodology that is used to identify ideal candidates for a particular position. In the methodology, prospective employees undergo a 12-step process that includes extensive interviews, the creation of detailed job scorecards, research into job history, coaching, and more. After being interviewed and reference-checked, job candidates are grouped into one of three categories: A Players, B Players, or C Players. A Players have the most potential for high performance in their role while B and C Players may require more work to be successful. The methodology has been used by major corporations and organizations like General Electric, Lincoln Financial, Honeywell, Barclays, the American Heart Association, and others.
