Self-concept refers to an individual's perception of their identity, abilities, academic achievements, and personal goals. This study examines the self-concept of first-year and fourth-year BSc nursing students, focusing on the differences and growth experienced throughout their academic journey. The objectives were to assess the self-concept levels of both groups and compare the results. The study involved 50 nursing students selected through a simple random sampling technique (lottery method). The data collection tool included two sections: one for demographic variables (7 items) and another comprising 15 multiple-choice questions to evaluate self-concept knowledge. The findings revealed that 90% of fourth-year students had adequate knowledge of self-concept, whereas 63.33% of first-year students scored similarly. Overall, the fourth-year students demonstrated a significantly higher level of self-concept compared to their first-year counterparts, indicating growth and development in their self-awareness and confidence over the course of their studies.
