Recent years have witnessed a surge in evidence on preschoolers' emotional development as crucial for both concurrent and later well-being and mental health, and for learning and academic success. Given the importance of building such strengths, assessing emotional competence skills is important to aid early childhood educators in focusing programming for individuals and classrooms. Based on these assertions, this article is structured as follows: (1) outline important issues regarding developmentally appropriate early childhood assessment, particularly of emotional competence; (2) discuss use of culturally relevant standards of attainment of such skills in assessing student progress; (3) define the skills of emotional competence; (4) describe a model leading from developmentally appropriate emotional competence skills to assessment and programming; (5) suggest some possible tools for schools to use in assessing emotional competence of young children; (6) give guidance for new measurement development, and (7) suggest needed policy and practice in this area.
