Requirements
- Annual training
- No fixed statewide clock-hour total in the rule: directors, teachers, and assistant teachers must complete the annual training required to stay current on the Montana ECP Practitioner Registry (ARM 37.95.162). Teachers at school-age-only facilities need at least 8 hours of continuing education annually; a health-and-safety review course is required at least every 3 years, and CPR/first aid certification within 30 days of hire (ARM 37.95.163).
- Lead teacher
- An early childhood lead teacher (ECLT) must be at least 18, current on the ECP Practitioner Registry, hold CPR/first aid certification, complete teacher orientation, and have either two years' experience in an early childhood program plus 32 hours of ECP training, or ECP Registry level 2 or higher (ARM 37.95.622).
- Director
- Directors must be at least 18, current on the ECP Registry, complete teacher orientation, and qualify via ECP Registry level 4+; level 3 plus 2 years' experience; level 2 plus 3 years; or a bachelor's degree plus 120 hours of approved training; plus a program management essentials course within 60 days (ARM 37.95.624).
- Worth knowing
- Montana's ratio bands are 0–23 months (1:4, group 12), 2–3 years (1:8, group 16), 4 years (1:10, group 24), 5+ (1:14, group 32); although 'toddler' is defined as 19–36 months, children 19–23 months count in the 0–23-month band. Mixed groups follow the youngest child. DPHHS rulebook version reviewed: rev. 12/21.
A ratio is easy to read and hard to hold at 3pm on the playground.
