The Virginia Theological Seminary offers Episcopal Children’s Curriculum as a FREE download. Three age groups are available: Preschool/Kindergarten, Primary grades 1-3, and Intermediate grades 4-6. All the materials you need are available, including step-by-step lesson plans that make it possible for individuals with limited or no previous experience leading a Sunday School program to have success.
Also available is Episcopal Curriculum for Youth. This curriculum is provided for “Younger Youth” (early teens/Middle School) and “Older Youth” (High School). All the materials are there for you including Leaders Guides with complete instructions for how to lead the classes.
As with any curriculum or packaged instructional plan, you may have to do some of your own adaptation of the materials to fit your context–one size does not fit all. But these materials provide enough guidance to enable you to be creative with your local adaptations.
