With the Gifted and Talented Education (GATE) program, Honors courses, Advanced Placement classes, International Baccalaureate, and Project Lead the Way, students are given a wide range of opportunities to excel academically and prepare for college.  Elementary and Middle School Advanced Academics Gifted and Talented Education is provided for all identified students beginning in third grade. We are committed to identifying and nurturing the unique strengths of advanced learners. As part of this effort, all second-grade students are administered a cognitive reasoning assessment to help determine potential eligibility for the GATE program. Beyond this universal screening, students at any grade level may also be referred for GATE consideration by parents or teachers. The GATE program is offered at the elementary school level as an after-school enrichment and promotes complex levels of thinking by working collaboratively, seeking innovative solutions, and challenging their unique, creative abilities. At the middle school level, GATE students can participate in Honors classes, including History, Social Studies, English, and Advanced Math.  High School Advanced Academics At Charter Oak Unified School District, we empower motivated learners with two of the most rigorous, globally recognized college-level curricula: Advanced Placement (AP) and International Baccalaureate (IB). Both programs challenge students to think critically, conduct in-depth research, and communicate their understanding—skills essential for success in higher education and professional life. Program Highlights: Advanced Placement (AP) College Credit & Placement Students may earn college credit or advanced standing at thousands of universities nationwide by scoring well on AP exams. Flexible Enrollment Open to any motivated student; no prerequisite “AP track” needed. Teachers support newcomers and experienced scholars alike. International Baccalaureate (IB) Holistic Diploma Program (Grades 11–12) A two-year curriculum that emphasizes intercultural understanding, inquiry-based learning, and community engagement. Global Recognition The IB Diploma is widely respected by universities around the world for its rigor and emphasis on well-rounded development.   Why Choose AP or IB? Academic Rigor Both programs push students beyond standard high-school coursework, fostering maturity and resilience. College Readiness AP and IB graduates routinely outperform their peers on college assessments and persist to graduation at higher rates. Competitive Edge Admissions officers value the challenge of AP/IB on transcripts—signal your readiness for the demands of higher education.   How to Enroll in AP/IB Meet with Your Counselor: Discuss your interests, strengths, and academic goals to build a personalized plan.

Every person in our district plays a role in educating our scholars. We see it in the classroom, where teachers help students grow in knowledge, confidence, and purpose. We see it in the leadership of our principals, who guide their schools with care and vision. We see it in staff such as our counselors, psychologists, and social workers, who support students and families through learning challenges or difficult moments; our custodians, who create clean and welcoming campuses; and our food services team, who ensure students have access to healthy meals each day. These are just a few examples of the many ways our employees make a difference for students across every school, program, and department in Charter Oak Unified. Next week, we will celebrate Certificated Appreciation Week, an opportunity to honor the credentialed educators who inspire, challenge, and support our students each day. They teach, counsel, assess, and lead our students and schools.  The following week, we will celebrate Classified School Employee Week, which recognizes the support staff and frontline employees who keep our schools running. They serve meals, maintain campuses, support classrooms, assist families, manage offices, transport students, provide technical support, and help create safe, welcoming schools for all. Soon, we will also celebrate our retirees, and I want to offer them my deepest gratitude. Many have spent the majority of their careers as part of the Charter Oak family. Year after year, they have given their time, talent, patience, and care to this district, shaping the lives of students in ways they may never fully know. Their service has strengthened our schools, supported generations of families, and helped build the district we are proud to serve today. To every employee, and especially to those we will soon honor for their years of service, thank you for your commitment, your heart, and your legacy. Because of you, Charter Oak truly is home.
