Early Childhood
Curiosity, Connection, and Confidence Begin Here

The Early Childhood Program at Lesley Ellis School offers play-based preschool, prekindergarten, and transitional kindergarten in Arlington, MA.
Designed for young learners, the program helps students build curiosity, confidence, independence, empathy, and foundational academic skills.
Children learn through meaningful play, hands-on exploration, storytelling, movement, art, outdoor discovery, and conversation. Teachers listen carefully to students’ ideas and questions, then design learning experiences that support social-emotional growth, early literacy, early numeracy, problem-solving, collaboration, and creative expression.
Small class sizes allow teachers to know each student well and provide personalized support. As part of an inclusive preschool through grade 8 independent school, young learners also benefit from a caring community, specialist teachers, assemblies, outdoor learning, and a smooth transition into kindergarten and elementary school.
Lesley Ellis serves preschool, prekindergarten, and transitional kindergarten students who are ready to explore, play, build friendships, develop independence, and begin seeing themselves as capable learners.

Ready for Kindergarten and Beyond
By the end of our early childhood program, our growing children are well prepared to move into kindergarten. They have the skills, confidence, and curiosity to thrive. They know how to ask questions, express ideas, collaborate, and persevere.
Our Early Childhood Assemblies also play a meaningful role in this growth. These gatherings give children the chance to speak and perform in front of larger audiences, building confidence and a sense of belonging in the broader division. They see what other classes are learning, recognize shared themes in specials, and occasionally join mini-lessons led by specialist teachers. It’s often the quietest children who surprise us most, volunteering to step up and share their voices with pride.
Most of all, children leave our early childhood program seeing themselves as capable learners and valued members of a caring community.
A Multilingual and Inclusive Community
Our classrooms reflect the diversity of our families and the broader world. Children bring their full selves, and languages, into the classroom. Teachers support expressive and receptive communication for all learners, including those from multilingual homes.
Through language play, shared books, and conversations, children gain the tools to understand and be understood. We celebrate the many cultures, identities, and family structures that make our community vibrant.

Outdoor Exploration and Learning
Early childhood students at Lesley Ellis explore new territory in a thoughtfully designed outdoor classroom, where getting dirty is not only ok, it’s part of learning. We know that developmental skills are acquired in all different environments, and we have constructed this space for kids to be immersed in a wholly hands-on world, where learning takes place in unimagined ways. Whether making dinner in the mud kitchen, turning over logs to see who’s hiding, creating music with found objects, or experiencing how water falls down a wall, we aim to provide a canvas for imaginative self-expression in this wonderfully creative, unstructured environment.
Observation, Assessment, and Growth
Assessment in early childhood looks different at Lesley Ellis. Teachers are expert observers, documenting progress through portfolios, photos, and narrative notes that celebrate each child’s development.
Families also receive daily snapshots of classroom life through “Today We,” a brief digital journal that shares highlights from the day. In words and pictures, it often features which specials the children participated in, special guests who visited, and key learning moments. Parents appreciate this window into the classroom, as it offers rich talking points for the car journey home (especially when “What did you do today?” gets answered with “Nothing!”).
To strengthen our ongoing observation and deepen our understanding of each child, we also use the Ages & Stages Questionnaire (ASQ), a developmental screening tool widely used by pediatric practices, early intervention programs, and Head Start agencies. The ASQ is completed by parents and helps assess growth in communication, gross motor, fine motor, problem-solving, and personal-social skills.
At Lesley Ellis, we use the ASQ to gain insight into children’s development from both the teacher and family perspectives. It also helps us look at trends across our classrooms. For example, one year’s results showed that while most of our children were developing typically, their strongest area was problem solving and their lowest was fine motor ability. In response, teachers increased fine motor opportunities in class and shared ideas with parents for home. The tool also provides a common language for home and school, helping families and educators talk concretely about developmental milestones and next steps.
