 For many years the School was a part of the education department of the West Side Branch, first on West 57th Street and then, in 1929, at 5 West 63rd Street where a separate portion of the larger building was prepared for the School.By 1935 the educational work of the City Association had increased to a point where a Schools Branch was justified.The direction of this Branch centered in McBurneys' 15 West 63rd Street building and provided for the operation of four, sometimes five, schools.
