Learners' success in language learning always has implications for curriculum and instruction. Thus, it is important to take into account the kinds of learning experiences that these learners will find helpful in learning English as a foreign language; and, highlight them when planning a curriculum and adapting classroom activities. This study, with 72 first year engineering students, 3 English for Specific Purposes (ESP) teachers of King Mongkut's University of Technology Thonburi (KMUTT) Ratchaburi, and 3 other stakeholders as respondents, aimed to identify the Thai engineering students' linguistic needs and the language skills needed for them to get a job in the future. It also assessed whether the linguistic needs and the language skills required for the students were addressed in the curriculum. Methods used in this study were modified questionnaire, focus groups and semi-structured individual interviews. Findings revealed that students wanted to go abroad and to be successful in their future careers; thus, considered speaking as the most important skill to be developed and should be emphasized in their English classes. Students preferred to learn through engaging classroom activities and strategies, exposure to the language, and use of technology in the classroom. However, the ESP curriculum did not provide these linguistic needs and language skills.
