Northrup Field

THS Sports Pavillion


Founded in 1921 as Tustin Union High School because it served five elementary districts, Tustin High School was a stately two story structure surrounded by miles of orange groves and other agri-businesses, thus the school mascot, Tustin "Tillers". In 1966, construction crews rebuilt Tustin High to a one story sprawling campus to ensure the integrity of structures during a major earthquake.

The football stadium (newly renovated) was constructed at the 440 track in the mid-1940s. The stadium was later named “Northrup Field” after Orville Northrup, who taught woodshop and physical education, and served as Principal of Tustin Union High School from 1941-1962.

Today's campus consists of a renovated Plaza and Stage, new Humanities Building, Science Center, Sports Pavilion and remodeled Northrup Field. Our Special Ed, Math, and Social Sciences Wings, as well as the Little Theater, Library, Cafeteria and Administrative Offices were also renovated.

We genuinely appreciate the Tustin Community for supporting the Measure G and Measure L bond measures, which funded the building and modernization of these beautiful facilities on our campus. Every day our staff and students experience and are inspired by the culture and ambiance of a university/college campus right here in the City of Tustin.

Tustin High School is located on thirty-eight acres of land in the middle of the City of Tustin and houses the District football stadium. The campus also includes two baseball fields, two softball fields, two multi-use fields for football, boys and girls soccer and boys and girls lacrosse, six tennis courts, a 440 track, two gymnasiums for boys and girls basketball and boys and girls volleyball, and an Olympic-sized swimming pool.

Tustin Union High School District merged with Tustin Elementary School District on July 1, 1972, becoming part of Tustin Unified School District. A California Distinguished School, Tustin High has been recognized by Newsweek Magazine as one of the top High Schools in the US.

ERP Honor Roll

Red scroll with the words " ERP Educational Results Partnership, Honor Roll School, 2018-2019"



California School Recognized for High Achievement in Student Success by a National Campaign of Business and Education Leaders

Tustin High School has been named to the 2018 - 2019 Educational Results Partnership Honor Roll for its high achievement in student success. The program, sponsored by the Campaign for Business and Education Excellence (CBEE), is part of a national effort to identify higher-performing schools and districts that are improving student outcomes. Tustin High is one of 1,834 public schools in California to be recognized.

The 2018 - 2019 Honor Roll is developed by Educational Results Partnership (ERP), a nonprofit organization that applies data science to help improve student outcomes and career readiness. ERP maintains the nation’s largest database on student achievement and utilizes this data to identify higher-performing schools and districts. Schools that receive the ERP Honor Roll distinction have demonstrated consistent high levels of student academic achievement, improvement in achievement levels over time, and a reduction in achievement gaps among student populations.  For high schools, the ERP Honor Roll recognition also includes measures of college readiness.

“The Honor Roll is the only school recognition program in California based solely on objective achievement data,” said Marilyn Reznick, ERP’s board chair. “Schools don’t even know they’ve earned the honor until we tell them. Our goal is to guide other educators to data-informed best practices for raising student achievement.”

“ERP is all about improving educational equity and promoting career readiness for all students, regardless of their family income, background or ZIP code,” said James Lanich, Ph.D., ERP president and CEO.  “These Honor Roll schools and districts are living proof that our students can succeed when schools are committed to removing educational obstacles and accelerating student success. By focusing attention on these bright spots among our schools, we hope to change the conversation from ‘what’s wrong’ to ‘what’s working,’ and encourage others to replicate their success.”

In California, the ERP Honor Roll is supported by numerous businesses and organizations, including the Campaign for Business and Education Excellence (CBEE) Macy’s, Enterprise Holding Inc., the Auto Club of Southern California and, Wells Fargo.
