The St. Johns (school) District was annexed on July 7, 1915, and the James John High School was added at this time. On the suggestion of superintendent Lewis H. Alderman, high school dances were allowed by the school board beginning in 1915, with the stipulation that "the parents of a majority of the students attend." Portable classrooms were used, especially in 1919, with 60 portables added. By this time, there were evening schools taught at Benson High School, Girls' Polytechnic (later merged with Benson), Commerce, Jefferson High School, Ladd, and Lincoln High School. A new administration building opened at 7th and Clackamas in the Lloyd District.
