Sage Hill School:
Admission, Courses, and College Planning Guide

Sage Hill School is located in Newport Coast, Orange County, with its campus off Newport Coast Drive, between Newport Coast and Irvine. The school opened in 2000 and, according to its School Profile, was the first non-denominational, coeducational independent high school in Orange County, affiliated with neither the government nor any church. According to the School Profile 2025-2026, the school enrolled 597 students in grades 9 through 12 that year; grades 7 and 8 are added from 2026-27, and the school plans an enrollment of about 700 in grades 7 through 12. Three features stand out: upper school classes average 14 students, with a student-to-college-counselor ratio of 36:1; mathematics runs as far as Multivariable Calculus and Linear Algebra; and the school’s weighting rules almost match the UC rules, differing by only two courses. This page does not rate the school. It answers two questions: how to gain admission to the school, and how to plan once enrolled.

UC A-G refers to the seven subject areas (a through g) that the University of California and the California State University require of high school students; UC recognizes only the courses on a school’s A-G list. AP (Advanced Placement) is the College Board program of college-level courses, Honors courses are advanced courses designed by the school, and Post-AP courses are the level beyond AP.

The College Preparation Profile of Sage Hill School

The data the school publishes point to four characteristics.

First, the school is small and counseling is close. In 2025-26, grades 9 through 12 enrolled 166, 150, 139, and 142 students. The School Profile lists a college counseling office of 7 staff members, and the school states a student-to-college-counselor ratio of 36:1. The school does not compute class rank, citing its competitive admission and relatively small enrollment.

Second, the course ceiling is high. The school offers 20 AP and 3 Post-AP courses. Beyond AP Calculus, mathematics continues with Calculus C, Multivariable Calculus, Linear Algebra, and Advanced Topics in Mathematics. At the same time, the school strongly recommends that students take no more than 3 honors and AP courses combined each year; a schedule with more than 3 requires a parent-signed acknowledgment.

Third, standardized test scores are high. According to the School Profile, for the classes of 2024 through 2026, as of July 2025, the middle 50% SAT range was 1380 to 1530 (235 test takers, mean 1435), and the middle 50% ACT composite range was 30 to 35 (181 test takers, mean 32). The class of 2025 had 22 National Merit Semifinalists and 42 Commended Students, which the school describes as its largest number of Commended Students. The National Merit Scholarship Program selects students based on grade 11 PSAT scores.

Fourth, required programs outside the classroom run every year. Service Learning and Spring at Sage, the end-of-year seminar and travel program, are required every year from grade 7, and upper school students must also complete 4 Sage Center Designated Courses. The school has no religion courses.

How to Apply to Sage Hill School

The main entry points at Sage Hill School are grade 7 and grade 9; openings in grades 10 through 12 are very limited. The steps below follow the school’s published schedule for 2027-28 entry. The process is the same for grade 7 and grade 9.

The school’s public pages do not state the application fee or the date admission decisions are released. The relationship between aid and admission deserves attention: the school states that the admission committee does not consider whether a family applies for aid, but in years when the aid budget is insufficient, admission may be more selective for students who apply for aid.

Below are the 2027-28 application dates published on the school website, followed by EDUBUS advisors’ review of the application to this school.

UC Applications Year by Year: Counts, Admission Rates, and GPA

The data below come from UC Infocenter, published by the University of California Office of the President, reported by source high school under the California private high school category and updated annually. They answer two questions: how many Sage Hill School students apply and are admitted each year, and what GPAs admitted students hold. GPA is the UC weighted, capped GPA, which counts only courses from grades 10 and 11. UC does not publish categories with fewer than 5 applicants or fewer than 3 admits or enrollees; these appear as a dash (—) in the tables.

Applications and Admits by Campus, Most Recent Year

Campuses are listed in order of the U.S. News national university rankings. UC leaves a category blank when it has fewer than five applicants or fewer than three admits or enrollees.

College Destination Lists Published by the School

All content in this section comes from two lists that Sage Hill School publishes itself, compiled by the school, covering the classes of 2023 through 2026. Note the basis: the School Profile list includes every college that admitted a student, but only the colleges in bold had students enroll, and the numbers in parentheses are enrollment counts. The figures in the table are therefore three-year enrollment totals, not admission counts.

These two lists show two things. First, private university enrollment concentrates in a few institutions: across the classes of 2023 through 2025, 25 students enrolled at New York University, 16 at Stanford University, and 15 at the University of Southern California. Second, out-of-state colleges account for a large share: the school reports that only 40% of its 2022 through 2025 graduates attended college in California, with the rest spread across the Mid-Atlantic, the Midwest, the Northeast, and other regions. These are enrollment outcomes and cannot be used to estimate admission counts or admission rates at any particular university. For UC applications, admissions, and enrollment, the official UC data on this page are authoritative.

