This study aims to analyze the problem solving abilities and reasoning abilities of 14-14-15 year old junior high school students through the completion of the 2015 PISA questions which are International standard questions which PISA 2015 had never been given before. This study used a qualitative research approach. Qualitative approaches were chosen with the aim of revealing more carefully the mistakes of students in completing the PISA 2015 problem. In addition, with a qualitative approach researchers can communicate directly with respondents to find out the mathematical abilities of students through the completion of the PISA 2015. Based on data analysis conducted on 120 people students by completing the 2015 PISA questions in the category of problem solving abilities of students, most of the students were unable to answer the question. The biggest obstacle experienced is students do not know the completion steps that must be done in solving the problems given. In the category of reasoning ability, where the problem is still inductive reasoning, students are able to answer well, but for deductive reasoning students are not able to provide possible answers.
