Undergraduate students’ performance has been extensively studied to identify the critical components in effective teaching and learning pedagogies. This study aims to determine whether the teachers’ practices and implementation of Classroom Assessment Techniques (CAT) enhanced students’ performance in Accounting Principles’ courses and assess students’ perceptions concerning the impact of English language proficiency (EP) and the availability of Saudi-centric textbook materials on students’ performance. Additionally, this study employed the questionnaire survey approach to gain insights into accounting undergraduates’ perceptions of academic performance in Accounting Principles courses. As most students were found to be underachievers, the study outcomes led researchers to propose active learning approaches using CAT as an initiative towards improving students’ performance in benefitting the university and positively transforming the teaching and learning environment.
