The Early Learning and Care Trainer Reflection Tool outlines evidence-based practices grounded in research on equitable approaches to adult learning, professional ethics, and trainer competencies. It complements and expands on information in California Early Childhood Educator Competencies—Supplemental Performance Area: Adult Learning and Coaching. The tool identifies key knowledge, skills, and behaviors of trainers within the following content areas: professionalism; culture, diversity, and equity; knowledge and expertise; instructional design; facilitation; and assessment and evaluation. For each content area, the tool offers a brief statement of importance, guidelines that describe related behaviors, and examples of the behaviors in practice. The tool is meant to support self-reflection and professional growth and enhance the work trainers are already doing.
