Knowledge of curriculum design is important for understanding the arc of the educational year. If teachers have some experience of this they will better understand the importance of each unit they are teaching during the year and how it relates to other units both past and present. It is also good for them to understand the reasons behind the model for the curriculum they are teaching. Most employers will be impressed if a teacher has done some curriculum design in the past as this indicates the teacher has shown initiative and interest in the wider scope of their job. Administration is a large part of teaching and so any experience in this area is usually favourable.
