This research aims to examine the implementation of these regulations by conducting a case study at Labuhan Batu State Elementary School. The research method used is descriptive-qualitative, with data collection techniques through observation, interviews, and documentation. The research results show that the implementation of the Ministerial Regulation at the Labuhan Batu State Elementary School has had a positive impact on the national assessment process. Teachers have been able to understand the national assessment guidelines better and integrate them into the school curriculum. Apart from that, the implementation of this regulation also increases awareness of the importance of assessment in improving the quality of learning and evaluation. However, challenges such as the availability of resources and a deep understanding of assessment concepts are still obstacles.
