The research project, “What works? A study of effective ECMHC programs,” (Duran et al, 2009), affirmed that one of the five essential core areas of knowledge for effective consultation is cultural and linguistic competence, related to working with consultees (staff, families, children) and ECE organizations. Some study participants found it difficult to articulate how they understood, approached, and successfully engaged young children and their families in ways that addressed or responded to ethnic, cultural and linguistic diversity. Highly qualified consultants must be able to recognize, describe, and integrate the influence of culture and language in the consultative process; demonstrating cultural competence through knowledge, skills, and specific practices that are responsive to diversity.
