Requirements
- Annual training
- Each staff person working directly with children more than 20 hours per week, including the director, must obtain at least 24 hours of training each year, covering all 7 competency areas within 2 years; staff working 20 hours or fewer complete half. First aid/CPR training must include a hands-on component.
- Lead teacher
- Educators counted in ratios must be at least 18, hold background-check clearance, and complete the ECECD-required health and safety trainings within 3 months of hire plus an approved child development course (or 3-credit early care and education course) within 12 months. No degree is required at entry level.
- Director
- Directors must be at least 21 and either hold a qualifying early childhood program administration credential or coursework (e.g., Program Management 1, the NM Child Development Certificate, a CDA, or an associate degree in ECE) plus 2 years of experience in an early childhood setting, or a bachelor's degree or higher in ECE or a related field plus 1 year of experience.
- Worth knowing
- Infant/toddler group-size caps were tightened in the 2022 rules; providers that exceeded them before promulgation are grandfathered as long as ratios are maintained. 5-year-olds and 6+ are both 1:15 with max group 30; combined-age groups have their own table.
A ratio is easy to read and hard to hold at 3pm on the playground.
