Troy High School is located in the city of Fullerton, next to California State University, Fullerton, and belongs to the Fullerton Joint Union High School District (FJUHSD). Enrollment in the 2026-27 school year is 2,394 students. What sets the school apart is not its size but its structure: it runs a STEM magnet program that includes nearly three-quarters of the student body, along with three independent advanced course systems, AP, IB, and Cambridge. This page does not rate the school. It answers one question: how a student at this school should plan the four high school years.
How Troy High School Is Structured for College Admissions
Public data point to four features of this school.
First, a high share of students take AP exams. In May 2026, 1,643 students took 4,291 AP exams, with an average score of 4.13, and 94.6% earned a 3 or higher. Measured against total enrollment of 2,394, roughly seven in ten students took an AP exam that year, and each test taker took an average of 2.6 exams.
Second, three advanced systems coexist. In addition to 27 AP courses, the school has offered the IB Diploma Programme since 1986 (12 courses) and Cambridge International A Level courses since 2020 (13 courses). In 2026, students took 296 IB exams with a 95.7% pass rate and 297 Cambridge exams with a 97.8% pass rate. The three systems are not three parallel tracks but intersect with one another: a single course often corresponds to AP, IB, and Cambridge exams at once, and students decide which system to follow when selecting courses in grade 10.
Third, the weighting rules are more generous than in Irvine. Honors, AP, and IB courses are all graded on a 5.0 scale, and the school’s School Profile includes Cambridge courses as well. This means that choosing honors courses in grade 9 already raises the school’s weighted GPA, entirely different from the Irvine Unified School District practice of adding weight only for AP courses.
Fourth, the absolute number of UC admits is large. For fall 2025, 406 Troy High School students applied to the University of California, and 343 were admitted to at least one campus, a systemwide admit rate of 84.5%; UC Berkeley admitted 52 of them. Among the ten Orange County and Irvine public high schools covered on this site, this Berkeley admit count ranks first; the highest among the five Irvine public high schools is 34.
How to Get Into This School
This is the first question Troy High School parents ask, and it is also where misunderstandings are most common. The conclusion first: students within the attendance area enroll directly without an exam; the exam decides whether a student can enter the Troy Tech magnet and grade 9 honors courses.
Route 1: Students Within the Attendance Area
- Assigned directly by the Fullerton Joint Union High School District based on home address, with no exam and no application
- Students who want to enter the Troy Tech magnet program or grade 9 honors courses must still take the January placement exam in grade 8
- Families who do not plan to pursue Troy Tech can skip the exam entirely, enroll as usual, and take AP courses
Route 2: Students Within the District but Outside This Attendance Area
- Apply to transfer during the Open Enrollment window each January. For the 2026-27 school year, the window ran from January 12 to January 30, 2026
- Submit the application at the student's assigned high school with proof of residence (a utility bill plus a lease or mortgage statement)
- Admission is subject to available space; students who also want to enter Troy Tech must still take the January placement exam
Route 3: Students From Outside the District
- In grade 8, take the Troy Tech / IB / Cambridge / Honors placement exam, which is open to all grade 8 students regardless of district
- After admission, return to the high school of residence to obtain an inter-district permit
- The inter-district permit must be renewed every year and expires at the end of each school year; it may be revoked for poor attendance, misconduct, poor academic performance, or lack of space in the grade level, although agreements for grades 11 and 12 are not revoked midway
- The district does not provide school buses, and parents are responsible for transportation to and from school
| Exam content | Math and English at the mid-year grade 8 level, with multiple-choice questions plus one English essay |
|---|---|
| Exam time | Check in at the North Gym at 7:15 a.m.; the exam runs from 7:30 to 11:45 |
| Materials to bring | Student ID or passport, and a printed grade 8 class schedule showing the current math course |
| Registration and exam dates | Admission for the 2027-28 school year (8th-grade students in 2026-27): online registration runs from December 1, 2026 to January 27, 2027; applicants choose one of three test dates (January 16, 23, or 30, 2027); all applicants are notified by email by March 1, 2027, and acceptance emails include the March registration dates and procedures |
