Globally, higher learning institutions face challenges in successfully implementing curricula to enhance student learning. This study investigated factors for effective curriculum implementation in higher learning institutions in Tanzania, particularly (i) to examine the extent to which factors (characteristics of lecturers and institutions, the curriculum itself and governmental support) contribute to effective curriculum implementation and (ii) to assess the relationships among the factors contributing to effective curriculum implementation. This study employed a quantitative research approach and a descriptive research design. A total of 251 students from four fields of study at the Institute of Accountancy, Arusha, were selected via simple random and stratified sampling techniques. Statistical Packages for Social Sciences version 26.0 was used to compute the mean, standard deviation, independent samples t test, one-way analysis of variance (ANOVA) and correlation from the data collected through the questionnaire. Guided by ecological systems theory, the findings revealed that the majority of students (80.5%) perceived that lecturer and institutional characteristics, the nature of the curriculum, and governmental support contributed to effective curriculum implementation. Furthermore, there were positive relationships among the study factors, with the highest correlation between the nature of the curriculum and institutional characteristics. On the basis of these findings, the study recommends considering factors related to lecturer and institutional characteristics, the nature of the curriculum, and governmental support to effectively implement curricula and improve student learning in higher learning institutions.
