As part of an ongoing project, researchers created a formative speaking assessment tool. Research suggests a clear and succinct rubric is critical to any speaking assessment in the EFL classroom. The project’s analytic rubric helped first-year university students practice and improve their speaking skills. Though learning outcomes were achieved, the evaluation results of the previous cohort tended to range toward the high end. This prompted researchers to review the rubric. Research questions: 1) How did editing and revising the rubric affect student results? 2) How did editing and revising the rubric increase student confidence? This study collected data from student grades and surveys. The findings showed that after introducing the newest version of the rubric, student grades were centered around the average, expected results. Researchers concluded that the use of the revised rubric improved students’ English-speaking skills and confidence.
