This study aims to prove whether Peer Assessment can improve students'
understanding and application of writing in grammar. This study investigates peer
assessment as a learning strategy, focusing on students' ability to apply writing
knowledge to descriptive texts. To address this, the researcher used a quasi�experimental design. The population of this study was eleventh-grade students at
Untad Palu Lab School. The researcher took class XI Mipa 1 (18 students in the
experimental group) and XI Mipa 3 (18 students in the control group) as samples by
using the purposive sampling technique. This study utilized a pre-test and post-test,
with data analysis conducted using the Mann-Whitney test (SPSS 24). The Mann�Whitney test was employed to compare two independent groups with ordinal or
interval data that were not normally distributed. The results showed that the test
statistic was 0.000, which is less than 0.05, which indicates that the null hypothesis
was rejected and the alternative hypothesis was accepted. The findings suggest a
significant difference in learning outcomes between the experimental and control
groups. It was concluded that peer assessment had a significant influence on students'
learning outcomes in writing descriptive text with correct English grammar. The
results of this study provide valuable insights for students, teachers, and future
researchers, highlighting the potential of PA to improve English as a Foreign
Language (EFL).
