Strategic Planning for Community Net Zero Energy
The Putney School Mission Mission Statement Adopted June 8, 1997 The Putney School stands for a way of life. Putney is committed to developing each student's full intellectual, artistic and physical potential. Putney students are encouraged to challenge themselves intellectually, to pursue rigorous learning for its own sake, to actively participate in and appreciate the arts, to contribute meaningfully to the work program that sustains the school community and the farm on which it is located, to engage in vigorous athletics, and to develop a social consciousness and world view that will provide the foundation for life-long moral and intellectual growth.
