Original Research by School Decision on Troy High
Troy High is a mid-sized regular public high school in Fullerton serving grades nine through twelve. The school's enrollment is evenly distributed across its four grades, with families drawn from across the attendance zone.
The student body at Troy reflects Fullerton's demographic character. A substantial majority of students identify as Asian, with meaningful Hispanic and mixed-race populations present as well. About two-fifths of students qualify for free or reduced-price lunch, indicating a moderately economically diverse cohort with real economic need alongside families with greater resources.
On state testing, Troy performed solidly in 2024-25. Students demonstrated strong English language arts proficiency, with the great majority meeting or exceeding standards. Mathematics proficiency was also substantial, with about three-quarters meeting the bar. Science proficiency, while respectable, was the lowest of the three tested subjects, running somewhat behind math and ELA. The school currently has data only from this single recent year, so trend information is not available.
Fullerton itself is a mixed-use city with an educational identity. It sits at the convergence of California State University, Fullerton and Fullerton College, anchored by a major transit hub in its downtown. The city has shifted from its agricultural and mid-century aerospace manufacturing roots into mixed residential and commercial development, with stronger walkability in its downtown core and older neighborhoods, and car-dependent residential tracts in the north and west. Housing values are elevated relative to national averages, with monthly rents substantial as well. The housing market reflects broader Orange County and Southern California conditions, where affordability remains a constraint for many families.
The Fullerton Joint Union High School District, Troy's parent district, has pursued facilities investment through bond measures. Voters approved a substantial bond in November 2024 that will fund construction and repairs across district schools. This bond will be repaid through a property-tax increase, adding to homeowners' tax bills over many years and following earlier facilities bonds the district is still repaying. Parents considering the area should account for this ongoing property-tax commitment when evaluating housing costs.
The district is also implementing California law AB 2319, which bars Native American mascots. Fullerton Union High School (a companion school in the district) is retiring its longtime "Indians" mascot in favor of "RedHawks" beginning in 2026-27, a change that reflects both the legal requirement and the district's shifting traditions.
State assessment data for graduation rate and chronic absenteeism was not available, so a parent may want to look into those measures directly with the school or district. Data on the school's special education and English learner populations was also not reported. Program offerings, staffing depth, course availability, and discipline records were similarly not available in the source materials. These attributes would be worth exploring in conversation with the school's counselors and administrators.
