The programs of four full-time and two part-time senior centers in the Chicago area are discussed and evaluated. The average number of participants in the centers' programs per month is 2,298. Each full-time center provides the following basic program of direct services: Assistance in Income Maintenance; Counseling; Education, Employment and Related Opportunities; Information and Referral; Service and Community Participation Opportunities; Supportive and Preventive Maintenance Programming; and Community Education in Aging. In addition to these core services, each center developed one "special emphasis" pilot project in 1968. An evaluation is made of the programs of each center. Community resources, administration, and budgetary problems are discussed. It is felt that the direction of the program as a whole needs reaffirmation of its own working definition; administrative reforms are needed to streamline and simplify the mechanics of operation and to more closely relate the field operation to general commission goals and activities; and the feasibility of sustaining the effort with diminishing funding and resources must be studied. Goals for 1969 are listed. (Not available in hard copy due to marginal legibility of original document.) (DB)
