Magnet Schools Directory
The largest US magnet school by NCES enrollment is Tucson Magnet High School in Tucson, AZ, with 3,162 students. The 100 largest magnet schools span 23 states and skew toward secondary campuses (36 high schools).
The 100 schools below are the largest US magnet schools by total enrollment, drawn from the NCES Common Core of Data using the federal magnet status flag. Where the school\'s district has reported math and reading proficiency to EDFacts, we display the district-level rate as a uniform descriptor. The Urban Institute Education Data API wraps the same fields for researchers building analyses at scale.
Tucson Magnet High School in Tucson, AZ enrolls 3,162 students, well above the U.S. median for its level and large enough that staffing, scheduling, and bus logistics differ in kind from smaller schools. It heads a list spanning 23 states.
100 Largest Magnet Schools by Enrollment
What This Ranking Measures
This page lists magnet schools as flagged in the NCES Common Core of Data. Sorting is by total enrollment. Magnet status reflects programmatic intent (a themed curriculum drawing district-wide enrollment), not academic outcomes.
Magnet schools are district-run public schools with a specialized theme — STEM, arts, dual-language, IB, career-technical — designed to draw students from across attendance boundaries. Admissions are typically lottery-based, sometimes blended with academic criteria. Because magnets self-select families who actively chose the program, raw proficiency comparisons against neighborhood schools should be read with that selection effect in mind.
Across the 100 magnets listed, the level breakdown is roughly 9 elementary, 55 middle, 36 high, and 0 configured as Other — usually comprehensive K-12 themed academies. Among magnets with published EDFacts results, a district-level rate close to the national middle, where roughly half of tested students reach grade-level standards on EDFacts assessments.
How to Read These Numbers
Magnets that consistently top enrollment lists are usually long-standing district anchors — schools with a defined theme, a multi-decade waitlist, and reliable funding renewal. Big enrollment also means more diverse course offerings within the magnet theme: a 3,000-student STEM magnet can run a full sequence of AP science courses plus engineering and computer science specializations that a 500-student themed academy cannot match.
Reading proficiency rates on a magnet list requires extra caution. Magnets self-select families who chose the program, and many use lottery + academic criteria for admission. That selection effect shows up in proficiency comparisons. Don\'t infer that "magnets are better than neighborhood schools" from these numbers — the comparable populations are not the same.
A few honest caveats: EDFacts proficiency and graduation rates are reported at the district level, not the individual school. We apply the district number to every school in that district so that the comparison is at least consistent — but a strong school inside a struggling district will look worse than it is, and vice versa. NCES publishes the most recent year of CCD data with about a one-year lag. Privacy suppression hides results for very small subgroups, which appears as missing data rather than zero.
Methodology
We filter NCES CCD to schools where the magnet status flag is set, sort by total enrollment, and keep the top 100. We do not modify the federal numbers or fold in district-level magnet directories outside CCD. EDFacts proficiency is joined at the district level. The full data lineage lives on the methodology page.
Frequently Asked Questions
What is the largest magnet school in America?
Tucson Magnet High School in Tucson, AZ, with 3,162 students enrolled, is the largest US magnet school in the most recent NCES Common Core of Data release. Young Magnet High School (2,148 students) is second.
What is a magnet school, exactly?
A magnet school is a district-run public school built around a specialized theme — STEM, performing arts, dual-language immersion, International Baccalaureate, career-technical education, classical liberal arts. The "magnet" name reflects the original purpose: drawing students from across district attendance boundaries to integrate enrollment and offer concentrated programming. Admissions are typically a lottery, sometimes blended with academic criteria. The NCES Common Core of Data carries a magnet status flag for every school the local district designates as a magnet.
How does a magnet school differ from a charter school?
Magnets are run by the local district under district employees and policies; charters are run by independent organizations under an authorizer-issued charter contract. Both are public, tuition-free, and typically lottery-admitted when oversubscribed. Magnets often offer a single themed program inside a larger district building; charters more often run a complete school as their own entity.
Are magnet schools academically selective?
It depends on the magnet. Some — especially exam-based STEM and humanities magnets — admit by test score and grades. Others admit by lottery with no academic threshold. Because admission rules differ across magnets, comparing raw proficiency rates between magnet and neighborhood schools without accounting for selection effects can be misleading.
Where are most large magnet schools located?
Big-district metros with active magnet programs — Chicago, Houston, Miami-Dade, Los Angeles, Charlotte-Mecklenburg, Wake County, Hillsborough — dominate the largest-magnet rankings. Many of these districts run magnets as a desegregation tool and as an alternative to charter expansion.
How current is the data?
NCES publishes the Common Core of Data with about a one-year lag. Magnet status flags reflect the most recent CCD release; this directory was regenerated in May 2026.