GPA Weighting: School Rules and UC Rules

This section addresses the calculation parents most often get wrong: how the school and UC each weight the same transcript. The school’s rules come first.

A course-by-course check against the official UC A-G list shows that the following courses are weighted as honors at Sage Hill School but are not on the UC-approved honors list; they count as regular courses in UC applications.

At Sage Hill School, the two systems differ very little in which courses they weight: of the 46 courses weighted at school (20 AP and 26 non-AP courses), 44 are also UC-approved honors courses, including Post-AP courses such as Multivariable Calculus, Linear Algebra, and 9 honors arts courses. The only course that requires real attention is Honors Algebra II and Trigonometry: if a student who starts in Geometry takes this course in grade 10, it raises the school GPA but adds nothing to the UC GPA. The larger difference lies in grading. The school uses plus and minus marks, so an A- counts as 3.67; UC ignores plus and minus marks, so both A- and A count as 4, and UC does not count grade 9 grades. The school GPA and the UC GPA can therefore differ considerably, and not always in the same direction. EDUBUS recommends that grade 10 schedules give priority to UC-approved honors courses, such as Honors Biology, AP World History, or AP Chemistry. UC counts at most 4 honors points in grade 10, which equals two full-year honors courses and fits the school’s recommendation of no more than 3 per year.

Timeline from Grade 7 to Grade 12

Three decision points shape the path. The first is the math and world language placement tests in April of the entry year, which set the math starting point and language level at entry and determine whether the student can reach AP Calculus in grade 10. The second is course selection in the spring of grade 10: Honors English 11 requires an A- writing average in English 10, and honors world language courses open only from grade 10. The third is grade 11: the school assigns each student a college counselor that year, and it is also the last year counted in the UC GPA. Students who enter in grade 7 have one more decision point: advancing in mathematics to Geometry or Algebra II during the two middle school years, so that no placement test is needed on entering grade 9.

Clubs and Academic Competitions

The school’s academic teams and clubs page states that Sage Hill School has more than 90 clubs each year; students may start their own clubs, each advised by a faculty or staff member. Student clubs with an academic or professional focus in 2025-26 include:

• Sage Hill Math Meet
• USABO & BBO Club (USA and British Biology Olympiad)
• ChemClub
• Quantum Club
• Science Scholars
• Sage Hill American Rocketry Club (SHARC)
• Micromouse Club
• Women in Engineering Club
• Youth Engineers Initiative
• AI and VR Innovation Club
• 3D Modeling and Design
• Coding for Equality
• MedX, Med-Talk, NeuroNex, GIDAS (medicine and neuroscience clubs)
• Business Club, Girls for Business, Marketing in Motion (business clubs)
• Sage Hill Chess Club
• Stoic Society
• Writing Club, Youth Prose Scholars (writing clubs)

The school also has academic teams led by coaches that require a larger time commitment and compete against schools across Orange County and California.

• Academic Decathlon: students compete on individual scores in art, language and literature, mathematics, music, science, and social science
• Science Olympiad
• Speech and Debate: competes from September through April in World Schools, Public Forum, and Lincoln-Douglas formats
• Model United Nations: founded in 2011
• Mock Trial
• Robotics
• DECA business competition team (Distributive Education Clubs of America)
• Junior Classical League
• Student newspaper The Bolt and yearbook Storm

Note that the school’s academic teams focus mainly on team competitions, and the math club and biology olympiad club are student-initiated clubs rather than school-led teams. Students who want to demonstrate ability through individual competition results, such as the American Mathematics Competitions (AMC) or the USA Biology Olympiad (USABO), need systematic training outside school.

