The study aimed at identifying the core language skills regarded as most significant in the academe and eventually in the workplace among engineering graduates. The study surveyed tertiary students to identify their perception of the skills needed upon graduation, together with the kind of instruction that would improve and progress the said skills. An interview among chosen professors was also conducted, together with in-class observations to provide more insights on the prerequisites that engineering graduates need to succeed, starting from job applications to full immersion in the field. The qualitative method applied showed that the most significant skills an engineering student/practitioner must acquire according to the survey among students are a) above-average writing and writing laboratory instructions and b) above-average listening skills that lead to an active speaking dialogue. The classroom observation shows that students are not inclined to participate in discussions and the interviews with the professors reveal that engineering students are not very competent orally and thus, speaking in their native language Taglish (Tagalog + English) should be allowed at the beginning until they become proficient in English. A pedagogical implication was provided together with a recommendation in addressing the possible gaps in the curriculum and methodologies.
