Drawing on qualitative data collected in a sample of colleges as part of a larger study on the implementation and impact of Assembly Bill 705 in California, this paper explores the rollout of corequisite reforms, focusing on the use of embedded tutors in introductory math and English courses as a strategy to meet to the needs of students. This paper highlights promising practices identified through extant research and fieldwork at study institutions, provides additional evidence on the value of the reform, discusses challenges, and makes recommendations for the field.
