U.S. News & World Report has published its 2016 ranking of the nation's best public high schools. The rankings were based on data from 28,561 public high schools and from that total, 19,908 schools with high enough enrollment and sufficient data to be ranked.

The methodology for the ranking process was to 1) identify schools that best serve students' needs, including disadvantaged subgroups, based on academic performance in reading and math and 2) evaluate college preparedness based on graduation rates and participating and performance on Advanced Placement (AP) or International Baccalaureate (IB) exams.

The median College Readiness Index (CRI) for 2016, measured on a scale of 0 to 100, was 20.17. A CRI of 100 means that all 12th graders took and passed at least 1 Advanced Placement or International Baccalaureate test.

Among other factors, to be ranked, a high school had to perform better than expected on state accountability assessments, factoring in the proportion of economically disadvantaged students.  In other words, to receive a ranking, a school had to perform higher than other schools in the state with similar proportions of economically disadvantaged students.

To be ranked in California, schools must receive either a gold (top 500 nationally) or silver (top 501 to 2,673 nationally) medal, representing schools with CRI values at or above the 20.17 median.
