Materials produced under this project, undertaken for the Child Development Associate (CDA) Consortium, reflect two purposes: (1) to identify specific skills and behaviors needed by teachers working with preschool Mexican-American children and (2) to develop an assessment process to evaluate the identified competencies, skills, and behaviors. Observations of a Head Start Summer Program in Houston, Texas, were used to determine 54 competencies unique to a teacher of Spanish-speaking Mexican-American preschool children. These competencies are grouped into three skill categories: (1) enhancing children's verbal and interactional behaviors; (2) building a positive self concept; and (3) developing a liaison between the parent, the school, and the child. Two assessment instruments, developed to measure the competencies, are similar in content but different in format. Instrument 1 includes a rating scale, a provision for documentation of curricular activities, and space for comments concerning the classroom environment, teacher behavior, and the length of time required to assess the CDA candidate. Instrument 2 includes observational comments, documentation of curricular activities, and a rating scale. These instruments have not been field tested. (ED)
