The purpose of this practicum was to develop a model in-service program for training mainstream teachers of Spanish speaking pupils. As the Spanish speaking population of the Norwalk, Connecticut community has grown over the past decade, the school problem of dealing with the non-native English speaker was identified. Through the initial financial facilities of an Emergency School Aid Act (ESAA) grant, a model inservice training program for mainstream teachers of Spanish speaking pupils was developed, conducted, and evaluated. This model was developed specifically for secondary school mainstream teachers (grade six through twelve) who must cope daily with the Spanish speaking pupils. In addition, through a liaison between the secondary and elementary levels, the applicability of the model, with some modifications, was evident at the elementary level. The program, through the careful selection of administrative, guidance, and teaching personnel, provided a de facto insertion of the model into the seven secondary schools of the city. An assessment of the total practicum indicated that the in-service participants did become a cadre of teacher trainers within their own builders, thus effecting an instructional improvement within the total secondary school system.
