This study aims to explore teachers’ perceptions and practices of the use of rubrics in assessing students’ learning in the context of higher education institutions in Gilgit-Baltistan. A case study method of inquiry within a qualitative paradigm was adopted to collect the relevant data through semi-structured interviews from three purposefully selected teacher-educators (instructors) and six student-teachers (prospective teachers) of semester III and IV from one of the colleges of education. The data were analyzed through thematic analysis and following themes were emerged: (1) the importance of assessment rubrics in teaching and learning processes, (2) effectiveness of rubrics in assessing teaching and learning, (3) coconstruction of assessment rubrics by student-teachers and teacher-educators, and (4) the challenges for student-teachers and teacher-educators in developing and using of assessment rubrics. From the discussion on the emerging themes, it is concluded that (a) use of assessment rubrics makes assessment process more meaningful to both teacher-educators and students-teachers; and (b) use of rubrics makes student-teachers and teacher-educators more focused on their purpose of teaching and learning outcomes. It is recommended that teacher-educators in teacher training institutions should use rubrics to assess prospective-teachers so that they, after completing their degree programs, would use similar techniques in their respective schools to assess their students’ learning outcomes effectively.
