Corona del Mar High School ranked as the 40th best public high school in California in U.S. News & World Report’s rankings released this week.

Three schools in Irvine cracked the top 100 statewide again this year: University High at 46, Northwood High, at 68, and Beckman High, at 74. University and Northwood are in the Irvine Unified School District, and Beckman is in the Tustin Unified School District.

Troy High School in Fullerton came in 69th – up from its 97th spot last year. Orange County School of Arts, in Santa Ana, placed 72nd in the state, four paces ahead of its No. 76 ranking last year.

Noticeable in its absence was Oxford Academy in Cypress, a magnet school that has consistently ranked among the top schools in the state and even in the nation for the past decade.

“We believe there was some kind of glitch,” said Michael Matsuda, superintendent for the Anaheim Union High School District.

There were no drops at Oxford in any of the metrics the magazine considers, and in some cases, Oxford ranked even higher, Matsuda said. Last year, the school was second best in the state, and 16th best in the nation.

U.S. News was unable to compute the school’s college-readiness index because Common Core data collected by the U.S. Department of Education’s National Center for Education Statistics did not include necessary information, such as grade 12 enrollment numbers, said Robert Morse, chief data strategist at U.S. News.

Other Anaheim Union districts schools that typically garner silver and bronze medals got none this year and according to the rankings, some of the data also appears to be missing from the magazine rankings published online, said Manuel Colón, the district’s chief academic officer.

Only two of Anaheim Union district’s high schools netted a silver medal: Kennedy, ranked 298 in the state, and Cypress, ranked 236.

No Orange County school ranked among the top 100 nationally.

Whitney High School in neighboring Cerritos ranked top in the state and 19th best in the country.

Another area school that ranked high was the California Math and Science Academy, part of the Long Beach Unified School District, which came in as 10th best school in the state.

The magazine evaluated nearly 20,000 schools in 50 states and the District of Columbia.

Analysts looked at various measures, including whether each school’s students were performing better than statistically expected for students in that state and whether disadvantaged students – black, Hispanic and low-income – were outperforming disadvantaged students in the state.

Another consideration was how well schools prepare students for college, based on scores of Advanced Placement or International Baccalaureate exams. For the first time, graduation rates were added as a measure.

“Parents should look at multiple indicators always … but certainly the U.S. News and World Report is another benchmark of how healthy a school district or specific school is,” Matsuda said. “In this case … there was a mistake.”
