The Open Educational Resources Nursing Essentials (ONE) Project is a partnership between the Texas Higher Education Coordinating Board (THECB) and OpenStax, the world’s largest publisher of OER. This project was created to address the crisis-level nursing workforce shortage, driven largely by immense financial barriers to undergraduate nursing education. Through this project, the THECB and OpenStax worked alongside 94 authors and 152 reviewers to develop and publish 8 free, high-quality, open, and accessible nursing textbooks. These books align with AACN standards and competencies and offer NCLEX preparation support. During this session, we will discuss the collaborative end-to-end approaches and practices employed to achieve project outcomes. We will discuss how this collaboration began, the project’s goals and phases, the nursing textbook development process, and the quantitative outcomes achieved. We will also describe the needs analysis, user engagement, learning design, and review processes that drove the project.
