While mathematics pathways are not new, there is still a long way to go towards wide-scale adoption and normative practice. The premise of this monograph is that there is expertise to be shared and issues still to be addressed. The monograph comprises chapters organized along topics that are aligned with the DCMP theory of change. The DCMP believes that systemic and sustainable change is best achieved through a process that is faculty-driven, administrator-supported, policy-enabled, and culturally reinforced. We hope that each chapter will provide the guidance and inspiration for improving student success in mathematics education through the widespread adoption, implementation, and continuous improvement of mathematics pathways.
