The school also has an agricultural area with livestock, a garden, a cafeteria, multiple computer labs, a woodshop, two music rooms, a football field, a staff parking lot, and a student store.

In the 1950s, many smaller construction projects took place, including the agricultural classrooms, the boys' gymnasium, the home-side bleachers and the instrumental music room.

In 1973, the Amelia Earhart Continuation High School was built on the campus' northeast corner.

In the late 1990s, thirteen modular buildings were installed to support an increase in the number of students.

Several NHHS parents and community members did not want a year-round schedule since they feared it would negatively impact the Highly Gifted Magnet.

[4] According to the 1996 scheduling magnet, students were supposed to get July–May, which would have affected their ability to attend summer programs operated by Ivy League universities.

[9] In 2007, the traditional calendar was re-adopted and the students were divided into many Small Learning Communities (SLCs).

[11] In 2018, there was a proposal to co-locate a charter school, Valley International Preparatory High School (VIPHS), on the NHHS campus, but there was student opposition; students created an online petition to oppose the co-location.

The students in the HGM are from all over Los Angeles, and have a variety of extracurricular interests, as well as diversity in their academic directions.

If there are openings remaining in the program, “Gifted” students with 99.5%-99.8% may be admitted with priority based on magnet points.

Many of these classes include fieldwork in the Los Angeles Zoo and Botanical Gardens, Los Angeles River ecosystem, Autry National Center and the natural world of Griffith Park for tours and observation.

The STEM Magnet was established in 2018, and is an alternative course of study that prepares students for college and career opportunities in Science, Technology, Engineering, and Math.

The HSAS is designed for identified gifted, high achieving, high-ability students who show an interest in taking Honors and Advanced Placement courses.

NHHS was awarded an overall grade of "A+", with an A in Academics, an A in Diversity, an A+ in Teachers, an A in College Prep, a B+ in Clubs and Activities, a B in Administration, a B− in Sports, a B- in Food, and a C+ in Resources and Facilities.

[22] For the 2017-18 school year, the average ACT Test scores were a 25 in Reading, a 25 in English, a 24 in Math, and a 24 in Science, each out of 36 points.

"[31] NHHS offers 25 Advanced Placement courses in biology, calculus AB, calculus BC, chemistry, computer science A, computer science principles, English language and composition, English literature and composition, environmental science, European history, French language, human geography, macroeconomics, music theory, physics 2, physics C: electricity and magnetism, physics C: mechanics, psychology, Spanish language, Spanish literature, statistics, studio art, US government and politics, US history and world history.

The NHHS Huskies compete in the CIF Los Angeles City Section's East Valley League.
