The Challenge Recruiting and retaining World Language teachers in the rural South is difficult. It is even more challenging for Latinx teachers of the Spanish language. How do Latinx Spanish teachers in the rural South perceive experiences that help or hinder retention? In what ways are Latinx Spanish teachers navigating their role as advocates for linguistic and cultural diversity in their rural schools and communities?

This chapter provides an overview of Clemson University's Teacher Learning Progression program, which offers participating middle school science, technology, engineering, and/or mathematics (STEM) teachers with personalized advanced credentials. In contrast to typical professional development (PD) approaches, this program identifies individualized pathways for PD based on teachers' unique interests and needs and offers PD options through the use of a “recommender system”—a system providing context-specific recommendations to guide teachers toward the identification of preferred PD pathways and content. In this chapter, the authors introduce the program and highlight (1) the data collection and instrumentation needed to make personalized PD recommendations, (2) the recommender system, and (3) the personalized advanced credential options. The authors also discuss lessons learned through initial stages of project implementation and consider future directions for the use of recommender systems to support teacher PD, considering both research and applied implications and settings.
