The School was established in May 1990 in response to growing demands for well-trained hotel personnel in rank and-file and lower middle management categories. According to an industry survey, the workforce in these categories is regularly impacted by high turnover. Various hotel schools have been created in an attempt to address these issues. However, theories have tended to receive more attention than the practical training required for success at operational levels.

OHAP was launched with an emphasis on practical training. Theory is kept to the basics. Seventy per cent of the instructors are highly qualified hospitality industry subject matter experts. The rest are specialists invited from various distinguished institutions.

The courses available include Front Office, Housekeeping, and Food & Beverage (International Cuisine, Traditional Thai Cuisine, Bakery & Pastry, Gastronomy, Restaurant Operations and Bartending).
