Which type of personal power is based on specialized knowledge or expertise?

• A. Referent Power
• B. Coercive Power
• C. Reward Power
• D. Expert Power

Answer: (D)

Expert power is the type of personal power that comes from specialized knowledge or expertise. People listen to and follow someone because of proven competence in a particular area. In fire service leadership, this could be a officer with deep training in incident command, fire dynamics, or hazard assessment; teammates turn to them for guidance during complex decisions because they recognize and trust their technical judgment. This power stands apart from referent power, which stems from charisma and personal rapport, coercive power, which relies on the ability to punish, and reward power, which comes from controlling incentives. Expert power is strongest when the knowledge is current, supported by credentials and experience, and communicated clearly; if the expertise is questioned or not kept up to date, its influence can decline.
