This is from my Archdiocese web site:
Certification
A catechist is certified upon earning sixteen (16) credits (8 required, 8 elective) approved by the Office for Catechetical Formation (OCF). Required Credits (8) are earned through successful completion of each of the following core courses offered by the Catechetical Institute:
Overview of the Old Testament
Overview of the New Testament
The Person of Jesus
Foundations of the Church
Sacraments of Initiation
Sacraments of Healing and Vocation
Christian Anthropology
Catholic Moral Teaching
Elective Credits (8) are earned through the successful completion of the requirements associated with a variety of programs, seminars and workshops that are offered through the OCF. Upon review by the OCF, credits in theology that have been earned at a Catholic university or college can be applied toward the fulfillment of requirements for certification. Records of completed courses and earned credits should be verified and
kept on file in the local school/religious education office. Updated information is sent by the principal/DRE to the OCF in June.
Revised 2006
After 16 credits have been earned, college transcripts, copies of course cards, the completed application and principal’s/DRE’s verification form should be forwarded to the OCF. A formal certificate is awarded in recognition of the completion of all requirements.
Catholic School Teachers
All Catholic school teachers must complete the *Practical Applications *Course during their first year of teaching. This requirement fulfills one (1) elective credit. All Catholic school teachers must earn at least one (1) credit each year and complete certification within the first eight (8) years of teaching. Compliance with the certification policy is required in order to teach in a Catholic School within the Archdiocese.
Parish Catechists
Parish catechists must complete Basic Catechist Courses (I, II) within the first two (2) years of teaching. This requirement fulfills two (2) elective credits.
Professional Update
To maintain certification, Catechists must earn one (1) credit each year. Verification of this should be kept on file in the local school or parish office. Updated information is sent by the principal/DRE to the OCF in June.
I know people who teach CCD, and honestly, they do not have certification. Perhaps the DRE does, but they do not.
There was nothing on the site about maintaining a catholic lifestyle, perhaps that is understood, but I agree you teach with more than words.
