The layered curriculum maintains its importance in education as it helps students gradually develop their cognitive levels, supports their academic success, and offers a structured learning process tailored to individual learning needs. This programme contributes to the development of skills such as taking personal responsibility, critical thinking, advanced problem-solving, and achieving academic success, thereby increasing its effectiveness in education over time. This study aims to analyse the results of experimental studies examining the impact of the layered curriculum on academic success through meta-analysis and to identify the effects of moderator variables, including publication type, institution, experimental process durations, and sample size. A total of 41 effect sizes derived from 13 theses meeting the inclusion criteria were included in the meta-analysis. The findings of the study indicate that the layered curriculum has a positive and moderate effect (g=0.80) on academic success. No significant differences were observed in the moderator variables related to publication type, institution, and experimental process durations; however, a significant difference was found regarding sample size. Based on the data obtained from the study, it is predicted that the effective implementation of the layered curriculum will enhance academic success.
