Curriculum criteria are guidelines used to make decisions about curriculum and evaluate learning achievement. They include clearly stating curriculum goals and using them to choose content, materials, and activities. The criteria also involve engaging students in planning goals and assessing whether goals relate to society, community, individual learners, and are used to select learning materials and evaluate achievement. Characteristics of a good curriculum are that it evolves over time, is based on community needs, involves democratic input, results from long-term efforts, includes detailed plans, sequences subjects logically, complements other community programs, has educational quality, and allows flexible administration.
