This research investigates the effect of DA on increasing students' English-speaking performance as Foreign Language (EFL) learners in university. The research used a qualitative method involving four university learners from different faculties in the first semester. The participants received the same treatments through tests, self-evaluation, feedback and knowledge expansion, and semi-structured interviews. The instruments used in this research aim to analyze the learners' non-fluency and mastery problems. The finding showed some positive attitudes of DA on EFL learners’ speaking performance. In interviews, learners showed positive experiences and attitudes toward DA since it served them as a comfortable, structured, practical, and meaningful platform to recognize their speaking behaviours, weaknesses, strength, and needs. Furthermore, it also helped them to get objective feedback with less anxiety. The researchers conclude that DA can be applied as a primary alternative assessment to increase English speaking performance.
