I understand writing your own curriculum.  I did it for years.  I enjoyed the process and it allowed me to emphasize the important parts of discipleship that the Scriptures teach and I wanted my students to grasp.

However, I also love the curriculum put out by LifeWay, which is part of the publishing arm of the Southern Baptist Convention.  The curriculum published for persons who are developmentally disabled is called ACCESS.  It is excellent and comes with a teacher’s guide and teaching helps.  You can review the curriculum, teacher’s guide for a minimal cost.  The Teacher’s Packet with teaching helps is expensive but well worth the cost.  However, you may not want to spring for the almost $20 until you view the Pupil’s books and teacher’s books.
