Auditing hotels involves a unique set of tasks distinct from other types of audits. Certifications may encompass various departments, including Human Resources, Purchasing, Legal, Food & Beverage (F&B), Maintenance, Excursions, Housekeeping, Front Desk, Training, and Meetings, Incentives, Conferences, and Exhibitions (MICE).   To effectively conduct these audits, an auditor must possess extensive knowledge of hotel operations. This includes an understanding of the dynamics between services and the complexities of both horizontal and vertical management. The primary role of the auditor is to gather evidence to ensure that the hotel complies with established standards. While some evidence can be visually assessed, many aspects require in-depth discussions to accurately evaluate the level of commitment from the staff. This necessitates strong interpersonal skills to gain the trust of the team and elicit an honest portrayal of the hotel's operations. The technical component of the audit is crucial, as it constitutes a significant portion of sustainability certifications for hotels. Auditors must acquire knowledge in areas such as HVAC systems, thermodynamics, water and wastewater management, energy efficiency, health and safety protocols, and chemical storage. Currently, there is no academic curriculum that provides the comprehensive knowledge and skills required for hotel auditors. As a result, many auditors must rely on self-directed learning or their personal experience within the hospitality industry to conduct effective audits. With the increasing demand for hotel certifications, there is a pressing need to establish structured support for auditors specializing in the hospitality sector. The credibility of certifications rests on the qualifications of the professionals conducting the audits. It is essential that auditors are equipped with the necessary expertise to meet and exceed the expected standards.
