This research has been carried out with the aim of determining the effectiveness of a Philosophy Education Program on the development of moral judgment, pro-social behavior and anger control among students. This experimental field study was a pre-test and post-test type with control group and conducting follow up stages. The statistical population of the study consisted of all second year High School female students in Ahwaz City: 40 students were selected out of 160 students by using a multistage cluster random sampling method and were assigned in an experimental group (20 people) and a control group (20 people) through simple random sampling. The experimental group was exposed to the Philosophy Education Program for 2 months and the control group didn’t receive any kind of intervention. The follow up stage was conducted after the post-test program and one and a half months after the intervention.
