This report, written in French and German, provides an evaluation of a pilot program, begun during the 1999-2000 school year, in which Kindergarten students (aged 5 to 6 years) in the French-speaking town of Cressier and the German-speaking town of Jeuss-Lurtigen-Salvenach, both in the bilingual Fribourg/Freiburg Canton of Switzerland,received 10% of their education in the partner (Frebch or German) language. The program was evaluated through classroom observation, a questionnaire administered to the parents, and interviews with the teachers. The results, which are largely positive, are discussed and potential problems and areas of concern are addressed. (AS)
