Authorized by the Commission on Teacher Credentialing, the Early Childhood Special Education Added Authorization (ECSE_AA) may be appended to a preliminary or Clear Education Specialist (Mild-Moderate or Moderate-Severe Specialization) Credential. The ECSE_AA prepares teachers to deliver high quality school or in-home services to young children with disabilities (birth-5) and to their families. The added authorization is designed to meet California requirements for teaching special education in early childhood settings.
