The Long Island High School for the Arts and the Doshi STEM Institute will hold an open house on their shared campus Saturday in an effort to boost interest in the schools that officials have said could face closure because of dwindling enrollment and falling tuition revenue.

Prospective students and their families may tour the facilities, meet with faculty and staff, and see the work produced by current students. Nassau BOCES, which operates both schools, is now accepting applications for the 2016-17 academic year.

The open house at 239 Cold Spring Rd., Syosset, is from 10 a.m. to 2 p.m.

Last month, Billy Joel announced a pledge of $1 million from his foundation to help save the arts school. On Monday, Joel will speak with students at the Hillwood Recital Hall in Tilles Center for the Performing Arts at LIU Post, for an “Afternoon of Questions & Answers . . . And a Little Music” to raise awareness of the school and encourage enrollment.

The students will come from both LIHSA, the only public high school arts program that serves students from across Long Island, and Long Island University. Other attendees will include superintendents and prospective students. The Long Island High School for the Arts has offered intensive training in the visual and performing arts for more than 40 years. Students from both Nassau and Suffolk counties are eligible to attend. Students may enroll in a half-day program, taking academic courses at their home high schools, or full-time, fulfilling all of their high school graduation requirements while perfecting their art.

LIHSA students receive professional-level training in dance, drama, filmmaking, instrumental and vocal music, theater technology, musical theater and the visual arts.

The Nassau BOCES Doshi STEM Institute is Long Island’s first science-centered high school, where students learn from expert science educators, and work with scientists and engineers from world-famous institutions, such as Brookhaven National and Cold Spring Harbor laboratories. Candidates are selected through a rigorous admissions process based on academic performance, extracurricular involvement, teacher recommendation and demonstrated interest in science, technology, engineering and math (STEM).

Doshi STEM students pursue a challenging course of study in engineering, research, robotics, mathematics, physics, chemistry and biology. The Institute’s curriculum surpasses the New York State Common Core to cultivate students’ knowledge and skills in the STEM disciplines, and to prepare them for college and career. Classes are taught by dually certified instructors, and students regularly collaborate with professional scientists, technicians and engineers through partnerships with industry leaders and vital resources, such as the Long Island STEM Hub, as well local colleges and businesses.
