One exception to this rule was Brooklyn Tech, an academic high school with an emphasis on engineering, which admitted all its students in the 9th grade. Brooklyn Tech and a handful of other specialized public schools drew its students from the entire city. Students were admitted based on the results of an entrance examination administered by Columbia University, the same exam used for Stuyvesant and Bronx Science.
In 7th and 8th grades, J.H.S. 22 had two SPE classes. Enough students left for Brooklyn Tech that the school combined the two classes into one for 9th grade. In the 1966-67 year, this resulted in a class size of 37.
