In a learning process, the component that determines the success of a process is evaluation. Through evaluation, the community can find out the extent to which the delivery of learning or educational goals or a program can be achieved in accordance with the desired goals. Evaluation is the process of describing, obtaining, and providing useful information for assessing decision alternatives. Evaluation uses information on measurement and assessment results. The CIPP evaluation model is an evaluation model developed by Stufflebeam which aims to help improve the curriculum, but also to decide whether the program should be discontinued. Through this CIPP evaluation, it can be seen the development of learning outcomes, intelligence, special talents, interests, social relations, attitudes and personality of students or students as well as the success of a program. Christian religious education is an effort to prepare people to believe, understand, and practice Christianity itself. Christian Religious Education, especially in Sunday Schools, also applies a curriculum. The curriculum which is always closely related to evaluation aims to see the effectiveness of the learning received and also input for improvement. The Sunday School, especially GPIA Kasih Heavenly Jember, also applies what is called online learning, learning that is carried out by teachers and children using laptops or computers connected to the internet. In this study, the authors conducted a qualitative descriptive research approach through observation, interviews and documentation naturally. Therefore, the evaluation at the GPIA Kasih Heavenly Jember Sunday School is based on the results that have been described in the curriculum, namely something that is planned as a guide to achieving educational goals and has a very important role function because it does not only involve planning but how strategies and learning methods, media and learning resources as well as the process of implementing plans that involve two subjects, namely educators as implementers and students who will apply the curriculum concretely in their lives.
