Cultural influences and urban ecological factors are significant mediators in the emotional, sociobehavioral, and academic development of low-income urban Hispanic students. A review of the literature indicates that the school psychology profession has an underdeveloped knowledge base explicating how ethnocultural variables and socialization practices impinge upon the developmental and learning experiences of the Hispanic student. Psychocultural variables and the socioadaptational patterns of Puerto Rican families and students are delineated and elucidated. An organizing assessment and intervention framework as well as an illustrative case with specific approaches are described. Recommendations for psychoeducational policy, training, and practice are also provided. School psychology directors, practitioners, and trainers are urged to reexamine and reconceptualize service delivery strategies to be more culturally and phenomenologically compatible with the needs, differences, and strengths of this specific population.
