what makes us stand out.
At Guidepost, we join with parents on their mission to help their child grow and live well. Together, we design an education to empower each child to build the knowledge, skills, and confidence she needs to craft an independent, flourishing life.
Though there are many differences between the conventional approach and Guidepost, read more
about the Guidepost Montessori approach.
Montessori education is known world-wide for having positive impacts on both academics and social and emotional skills.
At Guidepost Montessori, when we design an environment to meet the developmental needs and interests of children alongside personalized care and support, the child can learn advanced skills at an accelerated pace.
Our students, for example, regularly learn to read by the time they’re 4-years-old and can perform all four math operations with 4-digit numbers by the end of their Kindergarten year.
The language and math skills of our kindergartners are on a par with what children in conventional programs learn in 3rd grade or beyond! What’s more, our students learn advanced academics joyfully—while simultaneously developing deep focus, self-discipline, and positive social skills.

Yes! The third year of our Children’s House program, designed for 3- to 6-year-olds, is the capstone kindergarten year. In this year, the child has been well-prepared to experience an explosion of literacy, learn advanced math concepts, and use her hard-won ability to focus, problem-solve, and persist through challenges to then make advanced gains across the curriculum. Children who continue with Guidepost through Kindergarten are often well-ahead of their peers when they enter 1st grade.
