NY StateEducation Law '2590-g(12)(b) provides:

Admissions to the Bronx High School of Science, Stuyvesant High School and Brooklyn Technical High School and such similar further special high schools
which may be established shall be solely and exclusively by taking a competitiveobjective and scholastic achievement examination,
which shall be open to each and every child in the city of New York in either the eighth or ninth year of study,
without regard to any school district wherein the child may reside. No candidate may be admitted to a special high school
unless he has successfully achieved a score above the cut-off score for the openings in the school for which he has taken the examination.
The cut-off score shall be determined by arranging the scores of all candidates who took the examination and who then commit themselves to attend the school
in descending order from the highest score and counting down to the score of the first candidate beyond the number of openings available.
