Working in a research collaborative between Denver Public Schools and the University of Colorado Denver, the authors selected Bruce Randolph High School (BRHS) as a case study because of its growth on state academic achievement tests and because of its multilingual learners. After a difficult beginning, BRHS has established an inclusive culture of expectation for learning and community participation, a reciprocal instructional culture emphasizing instructional coaching and continuous improvement, a strong emphasis on language development and literacy across the curriculum, and interventions to prevent course failure. These characteristics, facilitated by the school's Innovation Status in the district, are central to its emerging success.
