The Utah State Dual Language Immersion Elementary Model follows a 50:50 model design where the instructional day in grades K-5 is divided between two high-quality classrooms, each for a fifty percent of the instructional time. In this fifty-fifty model, students spend half of their school day in the immersion language and the other half-day in English. All state-sponsored programs are required to use two teachers, one who instructs exclusively in the immersion language for half the day and the second teacher who teaches exclusively in English the other half of the day.
