Once students are exposed to an international language, they must master four skills, especially listening, speaking, reading, and writing in order to effectively master and use it. Among the above four skills, oral English is probably considered to be one that requires a lot of study and practice time. A large number of students encountered challenges in early phonetic learning. In fact, a decent language acquisition is one of the keys for students to gradually open the door to this magical language. The aim of the study is to evaluate the speaking skill of secondary students at UK Academy School in Ba Ria city, Ba Ria Vung Tau province to investigate whether the students using their language ability through their speaking skill suitably meet the requirements of the school curriculum in terms of their language proficiency and especially the speaking skill.