| Information sessions and tours | Troy Tech Visitation Day on December 2, 2026, from 4:00 to 5:00 p.m.; a Troy Tech / IB / Cambridge information night in the North Gym on January 20, 2027, from 5:00 to 6:00 p.m., followed by an open house from 6:00 to 7:30 p.m.; campus tours by appointment on November 3, 10, and 17 and December 1, 2026, from 9:00 to 11:00 a.m. |
| Where students come from | Troy Tech students come from four counties: Orange, Los Angeles, Riverside, and San Bernardino |
| Requirements to remain enrolled | Once enrolled, Troy Tech students must meet continuation requirements every semester: an unweighted GPA of at least 2.0 each semester; at least 25 credits per semester for students on a six-period schedule, or at least 30 credits for students on a seven-period schedule; enrollment in a Troy Tech course every semester in grades 9 through 11, and completion of the internship course in grade 12 (or the summer before grade 12). Failing any Troy Tech elective makes a student ineligible. There is no probation period for poor attendance; a first disciplinary violation results in disciplinary probation and a second results in exit from the program. Students who exit may not rejoin |
Ten Years of UC Application Data: Applicants, Admit Rates, and GPA
The following data come from UC Infocenter, published by the University of California Office of the President. The data are reported by high school of origin and updated annually. They answer two questions: how many Troy High School students apply to and are admitted by the University of California each year, and what GPA admitted students hold. GPA is the UC weighted, capped GPA, which counts only courses taken in grades 10 and 11.

GPA Weighting Rules: The 5.0 Scale and Deciles
| Weighting rule | Standard courses are graded on a 4.0 scale (A=4, B=3, C=2, D=1, F=0); Honors, AP, and IB courses are graded on the district's 5.0 scale (A=5, B=4, C=3, D=1, F=0). The school's School Profile also places Cambridge courses on the 5.0 scale |
|---|---|
| Weighted courses | All Honors courses; All AP courses; All IB courses; Cambridge courses (per the School Profile) |
| Treatment of D and F | A D earns only 1 point and an F earns 0 points on both scales, so weighting applies only to A, B, and C grades. As a result, a C in a weighted course earns the same grade points as an A in a standard course |
| Class rank | The school does not publish individual class rank, but its School Profile lists the weighted GPA range for each of the ten deciles of the Class of 2027, so college admission officers can gauge a student's standing within the school |
| Repeating a course | When a course is repeated, both the original and the new grade remain on the transcript and both count toward the district GPA. Credits earned by repeating a course count only as elective credits and cannot satisfy a subject's minimum credit requirement a second time |
| Outside grades | Grades earned outside the district's regular high school courses do not count toward GPA; credits from principal-approved community college Special Admit courses are not recorded on the high school transcript |
This rule shapes course selection and also sets the strategic difference from Irvine high schools. In the Irvine Unified School District, honors courses are not weighted, so grades in grades 9 and 10 do not create much separation; at Troy High School, English 1 Honors, Geometry Honors, Algebra 2 Honors, and Biology Honors are graded on the 5.0 scale starting in grade 9, and the difference accumulates substantially over four years. The other side should also be noted: weighting applies only to A, B, and C grades, and a D earns only 1 point on both scales. A C in a weighted course earns the same grade points as an A in a regular course, so “forcing an advanced course for the weighting” is not worthwhile.
The table below shows the class of 2027 deciles published in the School Profile, which can be used directly to compare the student’s current weighted GPA.
| Decile | Weighted GPA range |
|---|---|
| Decile 1 | 4.90-4.76 |
| Decile 2 | 4.75-4.63 |
| Decile 3 | 4.62-4.48 |
| Decile 4 | 4.47-4.27 |
| Decile 5 | 4.26-4.00 |
| Decile 6 | 3.98-3.70 |

Three milestones actually determine the direction: the placement exam in January of grade 8, which decides entry into Troy Tech and grade 9 honors courses; the choice between IB and Cambridge during course selection in grade 10, which is the decision point officially designated by the school; and completing the Pre-Internship and earning a recommendation in grade 11, which is required to enter the 150-hour senior internship in grade 12. The first two are essentially impossible to recover from if missed.

It should be noted separately that the best-known competition programs at the school are not on the club list; they operate as school teams or as Troy Tech pathway courses.
