Differentiated assessment is an essential approach in the independent curriculum to
meet the diverse learning needs of each student. This study aims to determine how the
teacher implements differentiated assessment and its benefits and analyze its
effectiveness in supporting learning outcomes, developing students' potential, and
integrating students' learning styles and interests in the assessment process. This
approach promotes more personalized and meaningful learning by allowing the teacher
to customize assessment strategies based on students' needs, interests, and learning
styles. This research was conducted at SMAN 5 Banjarmasin, one of the driving
schools implementing the independent curriculum. The researcher observed the
assessment of learning activities and interviewed an English teacher and twenty
students from four classes. The research was conducted through a case study method
with data collection techniques in the form of observation and interview, providing data
on how the teacher implements differentiated assessment in English within an
independent curriculum. The interview results provide data on the benefits of
implementing differentiated assessment from the perspective of the teacher and
students. The results show that differentiated assessment can increase students' active
participation, conceptual understanding, and learning motivation and strengthen
students' engagement by recognizing their learning style preferences and interests. In
addition, this approach allows the teacher to implement more effective targeted actions
to support the development of students' full potential. The implementation of
differentiated assessment within the independent curriculum offers the opportunity to
create a more inclusive, personalized learning environment that is adaptive to each
student's unique needs.
