Abstract Based on the supplementary Drama Curriculum Content III, the research aims to develop a set of performance assessment tasks and the Drama Appreciation Scoring Rubrics (DASR) for a group of 4th grade primary students in the Performing Art class. Through comparing Drama Content III with the National Curriculum in Performing Arts, three learning objectives were identified and transferred into six items on the first draft of DASR and its tasks for the assessment. After execution, the researcher entered the 4th grade classroom to further evaluate the practicality of the assessment tasks and revise the DASR through action research. Finally, three assessment tasks types were developed including “activity-based,” “discussion-based,” and “writing-based” tasks. It was found that each had its strengths and limitations. However, it is suggested that each task need to be preceded with different instructional activities before its use. Through cycled reflections, more details were refined on the DASR including its “Criteria,” “Assessment Reminder” and “Levels of Mastery.”
