A description of a bilingual education program at the elementary school level spanning five years since its inception is presented in this report. The home-school language switch from English to French made by control and experimental classes involved total immersion in the French-taught curriculum. While focusing on the educational objectives of the experiment, selection of classes, curriculum design, evaluation of student achievement, and student attitudes, this article emphasizes findings which encourage the continuance and development of programs of this nature.
