Background: Efficiently assisting students in achieving core competencies is a crucial
aspect of nursing education. Team-based learning is one strategy that has been suggested to enhance
nursing education (TBL). Aim: to assess the effect of team-based learning on core competencies
and cognitive engagement of maternity nursing students. Design: A true experimental study design
was applied Setting: This study was implemented at the faculty of nursing in Beni-Suef University.
Subjects: A purposive sample composed of 160 out of 274 third years maternity and newborn
health nursing students in their 1st
 semester of the academic year 2023-2024. Tools: The data were
gathered using three instruments; a structured interviewing questionnaire, core competencies
instrument, and cognitive engagement instrument. Results: revealed that, within control group
&study group, pre-intervention, there was insignificant difference in total core competencies and
cognitive engagement. While post intervention, there was an improvement that is statistically
significant in the total competencies and cognitive engagement in study group (p= 0.037*)
compared to the control group. Conclusion: The TBL program was successful in enhancing the
critical thinking, self-leadership, problem-solving skills, communication skills, and finally cognitive
engagement of nursing students. For this reason, TBL is seen to be a helpful learning and teaching
technique that can optimize the learning outcomes for maternity nursing students in programs for
women's health nursing. Recommendation: The results imply implementing longitudinal studies to
assess the long-term impact of TBL on students' clinical performance, retention of knowledge, and
professional development after graduation.