Signature Programs

• Spring at Sage (end-of-year seminars and travel): Each year after AP and final exams, all students and teachers spend about a week in on-campus seminars or domestic and international travel; the program is required and credit-bearing every year in grades 7-12. Grade 7 takes part only in on-campus and local seminars, grade 8 may choose travel within California, and grades 9-12 may choose domestic or international travel (North America only for grade 9). The school's FAQ states that the program has visited 46 international destinations. The 2026-27 dates are May 24 to June 1, 2027
• Service Learning: Required and credit-bearing every year in grades 7-12; 6 of the 8 Sage Center Days each year are full days devoted to Service Learning. Each grade has its own theme: grade 7, foundations of service; grade 8, environmental responsibility; grade 9, understanding the Orange County community; grade 10, partnering with fourth graders at a partner elementary school; grades 11 and 12 may propose independent projects or join teacher-led projects
• Sage Hill Internship Program (SHIP): Grade 9 students may apply to the Pre-SHIP leadership program; students in grades 10-12 may voluntarily take SHIP Prep Level I and Level II, which include resume review, mock interviews, and career talks, and those who complete them receive a list of internship and job-shadowing opportunities in the Orange County area in April. The school states that 140 students completed the program the previous year
• Sage Center Designated Courses (SCD): Courses that build six competencies (the Six Cs): critical thinking, collaboration, communication, cross-cultural competency, creativity, and character, into instruction and assessment; some include Service Learning or off-campus fieldwork. Four are required for graduation
• Post-AP courses and Independent Study: Mathematics and computer science offer 3 Post-AP courses: Multivariable Calculus, Advanced Topics in Mathematics (introduction to proofs, set theory, number theory, and group theory), and Advanced Topics in Computer Science (C# and game development). Students in grades 11 and 12 who have completed all courses in a subject may apply for a year-long Independent Study, which earns a letter grade and one semester of credit on completion but does not count toward graduation requirements
• Sage Connected blended online courses: Online learning combined with regular in-person sessions on campus, open only to grades 11 and 12; a Sage Connected course may serve as a sixth or seventh course, limited to one per school year. In 2026-27 the offerings are the creative writing course Storytellers' Workshop and 3D Design, Modeling, and Fabrication
• Arts: The 30,000-square-foot Studio arts building includes a digital art lab, ceramics studio, instrumental, choral, and dance rooms, and a black box theater. New grade 9 students first take Arts Survey; students in grades 10-12 may enter honors arts courses by audition or portfolio review. Honors arts courses are weighted at the school and are also recognized as honors courses by UC
• Middle School (new in 2026-27): The first grade 7 and 8 students arrived on August 17, 2026. The Middle School has its own academic building, dining hall, and the Bolen Family gymnasium. Middle School students also take part in Service Learning and Spring at Sage, and choose from 16 electives including Model UN, debate, robotics, computer science, and Junior Classical League

Choosing a School: Total Tuition, Commute, and Visits

This section answers five questions parents often ask when choosing a school: which families the school suits, how much tuition totals through graduation, how students get to school from Irvine, what to ask during a visit, and which nearby schools are worth comparing.

Which Families the School Suits

Total Tuition Through Graduation

At 2026-27 tuition rates, attending from grade 7 through grade 12 takes 6 years: 2 middle school years at $49,500 per year and 4 upper school years at $58,100 per year, for total tuition of $331,400. Entering in grade 9 and attending for 4 years totals $232,400 in tuition. Tuition usually rises each year, so the actual total may exceed figures based on current rates. These amounts exclude the school bus, AP exam fees, and extracurricular program costs; the enrollment deposit is credited toward the first tuition payment and is not an additional cost. For families who apply for Flexible Tuition, the school sets the amount actually paid based on family finances.

Commuting from Irvine

The Sage Hill School campus is on Newport Coast Drive, close to southern Irvine. The table below shows straight-line distances to the school from several Irvine neighborhoods with large Chinese American communities, measured by EDUBUS from each neighborhood’s center point to the school address; actual driving times depend on navigation.

Both fee-based bus routes arrive at school at 7:30 a.m. The stop closest to Irvine is at Jamboree Road and El Camino Real on the Santa Ana and Tustin route; families in other neighborhoods need to drive or carpool. EDUBUS recommends driving the route once during the morning arrival window on the day of a school visit.

Questions to Confirm During a Visit

The school’s public pages do not clearly answer the following questions, so families should confirm them in person during a visit or meeting.

• Application fee: the How to Apply, Admission Overview, and FAQ pages do not state it.
• Decision release date: the website publishes only the January 31, 2027 deadline, not the date decisions are released.
• Actual 2026-27 enrollment and middle school class sizes: the FAQ page states only a planned enrollment of about 700, and two pages give the average middle school class size as 14 and 16, respectively.
• Whether outside math courses can be used for advancement: the course catalog states that outside math courses other than Geometry are not used for advancement, while the school handbook requires prior written approval from the department chair.
• Costs beyond tuition: AP exam fees, school bus fees, and fees for the Summer at Sage credit courses.

Comparable Schools

Private schools in Orange County near Sage Hill School that serve the same or similar grades include the following; the main differences lie in religious affiliation and admission testing.

• Pacific Academy Irvine: in Irvine; also serves grades 7 through 12 with no religious affiliation; admission is based on an interview and writing, and students whose first language is not English take the iTEP.
