This study is aimed at identifying the speaking assessment methods in multilingual English Language Teaching (ELT) in the Philippines. It also determined the perception of the English language teachers towards the effectiveness of the varied speaking assessment practices in the multilingual classroom. The results of this exploratory sequential mixed method study revealed that the speaking assessment methods perceived to be most effective are debates and argumentations, social surveys, task-based language teaching, individual oral presentations, informative speeches, and role plays. Using various assessment methods is encouraged among English language teachers so as to establish a motivating language learning environment in multilingual classroom settings.
