School Notes
- MISSION
- American Academy will achieve academic excellence through a challenging, sequenced curriculum emphasizing science, technology, engineering and math to provide our students with the tools to become the leaders of tomorrow. Together, students, faculty, parents, and community will cultivate character, civic responsibility, and intellectual development.
- ACADEMIC EXCELLENCE
- Students' thirst for knowledge are satisfied every day in every grade as they learn a body of knowledge that we all share, without gaps and repetitions. They learn reading and critical thinking by having something exciting to read and think about. And most importantly, students are taught and encouraged to take responsibility for their work and to self-advocate for the help and information they need as they are challenged and grow.
- A STEM EMPHASIS
- Science is a daily subject in most grades and STEM Discovery takes place throughout the year so that students are exposed regularly to exciting new worlds and innovations like biotechnology, space, engineering, nanotechnology, and many more. Parents will have a portal into their child’s education from a home computer or smartphone. Technology will be available throughout the school every day to enable excellence in education and streamlined communication for staff, students and parents.
- CONSISTENT CHARACTER DEVELOPMENT
- Character values are woven into the curriculum throughout the school day so that students learn the meaning of integrity, respect, and responsibility, and are regularly recognized for demonstrating these traits in their daily activities and interactions.
- A SCHOOL CULTURE OF RESPECT AND RESPONSIBILITY
- Staff, parents, and administration set an example of respect and responsibility for the students to follow each day. Students are taught how to interact kindly and respectfully with their peers and adults. Board, administration, staff, students and parents work together towards the common goal of academic excellence.
- A CHALLENGE FOR EVERY STUDENT
- Students are challenged at every level of ability, and taught to always raise the bar for themselves. High expectations are the norm and boredom is not an option.

School Reviews

We couldn't be happier with American Academy. The education is top notch, our kids love it, and we haven't had a teacher with disagreed with in 6 years/3 kids. Being a charter, 40 hrs of parent involvement is well worth the advantage over our local elementary.

We love this school! I have two kids who have attended American Academy since the beginning and both have been extremely well-prepared for high school. I can't compare this school to any other, since we never attended any other, but we did not have more than an hour or two of homework each night except on very rare occasions and though the expectations were high, I mostly felt that showed in the strict late policies and the expectation that students in 5th grade and above learn to advocate for themselves when they needed help in a subject. Both kids learned how to approach teachers respectfully and communicate in person and in writing to accomplish this self-advocacy, and my high school sophomore constantly refers to AA as the place where she learned this most important of life skills. The school doesn't work for everyone - if your student needs to be a straight-A student above all else, this may be too much for you. A's are earned, not handed out. But if you can allow your student to grow and learn without hovering and worrying too much, this school will open doors! I highly recommend American Academy!

We love the accountability, high academic standards, and ability grouping. This school is able to accommodate those kids that are off the charts academically, and public schools here do NOT do that.
