Many students want to continue their education to Senior High School (SMA) and Vocational High School (SMK), especially in the Pinggir District area. However, students and parents find it difficult to choose the best school due to the lack of information obtained. From this problem, a decision support system is needed to provide recommendations for determining the best SMA and SMK. The method used is ARAS (Additive Ratio Assessment). This method uses the concept of calculation in the form of ordering utility values (i) from the highest to the lowest value. The school data used are 8, namely SMAN 1, SMAN 2, SMAN 3, SMAN 4, SMAN 5, SMAN 6, SMKN 1, SMKN 2 and the criteria data are 7, namely School Facilities, Accreditation, Graduate Quality, HR, Extracurricular, School Achievement and Location. From the results of the research conducted, there are 5 schools with the best school recommendations and their calculated values, namely SMKN 1 = 0, 122477, SMKN 2 = 0.121488, SMAN 5 = 0.116763, SMAN 6 = 0.112653 and SMAN 1 = 0.108850.
