All teachers have at least a CDA (Child Developmen Associate) Credential, an AA (Associate in Arts) Degree or higher in Early Child Development, or an advanced degree in a related field such as Education, Music, Nursing, etc.  Grace Christian Nursery School sponsors ongoing teacher education and development. If one of the regular classroom teachers is unable to attend school , substitute teachers are provided. The substitute will be either a teacher from another class or someone we use on a regular basis to provide familiarity for the children.
