Our curriculum

Planned with care, every day

We welcome you to one of the area's premier private schools. Our school offers Montessori education as the foundation, along with the Common Core State Standards and the STEAM program — an environment designed for children to joyfully explore, learn at their own pace and maximize their potential to be independent.

Daily, weekly and monthly lesson plans enrich each child's learning across language-based phonics, math concepts and cultural arts. We look forward to guiding your child with love, care and dedication within our safe and secure facility — Diamond Bar Montessori Academy is where every child succeeds!

Our teachers plan daily, weekly and monthly lessons covering language-based phonics, math and cultural arts. S.T.E.A.M. activities are woven in throughout, and we track each child's progress so every learner is supported and challenged.
