English is widely used in Thailand's tourism industry by tourism-related personnel for communication, negotiation, and transactions with foreign tourists. This study aimed to examine the problems and needs relating to improving English language skills among 150 tourism-related personnel in Phang Nga province and the communication problems experienced by 50 foreign tourists. The researchers employed questionnaires and interviews to collect the data and analyzed the collected data using percentages, means, standard deviations, and content analysis. The findings indicated moderate English-language problems among tourism-related personnel in Phang Nga (Mean = 3.39, S.D. = 1.04) and confirmed by foreign tourists (Mean = 3.40.S.D. = 0.68). The most problematic area was writing skills (Mean = 3.57, S.D. = 1.18), followed by reading skills (Mean= 3.42, S.D. = 1.04). However, it was also observed that tourism-related personnel in Phang Nga province needed to enhance their listening skills (Mean = 3.60, S.D. = 1.09), followed by speaking skills (Mean = 3.53, S.D. =1.08). The majority of personnel (83.3%) expressed a desire to attend English training. The study suggests developing an English training program tailored to the specific needs of tourism-related personnel to enhance their English proficiency for effective communication at work.
