Academic Curriculum
Instruction at Princeton Academy is designed to be developmentally appropriate yet progressively challenging, ensuring that each grade builds upon the knowledge of the previous one.
Lower School (JK-Grade 4)
The Lower School focuses on foundational skills through specialized programs. In Language Arts, the school utilizes the Junior Great Books program for comprehension, alongside Word Journeys and Words Their Way for phonics and spelling. To support fine motor development, the school employs Handwriting Without Tears.
Mathematics is taught via the Everyday Math program, which balances concepts and problem-solving across six strands, including algebra and geometry. Science is inquiry-based, utilizing FOSS (Full Option Science System) to teach observation and data analysis. Additionally, students begin learning Spanish in Kindergarten, progressing to conversational and written proficiency by third grade.
Middle School (Grade 5-Grade 8)
The Middle School curriculum centers on five core subjects: English, Mathematics, Science, Social Studies, and Spanish. The English program emphasizes diverse literary genres and strengthens writing through the Junior Great Books program. Mathematics follows the University of Chicago Mathematics Project, focusing on real-life applications.
The Science program is highlighted by the Independent Science Project (ISP), encouraging analytical and creative problem-solving. In Social Studies, students develop research and critical thinking skills to analyze the past and its relevance to the present. The Spanish program integrates listening, reading, speaking, and writing; notably, 8th graders participate in an international exchange with the Colegio Sagrado Corazon de Sarria in Barcelona.
Athletics and Service Learning
The athletic program for grades 5–8 encourages students to balance academics with physical activity and leadership. Every student, regardless of skill level, is encouraged to participate in the following seasonal sports:
- Fall: Cross Country, Soccer, Golf.

Beyond the classroom and field, the Academy embraces Service Learning—a strategy that integrates community service with instruction and reflection. From JK through Grade 8, students engage in civic responsibility through projects often designed and implemented by the boys themselves.

Campus and Sustainability
The 50-acre campus features the Kalkus House (formerly the Manor House), named in honor of founding headmaster Olen Kalkus. Other notable facilities include the Athletic and Convocation Center (dedicated in 2006) and the William E. Simon Chapel Library (dedicated in 2008), which houses a silk painting of the Mater inspired by a Roman fresco.
Princeton Academy is a leader in environmental stewardship. Between 2012 and 2014, the school underwent a major renovation to implement green technologies, including:
- Geothermal Energy: 40 geothermal wells were drilled to reduce the carbon footprint of the HVAC system.
- Sustainable Design: The use of closed-cell spray insulation, LED lighting with occupancy sensors, and high-efficiency insulated glass.
- Natural Integration: A south-facing greenhouse that requires no man-made heating and a "dark sky" lighting philosophy to protect local habitats and stargazing.
Energy usage and savings from these initiatives are displayed on a public dashboard, allowing the school community to track their environmental impact in real-time.
