This research aims to develop high quality PMR based on Student Worksheet (LKS) to facilitate mathematical reasoning ability of grade XI students of SMA Negeri 1 Lubuklinggau. This research used research and development method (Research and development) and the stage of Analysis Design, Development, Implementation, and Evaluation. In the development stage, there are two kinds of processes, namely the development of LKS and LKS validation, then evaluated LKS by the experts of linguists, and media experts. Validity of LKS was developed categorized “Valid” with an average score of 3.09 was determined based on the LKS assessment result by 3 experts (material experts, linguists, and media experts) maximum score was 4.00. Data analysis used LKS Practicality analysis developed “Praktis” with an average score of 3.38 is determined based on the result of student response to LKS. Descriptive and statistical analysis. The effectiveness can be seen from the results of students achievement tests. Based on the results of the Test Achievement shows that the percentage mastery learning class XI SMA Negeri 1 Lubuklinggau was 87%.
