The results of this test also appear to be gender biased, as girls tend to score significantly higher on state exams and receive better grades, but score lower than boys on the SHSAT. (Girls were only admitted to Stuyvesant and Brooklyn Tech in 1969-1970.) The test is quirky in other ways and is scored to give extra points to students who do exceptionally well on the ELA or the math section – rather than those students who score well on both subjects.
