Various aspects of public education in Portland, Oregon, since 1950, are reviewed in this document. Past enrollment trends, the current decline in enrollment, and the demographic distribution of that decline are described. Possibilities for future enrollment are examined based upon assumptions about future fertility and migration trends. In addition, information is offered about the number and physical condition of public schools in the district, including a list of their respective construction dates. Cooperative programs between the city and the school district are also described. Financial considerations are discussed in an examination of the school district budget and the problem of rising costs. A reorganization plan, drawn up by the school board in 1970, is outlined. The state of implementation of the plan, which calls for strengthening educational policy in the upper grades and the shift to middle schools for improving services to adolescent students, is reviewed.
