The mission of the ESTS Project is to change the culture of how emergency substitute educators and the greater substitute community are supported, trained, and valued within public education. This course is a monthly series to support emergency substitute educators and certificated substitute educators in developing and refining their instructional and professional practices. Each month, the SubCollaborative will focus on a specific topic (e.g. classroom management, student engagement, high leverage instructional practices, classroom technology) aligned with ESTS Project professional development offerings to dig deeper into the selected topic and allow attendees to discuss the topic in practice with their peers in breakout groups (regional, grade level, subject matter).
