One of the teacher's abilities in supporting learning objectives is to design learning products according to the needs in the field. To determine the quality of the developed product, the teacher must conduct several tests involving experts, students, and teachers. This study aims to assess the quality of the learning model that has been developed by researchers, namely the Contextual Teaching & Learning (CTL) learning model to improve students’ life skills through Islamic Religious Education (IRE) subjects. This research is a development phase in research & development methods focusing on testing the validity, practicality, and effectiveness of the learning model. There were three groups of participants included in this study, namely experts, teachers, and students, who were selected using a purposive sampling technique. Data were collected using several instruments, namely: (1) validation sheets, (2) teacher response questionnaires, and (3) life skills observation sheets. The collected data is then analyzed quantitatively to determine the categories of validity, practicality, and effectiveness. The study results show that the CTL learning model is proven to be valid, practical, and effective in improving the life skills of high school students.
