Schools that finished in the top 40 percent of the national rankings qualified for a U.S. News "2019 Best High Schools" badge. EPHS ranked in the top 19 percent nationwide and top 22 percent statewide.
The publication released its 2019 results April 30. The rankings were based on data compiled from the 2016-17 school year.
U.S. News ranked 17,245 public high schools out of a review of more than 23,000 in all 50 states and the District of Columbia; the number of ranked schools is up from more than 2,700 last year.
To assemble its rankings, the magazine worked with North Carolina-based RTI International, a global nonprofit social science research firm. Together they used a revamped methodology that weighs six indicators of school quality:
► College Readiness
This is based on the proportions of 12th-grade students who took and passed Advanced Placement and/or International Baccalaureate exams.
► College Curriculum Breadth
This is based on proportions of 12th-grade students who took and passed AP and/or IB exams in multiple content areas.
► Math and Reading Proficiency
This is based on student performance on state-required tests.
► Math and Reading Performance
This is based on whether performance on state assessments exceeded expectations given the school's proportion of underserved students.
► Underserved Student Performance
This is based on how black, Hispanic and low-income students performed on state assessments compared with those who are not underserved in the state.
► Graduation Rates
This is based on the proportion of students who entered ninth grade in 2012-13 and graduated four years later.
The highest-ranked schools are those whose students excelled on state tests and performed beyond expectations, participated in and passed a variety of college-level exams, and graduated in high proportions.
