This study aims to determine the level of SPS offers in textbooks used in secondary schools in West Sumatra. This research is a descriptive study using a qualitative approach with a population of all physics textbooks for Class XII semester 2 published in Indonesia and used in secondary schools in West Sumatra. The sample of this study were four Physics textbooks that were most widely used in secondary schools in West Sumatra and three of them were recommended by the Ministry of Education and Culture. The instrument used was validated by 3 experts. the first expert got a value of 0.98% categorized as very valid, the second expert obtained a value of 0.96 categorized very valid and the third expert got a value of 0.85 categorized as very valid.
