Independent school (Preschool  – Grade 8) seeks candidates to work closely with the Auxiliary Programs Director to ensure the smooth planning, coordination, and implementation of the afterschool and vacation programs, as well as provide teaching coverage during the school day when a teacher is absent. 

Respecting and embracing differences has been at the core of a Lesley Ellis education since the school’s early days. Our anti-bias curriculum is rooted in a developmental model of learning that engages children’s innate desire to observe, question, consider, and eventually think deeply about complex interpersonal and societal issues. In 2005, we received the Leading Edge Award for Equity and Justice from the National Association of Independent Schools, and we continue to learn and work against systems of injustice, including racism, by practicing behavior that demonstrates appreciation for multiple perspectives and engaging in conversations and actions that confront bias at all developmental levels.
