San Dieguito Union High School District (SDUHSD) is a public school district based in northern San Diego County, California. Established in 1936, the district serves over 13,000 students in five middle schools, five comprehensive high schools, and one alternative high school.
Prior to 1936, students who lived in coastal North County attended high school in Oceanside. In January 1936, the communities of Encinitas, Cardiff, Solana Beach, Del Mar, Green Valley, and Olivenhain voted in favor to form a new high school district. San Dieguito Union High School, now San Dieguito High School Academy was the flagship school of the district, in which the first classes were held in September 1936. Architect Lillian J. Rice was hired by the district board to design the school.
The district now serves students from five elementary school districts in North County: the Encinitas, Rancho Santa Fe, Cardiff, Solana Beach, and Del Mar School Districts. Students from those school districts matriculate through the middle schools and high schools.
The district includes Encinitas, Del Mar, Solana Beach, portions of Carlsbad and San Diego, the Fairbanks Ranch and Rancho Santa Fe census-designated places, and most of the Elfin Forest CDP.
Feeder elementary districts include: Cardiff Elementary School District, Del Mar Union Elementary School District, Encinitas Union Elementary School District, Rancho Santa Fe Elementary School District, and Solana Beach Elementary School District.
The district is governed by a five-member school board, called the Board of Trustees. Since 2017, trustees are elected directly by voters from five separate areas within the district's boundaries.
The current board trustees include Rimga Viskanta, Jodie Williams, Jane Lea Smith, Michael Allman, and Phan Anderson. Williams and Smith are board president and vice president, respectively. Williams was elected to a first term, and Allman was reelected to a second term in November 2024. Anderson, Smith, and Viskanta were elected to the board in November 2022. Williams succeeds Katrina Young, elected to the board in 2020, after she announced she would not be seeking reelection in 2024.
Viskanta is a policy analyst, and former board member for the Encinitas Union School District. Williams is an attorney and former EUSD board member. Smith is a businesswoman, and former school teacher and administrator. Allman was former chairman, president, and CEO of Southern California Gas Company at Sempra Energy. Anderson is a software engineer.
The president of the board of trustees is Jodie Williams. She has served as president since December 2024. Williams previously was a member of the Encinitas Union School District board of trustees from 2016 to 2020. Anne Staffieri, former superintendent of the Escondido Union High School District, has served as superintendent since July 2023.
On May 10, 2023, the district announced in a press release that Anne Staffieri would serve as superintendent pending board approval of her contract beginning July 2023. Staffieri was superintendent of Escondido Union High School District from 2019 to 2023. Staffieri succeeds Tina Douglas, associate superintendent of business services, who had served as interim superintendent since April 2022.
Cheryl James-Ward, professor at San Diego State University and former CEO of E3 Civic High School, was hired in November 2021. James-Ward was placed on administrative leave in April 2022 after controversial comments she made about Asian Americans during a board workshop. Board trustees Muir, Allman, and Bronstein voted in favor, while Young voted against it. The board subsequently voted unanimously to terminate her contract on June 26, 2022, effective August 15, 2022, without cause.
The board appointed Lucile Lynch as interim superintendent in May 2021. She served in the role until the board hired James-Ward in November 2021. Lynch was preceded by Robert Haley, who served in the role beginning on November 1, 2018. He resigned in April 2021.
There are five high schools in the district, including four comprehensive schools and one alternative school. Although officially named academies, there is no official academic or educational difference between San Dieguito and Canyon Crest Academies and Torrey Pines and La Costa Canyon High Schools. SDUHSD uses school choice, which allows any student within the elementary and middle school boundaries to attend any of the four comprehensive high schools.
San Dieguito High School Academy (SDA), formerly San Dieguito Union High School, San Dieguito High School, and San Dieguito Academy, is the district's flagship school. Opening in 1936, the school is located in Encinitas around one mile from the coast. Similar to Canyon Crest Academy, SDHSA uses a semester class schedule, which allows students to take year-long courses in one semester. During the 2020-2021 school year, 2,059 students were enrolled.
Torrey Pines High School (TPHS) was established in 1974, located in the Del Mar Highlands area of San Diego.
