This paper reviews the process employed in Pennsylvania to develop, refine, select, and implement educational indicators at the state level as part of a state testing program. The indicators are used to provide meaningful comparative information for analysis and planning, to encourage school employees to make productive curricular or organizational changes, and to provide predicted scores for selected cognitive and affective student measures. Means by which the indicator data are reported to school districts are presented, and whether the indicator data were used at the local level is investigated. The selection and refinement of the indicators has taken place over an 18-year period. Currently, over 60 indicators are in use within the state program. Consideration is given to the alteration or replacement of the indicators for use within a national indicator system. Tabulated data and a descriptive tabular listing of indicator condition variables are appended. (TJH)
