A report is given of a study in which a valid and reliable instrument was developed to measure levels of teacher motivation and teachers' degree of satisfaction with their principal's administration of the school. Based upon responses from educators who validated the instrument, certain factors were seen as important in determining teacher motivation. Teachers must see teaching as worthwhile and stimulating, and they must feel a sense of involvement in decision making and also independence in their classroom teaching. The teacher must have a feeling of affiliation with others. There must also be a sound reward system that offers not only extrinsic rewards but also a sense of success and recognition. Teachers need the opportunity for personal growth and require accurate and sensitive feedback from their principals. A feeling of physical and emotional safety in the organizational structure of the school is important to teachers. Teachers require confidence in the principal, and also require the principal to provide support and an adequate supply of resources for instruction. (JD)
