San Tan Charter School began in 2006 as a small Montessori preschool and kindergarten in Gilbert, AZ. In response to parent concerns about limited and costly education options, it evolved into a tuition-free public charter school in 2008, approved by the Arizona Board for Charter Schools.
What started with fewer than 100 students has grown into a thriving PreK–12 community serving over 1,000 students. Built on an inquiry-based curriculum with Montessori influences, San Tan now includes award-winning educators and is proudly accredited by AdvancED, reflecting its commitment to educational excellence and continuous growth.
San Tan Charter School firmly believes in promoting character education in all areas of the school day. Whether at work, at home, or at play, there are basic values that define ethical behavior. These values are not political, religious, or culturally biased. Josephson Institute calls them the Six Pillars of Character, and they form the basis of all Institute programs at San Tan Charter School, these pillars are as follows:
This Pillar encompasses a variety of qualities: honesty, integrity, reliability, and loyalty. Being trustworthy means keeping promises and doing one’s best not to deceive, even with white lies or statements that one might defend as “technically true.”
The Golden Rule is the most useful guide here: Treat others as you wish to be treated. That means being courteous, listening to others, and accepting individual differences.
This Pillar includes accountability, self-control, and the pursuit of excellence. Being responsible also requires that we carefully consider the consequences of our choices before we make them.
Being fair means playing by the rules and not taking advantage of others. A fair person makes informed judgments without favoritism or prejudice and does not blame others carelessly.
Kindness, compassion, altruism — these are the heart of ethics. Of course, some ethical decisions inevitably cause pain, but the caring person acts to minimize hardship and to help others whenever possible.
Good citizens work to make their community better. They are committed to protecting our environment and to making our democratic institutions work. They know the law — and they often do more than it requires and less than it allows.
We’ve watched our daughter blossom in confidence, independence, and joy since joining the Montessori program. She genuinely loves learning again.
