Once again, Oakland’s American Indian Public Charter High has topped the Washington Post‘s list of the nation’s most challenging high schools. The index measures the percentage of students taking a college-level exam. It also shows the percentage of students who qualify for a subsidized lunch and the percentage of graduates who passed at least one college-level test.
The Oakland school board revoked the charter of three high-scoring American Indian schools last year, due to financial improprieties. AIPCHS and its sister schools remain open on appeal.
The list excludes selective schools, such as Stuyvesant in New York City, and schools that attract primarily high achievers, such as BASIS Scottsdale, a charter that became very popular with parents of high achievers. Mathews explains:
We do not include any magnet or charter high school that draws such a high concentration of top students that its average SAT or ACT score exceeds the highest average for any normal-enrollment school in the country. This year, that meant such schools had to have an average SAT score below 2005 or an average ACT score below 29.3 to be included on the list.
The Challenge Index is designed to identify schools that have done the best job in persuading average students to take college-level courses and tests. It does not work with schools that have no, or almost no, average students. We put those schools on our Public Elites list.
