A program in English as a second language for students in New York nonpublic schools is evaluated. The program provided intensive English language supplemental instruction to enhance listening, speaking, reading, writing, cognitive, and conceptual skills in limited-English-speaking students in kindergarten through grade 8. Evaluation was accomplished through language and basic skills testing. The results suggest that the program was generally highly successful as measured by test score gains. All of the gains were above the program's criteria of success. Recommendations call for improved techniques for measuring student progress and increased student access to read-along tapes. The report contains background information, a description of the program and its organization, presentation of student outcome data, and conclusions and recommendations. (MSE)