- Science Olympiad: 28 state championships and 14 national championships since 1996
- Troy Cyber: the largest high school cybersecurity program in the nation, with five national championships (2018, 2019, 2021, 2023, 2024) and 4 All-Americans, including Charissa Kim in 2020, the first female All-American in the nation; the coach has twice been named CyberPatriot Coach of the Year (2016, 2023)
- NJROTC: 477 cadets; the nation's Most Outstanding Unit and national champion in 2026, winning the NJROTC national academic, athletic, and drill competitions as well as the CyberPatriot All Service Division and All Service Drone Division
- FBLA: part of the Troy Tech Business pathway; competes each year at the state competition and the National Leadership Conference
- FIRST Robotics: competes in the national build competition
This means the entry points differ: joining Science Olympiad or Troy Cyber goes through tryouts and course selection, not club sign-up. FBLA (Future Business Leaders of America; part of the Troy Tech Business pathway and not on the ASB club list); Science Olympiad (run as a school team and not on the ASB club list); Troy Cyber (run through the Troy Tech Cyber Defense pathway and as a school team).
Signature Programs
- Troy Tech Magnet Program (since 1986): The first magnet program in Orange County, founded with a California Specialized Secondary School grant as a four-year STEM program. It enrolls about 1,750 students, 73% of the school, drawn from four counties: Orange, Los Angeles, Riverside, and San Bernardino. Each year students take one additional course from one of six pathways (Media, Business, Computer Science, Cyber Defense, Engineering, and Governmental Leadership). All 9th graders begin with AP Computer Science Principles, and the program culminates in the Senior Internship
- Senior Internship: The capstone of Troy Tech: a 150-hour internship at a company or university, guided by a professional mentor, completed in person or online. In the Class of 2027, 389 Troy Tech students completed summer or school-year internships at 250 company and university sites, and the school's mentor database holds more than 1,000 contacts. In grade 11, students must first complete the Pre-Internship component and obtain recommendations from their teachers, the program coordinator, and administration; students with poor attendance or tardy records are not recommended
- IB Diploma Programme (since 1986): Twelve IB courses, offered in combination with Troy Tech. Diploma candidates must sit exams in 2 to 3 SL and 3 to 4 HL courses, and HL courses must be completed in grade 12; candidates also complete Theory of Knowledge, a 4,000-word Extended Essay, 18 months of Creativity, Activity, Service (CAS) plus a CAS project, and the Group 4 Collaborative Sciences Project each January. The school averages 75 IB Diploma candidates per year, with a 96% pass rate across 400 exams
- Cambridge International A Level and AICE Diploma (since 2020): Thirteen Cambridge courses, centered on A Level courses and exams, which is uncommon among Cambridge schools in the United States. The AICE (Advanced International Certificate of Education) Diploma requires a two-course sequence in each of three groups (Mathematics and Science, Languages, and Arts and Humanities), plus the core course Cambridge AS Global Perspectives & Research, and may be completed over four years. With strong A Level results, the University of California system recognizes up to 12 quarter units
- Navy Junior Reserve Officers' Training Corps (NJROTC): The home of the Troy Tech Governmental Leadership pathway, with 477 cadets. The unit holds the Navy's Distinguished Unit designation with Academic Honors and was named the nation's Most Outstanding Unit and national champion in 2026. NJROTC 1 is open to grades 9-12; NJROTC 3 and 4 are honors courses and count toward UC A-G category g (elective)
- AVID: AVID 1 through 4 correspond to grades 9 through 12 and count toward UC A-G category g (elective). The program serves students who aim to attend a four-year college and need support with study skills and college preparation
- Dual Enrollment with Fullerton College and Cypress College: Both community colleges offer free dual enrollment courses, taken at the college, online, or on the high school campus; credits transfer to the California State University and University of California systems (Cal-GETC applies). The school states explicitly that dual enrollment courses are an additional enrichment opportunity only: they do not earn high school credit, do not affect high school GPA, and do not satisfy graduation or UC A-G requirements
How to Use the Counseling Office
| Counselors and platform | Five counselors divide students by last-name initial (Class of 2027), and there is also a registrar. The school's college planning page provides instructions for CaliforniaColleges.edu; grade-level slides from the registration presentations are posted in each counselor's Google Classroom, beginning with the in-class presentations each February |
|---|---|
