A report is presented of an evaluation study that was set up to monitor the effects of a bilingual program on students' progress in all subject areas, its effects on student attitudes towards the French language and culture, and the patterns of language usage in the bilingual classroom. The sample for the study consisted of three groups: a treatment group of two sixth grade bilingual classes, and two comparison groups comprised of sixth grade classes and a ninth grade class from a regular program. Standard tests and observation procedures were used to collect data. Analysis of the data indicated the following: (1) the treatment group performed as well as the comparison grade six class in subjects other than French, and better than both comparison groups in French; (2) the treatment group maintained more positive attitudes toward the French language and culture than the sixth grade comparison group; and (3) by the end of the year, the greatest percentage of French language used in the bilingual classroom was related to course content.
