    Why St. Peter's

    More than a school — a way of growing up.

    "To bring out the best in every child, using Montessori curriculum, guided by the traditional Anglican appreciation of diversity, inclusion, and open inquiry."

    More than just academics

    We nurture curiosity, independence, compassion, collaboration, critical thinking, and spirit — the whole child.

    A sanctuary campus

    Four Montessori programs — from Infant & Early Toddler to Elementary — share one peaceful, green campus, so your child can grow from first steps to sixth grade in a place that always feels like home.

    We are a community

    A 60-year West Valley family — parents and guides working together for the benefit of every child.

    Our Programs

    One continuous Montessori journey

    From first steps to innovative thinking. We offer a prepared path through the planes of development — 3 months to 6th grade, all on one peaceful campus.

    3–18 months

    Nido I

    A gentle "nest" for infants — sensory-rich, family-centered first discoveries.

    18–36 months

    Nido II

    Walking toddlers build language, coordination, and joyful independence.

    3–6 years

    Children's House

    Our AMI-recognized primary — where practical life meets academics.

    1st–6th grade

    Elementary

    Big questions and cosmic education — abstract thinking takes root.

    The St. Peter's Difference

    What sets our classrooms apart

    Authentic Montessori, delivered by trained guides in an environment built for real childhood.

    AMI Recognition

    A traditional approach to Montessori, guided by the Association Montessori Internationale (AMI). Our Children's House is AMI-Recognized — the mark of authentic Montessori.

    A Diverse Campus

    Our community brings the world together — students and staff represent 9 countries of origin. That everyday diversity gives children a broader view of the world and helps them develop a sense of belonging.

    Traditions We Share

    We celebrate together all year with traditions like the Christmas Parade, International Festival, Fall Festival, and Movie Night.

    Master Gardener Program

    Elementary students learn earth science, math, and stewardship in their home-grown garden. The classroom extends beyond four walls: every classroom has its own dedicated outdoor environment.

    Elementary Reading Specialist

    Dedicated weekly reading support helps every elementary school child find their footing as a confident reader.

    Uninterrupted 3‑Hour Work Cycle

    Protected morning time lets deep concentration and real independence take hold.

    Low Ratios

    Small groups mean guides truly know each child and can follow where their learning leads. We have 1:3 teacher to child ratios in our infant rooms and 1:5 for toddlers.

    Screen-Free Classrooms

    No screens in our classrooms — children stay present in mind and body, and aware of the world around them. We nurture the spirit through character, grace, and courtesy.

    One Peaceful Campus

    All four of our programs — from infant through elementary — share a single sanctuary campus, so children grow from their first steps through sixth grade in one calm, welcoming place they know as home.

    Montessori, simply put

    Follow the child, and learning follows.

    In a Montessori classroom, children choose purposeful work from beautifully prepared shelves and learn by doing — touching, building, and discovering. Mixed-age communities let younger children learn from older ones, and older children lead. The result isn't just knowledge; it's a lifelong love of learning.

    Arizona's first Montessori Purple Star School

    Just minutes from Luke Air Force Base, St. Peter's was the first Montessori school in Arizona named a Purple Star School for its commitment to military-connected children. Because our curriculum truly follows the child, families who move can pick up right where they left off — and every family, from Luke and from allied units around the world, is welcomed as our own.

    Loved by the parents who know us best

    "

    When choosing a school for our daughter, we considered schools that would foster the idea that she can do anything. It was not long before we realized that the loving environment at St. Peter's Montessori would nurture her needs specifically, with joy and marvel.

    The teachers do a great job of maintaining a peaceful environment where children can thrive academically and socially.
