Reports from the second and third semesters of the operation of the Chicago Public High School for Metropolitan Studies, covering the year from July 1970 to June 1971, follow up earlier documents reflecting the content and philosophy of this alternative school. A chronology of second semester events opens the second semester report, followed by sections dealing with curriculum, counseling, governance and organization structure, participating organizations, administrative support procedures, staff development, and recommendations for 1971-1972 expansion. Appendix A describes the Summer Workshop which initiated the second semester. The third semester report opens with a statement of the school's philosophy to profit from the continuous and careful analysis of the school's progress and with a description of semester events. Next, the Urban Research Corporation, authors of the report and consultants to the school, list accomplishments, problems, and recommendations as a final statement at the end of their association with the school. Appendices documenting difficult events in the third semester of the school's existence complete the report. (JH)
