The maximum college readiness index value is 100.0, which means that every 12th-grade student during the 2009-2010 academic year in a particular school took and passed at least one AP or IB test before or during their senior year.
To summarize, in order to be numerically ranked, a high school had to pass Steps 1 and 2 and have a college readiness index at or above the median benchmark.
In total, 84 New York City high schools passed Steps 1 and 2, earning either a numerical ranking or honorable mention status. A high school's position in the numerical rankings, or whether they were awarded honorable mention status, was dependent on how high they scored in all three steps of the rankings methodology.
• Numeric rankings: Schools with highest unrounded college readiness index values were numerically ranked from No. 1 to No. 52.
There were 2 high schools that achieved the maximum 100.0 college readiness index. To avoid having ties in the numerical rankings, the primary tiebreaker, which measures the absolute level of success in passing AP or IB tests, was the unrounded quality-adjusted exams per test taker (the number of exams that received passing scores divided by the number of students who took and passed at least one exam).
If necessary, a second tiebreaker used was exams per test taker, which was the average number of AP and/or IB exams passed per test taker (the total exams taken divided by the number of test takers).
• Honorable mention: An additional 32 New York City high schools that passed the first two steps in the methodology were awarded honorable mention status and are listed alphabetically. A school with honorable mention status either does not offer any AP or IB courses, or its college readiness index was less than the median of 16.3 needed to be ranked numerically.
