A NYTimes overview of the test and experiences in 1998.
…The Stuyvesant test is officially called the ”Examination for the Specialized Science High Schools” — Stuyvesant, the Bronx High School of Science and Brooklyn Technical High School. The same test is given for admission to all three, and students simply list their first, second and third choice. Since a majority of students list Stuyvesant first — 11,397 out of 18,524 eighth graders who took the most recent test — the cutoff for admission to Stuyvesant is higher.
