Fifty of the participating teachers responded with written evaluations with 86 percent saying they will use the program again within the next six months. There were 554 students who returned feedback postcards and, of these, 443 felt stamps were of some help in teaching

Stamps Teach currently offers a total of fifteen lesson plans for math, science, social studies and language arts, with more planned."
