The aim of this thesis was to investigate the effect of using performance assessment tasks on developing EFL listening comprehension skills among preparatory stage pupils. The instruments of the research included: a list of listening comprehension skills and a pre- post EFL listening comprehension skills test. In addition, using performance assessment tasks were prepared. The participants of the study included (60) pupils chosen from El Shaheed Prep School, El Basateen Directorate, Cairo Governorate in the academic year 2017-2018. They were divided
into two groups: The experimental group (n=30 pupils) and the control group (n=30 pupils). The experimental group received instruction using the performance assessment tasks for developing their listening comprehension skills whereas the control group pupils were exposed to traditional assessment. The data was statistically analyzed using nonpaired samples t- test and the effect size was calculated. The results showed that there were statistically significant differences between the mean scores of the experimental group and control group in the post measurement in favor of the experimental group students in the overall listening comprehension skills and in each sub skill (critical comprehension, inferential comprehension and literal comprehension). It was concluded that using performance assessment tasks affected on
developing listening comprehension skills among preparatory stage pupils.
