John Adams High School was a public high school in Portland, Oregon, United States, managed by Portland Public Schools (PPS). Located at 5700 N.E. 42nd Avenue Portland, Oregon the school opened in 1969. Its curriculum, based on ES-70 and further developed by students and faculty at Harvard Graduate School of Education, had a unique and sometimes controversial approach to secondary education. The school was organized into four different sub-schools, or "houses", each with a multiple-discipline and general education focus. Students were given the choice of selecting elective classes and were also offered the opportunity to gain educational experiences outside of the classroom. As student enrollment fell, the school closed in 1981.
