Abstract	Background: Following the promulgation of the Education and Training Policy (ETP 2014), the Ministry of Education, Science and Technology (MoEST) through the Tanzania Institute of Education (TIE) overhauled early primary education, prioritizing foundational literacy and numeracy under the 3Rs curriculum framework (Reading, Writing, and Arithmetic / KKK: Kuroma, Kuandika, na Kuhesabu) for Standard I and II. While this policy aimed to eliminate foundational learning deficits, empirical synthesis regarding its longitudinal pedagogical efficacy, classroom execution, and structural constraints remains critical for ongoing curriculum refinement. Objective: This scoping review systematically maps and evaluates peer-reviewed empirical literature, curriculum policy documents, and national assessment reports regarding the pedagogical efficacy, instructional implementation dynamics, and operational challenges of the 2014 revised 3Rs curriculum framework in Tanzanian primary schools. Methods: Guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) guidelines and Arksey and O'Malley's methodological framework, systematic searches were executed across electronic databases including ERIC, Scopus, Web of Science, PubMed, Google Scholar, and African Journals Online (AJOL) for studies published between 2014 and 2026. Results: From 380 identified records, 22 core empirical studies met all inclusion criteria. Synthesized findings demonstrate that while the 3Rs framework significantly improved structured phonetic awareness and basic counting competencies in urban and well-resourced schools, systemic implementation barriers persist in rural public primary schools. These barriers include large class sizes (70-100+ pupils), severe textbook-to-pupil ratio imbalances, inadequate continuous teacher professional development in early grade reading methodologies (EGRA/EGMA), and diagnostic assessment gaps. Conclusion & Recommendations: The 3Rs curriculum reform established a vital structural foundation for early grade learning in Tanzania. To maximize pedagogical efficacy, strategic recommendations include institutionalizing continuous school-based teacher mentoring programs by TIE, procuring multi-sensory early grade learning kits, expanding remedial literacy/numeracy support, and reducing pupil-teacher ratios.
