The research literature on student retention is voluminous and longstanding. However, a unified theory of retention remains elusive; instead a variety of explanations and approaches have been developed. This article uses two discourses, "integration" and "adaptation," to make sense of the findings from a survey of teachers who taught students enrolled for the first time in seven tertiary institutions in New Zealand. While the article reports results from the survey, it focuses particularly on how tertiary teachers understand diversity; whether and how they accommodate diversity in their teaching. It offers some critical reflections on these teachers' views about diversity. [This project was funded by the Teaching and Learning Research Institute.]
