For directors on boards, few moments could be more satisfying than finding the right CEO—a leader who can shift the organization into high gear, set the strategic vision, and make a long-term impact.

Candidates who scored the highest on the CEO assessment averaged one year and three months longer as CEOs than those who didn’t.
