In order to study the evaluation of higher education in Sri Lanka，on the basis of a brief introduction of Sri Lanka’s higher education，with the help of literature research method，a systematic review had been conducted on Sri Lanka’s basic approach to the evaluation of higher education in national universities since 2017. The study showed that the higher education assessment of Sri Lankan national universities was conducted under the leadership of the Ministry of Higher Education and University Grants Committee，which developed evaluation criteria such as the Quality Assurance Handbook for Sri Lankan universities，the Higher Education Quality Assurance Committee should be responsible for the implementation. The concepts of student-centred learning and results-based education were put into the higher education research and evaluation programme by using both external and internal evaluation. The external evaluation was an act of the state. The Quality Assurance Commission for Higher Education was responsible for the institutional review and subject evaluation of national universities during external evaluation. The external evaluation had the unity of evaluation standards and the authority of evaluation results. The internal evaluation was the internal behavior of the national university，which was organized by the university itself and laid the foundation for the external evaluation. The evaluation of higher education in Sri Lanka followed the relevant laws and regulations and had its own characteristics. The quality assurance system had its advantages and limitations，and it also faced many new challenges. Based on the research results，this paper put forward some main suggestions，which had reference significance for promoting the modernization of higher education evaluation in our country.
