Therefore, the importance of conducting assessment design training in the 2013 Curriculum. This activity was carried out in three stages, namely preparation, implementation, and completion. The preparatory phase is carried out by coordinating with the State Junior High School in the South Coast, surveying the location of service delivery, determining the location of service, and technical preparation of training and instruments. The implementation phase is carried out with three methods, namely lecture and training, and exercises to design the assessment in the 2013 Curriculum, the last stage is analyzing the questionnaire and the work of the teacher to make a report.
