The extent to which primary school students participating in an English-Ukrainian bilingual program in Manitoba, Canada, were acquiring skills in Ukrainian and English language arts was evaluated for the 1981-1982 school year. This program, which was instituted in 1979, provides half of the instruction in English and half in Ukrainian. Using "Ukrainian Language Tests," scores were collected on first-grade students and third-grade students. The "Metropolitan Achievement Test-Primer Level" (MAT) was administered to first-grade students in the bilingual and regular programs, and the "Canadian Tests of Basic Skills--Level 9" (CTBS) was administered to third-grade bilingual students and control-group students. After about 2.5 years in the program, students were performing at about the 75 percent level on Ukrainian oral skills, and were developing reading and writing skills. After 4 months in the program, students' English language skills were not as advanced as those of control-group students, but by grade 3, these differences disappeared. It is concluded that students in the English-Ukrainian bilingual program are developing English language arts skills at a level comparable to that displayed by students in the regular program, as well as learning the Ukrainian language.
