Major differences between nonprofit and for profit organizations can be found from the measurement of institutional effectiveness. An objective and thorough per-formance indicator system is needed to accurately measure performance. Thus the purpose of this research is to identify which proper performance indicators are appli-cable to educational and cultural foundations. Research was conducted through mailed questionnaires and indepth interveiws, seeking the subjective opinions of the executives in these foundations. Central to this study are the foundation executives' opinions, rath-er than those of outside academics or government bureaucrats. This study concluded that all the indicators identified by the foundation exectives can be classified into three major categories: 1. the overall management of the-foundation: including organizations、employees、operations、finance, and the rela-tionship with employees and participating volunteers, and society's recognition of the foundation. As to the individual indicators, the three most valued indicators are: 1. the quality of the service the foundation provides; 2. whether the resources are allocated correctly; and 3. the foundation's contribution to society. Moreover, the three least valued indicators are: 1. the historical duration of the foundation; 2. the growth in the number of its empolyees; and 3. the total membership in the foundation. Basically, the performance indicator system should be hierachical. The conclu-sions of this research are only meaningful at the first and the second levels. The future research could try to search for lower levels' indicators and the relative weights of all indicators at all levels. And the consolidation of the authorities', scholars', and execu-tives' indicator rankings will make the perfomance indicator system more effective.