| On-campus testing and registration | The PSAT/NMSQT will be held at Troy High School on Saturday, October 17, 2026, for 11th graders only, with 300 seats; registration is online through Total Registration in late August. AP exams take place in May 2027 at about $104 per exam (including the registration fee), with an additional charge for late registration; students in the federal free and reduced-price lunch program may apply for a fee reduction during the Aeries confirmation process before school starts. Cambridge exam registration takes place in mid-October each year, and the exam series runs from April 30 to June 12 |
| Schedule changes after school starts | Schedule changes after school starts happen in two stages: from August 10 to 3:00 p.m. on August 13, 2026, requests are submitted through the designated Google Form; after that the form closes and requests must be made in person during counselor drop-in hours. The district deadlines are 3:00 p.m. on August 28 (drops) and 3:00 p.m. on September 18 (level changes) |
| Transcripts | Transcripts are requested online through ScribOrder. Current students receive their first three copies free, and each additional copy costs $5; requests by phone, email, fax, or mail are not accepted. Requests are processed on regular business days and take 2 to 3 business days; delivery outside the United States costs an additional $10 |
| Community college dual enrollment | Dual enrollment courses at Fullerton College and Cypress College are free, and credits transfer to the California State University and University of California systems, but they do not earn high school credit, do not affect high school GPA, and do not satisfy graduation or UC A-G requirements |

Frequently Asked Questions
Does a student who lives within the Troy High School attendance area need to take an exam to enroll?
No. Students who live within the Troy High School attendance area are assigned directly by the Fullerton Joint Union High School District, with no exam and no application. The January exam decides a different matter: whether a student can enter the Troy Tech magnet program and grade 9 honors courses. Families within the attendance area who do not plan to pursue Troy Tech do not need to take the exam at all.
How can a student from outside the district attend Troy High School?
There is only one route: in grade 8, take the Troy High School Troy Tech / IB / Cambridge / Honors placement exam. For enrollment in the 2027-28 school year, registration runs from December 1, 2026, to January 27, 2027; the exam is offered on three dates, January 16, 23, and 30, 2027, of which the student chooses one, and results are emailed by March 1. After admission, a student from outside the district must return to the high school of residence to obtain an inter-district permit. The permit must be renewed every year, and families are responsible for transportation to and from school.
Irvine families should note: are honors courses weighted at Troy High School?
Yes. This is one of the biggest differences between Troy High School and Irvine high schools. Under Fullerton Joint Union High School District rules, Honors, AP, and IB courses are all graded on a 5.0 scale: an A earns 5 points, a B earns 4, and a C earns 3. The school's School Profile also places Cambridge courses on the 5.0 scale. As a result, taking courses such as English 1 Honors and Geometry Honors in grade 9 raises the school's weighted GPA on its own.
What GPA does a Troy High School student need to apply to the University of California?
According to official data from the University of California Office of the President, reported by high school of origin, the average weighted GPA of Troy High School students admitted for fall 2025 was: UCLA 4.28, UC San Diego 4.25, UC Berkeley 4.23, UC Santa Barbara 4.23, UC Irvine 4.22, and UC Davis 4.18. This is the UC weighted, capped GPA for grades 10 to 11. Ten years of year-by-year data appear in the UC data section of this page.
Does Troy High School have Science Olympiad and cybersecurity teams?
Yes, and both compete at the national level. Since 1996, the Troy High School Science Olympiad team has won 28 state championships and 14 national championships; Troy Cyber is the largest high school cybersecurity program in the United States and has won five national championships. Neither program appears on the list of 127 clubs registered with the Associated Student Body (ASB). Both operate as school teams and as Troy Tech pathway courses, so the entry point is course selection and team tryouts, not club sign-up.
Does Troy High School publish class rank?
It does not publish individual rank, but it does publish deciles. In its School Profile, Troy High School lists the weighted GPA range for each of the ten deciles in the class of 2027: decile 1 is 4.90 to 4.76, decile 5 is 4.26 to 4.00, and decile 10 is 2.15 to 1.28. College admission officers use these ranges to judge where a student stands within the school, and parents can also compare the student's current weighted GPA against them.
