I believe that achievement cannot be measured by one test score and that learning is a process, not a product. Most important, I do not view students and parents as "customers," as I am a teacher, not a salesperson. My work in the classroom is not designed to sell anything. It is to prepare my students to think critically, especially about how messages are being communicated and with what evidence. With that in mind, I'd like to clarify some of Handy's points so citizens may make a well-informed decision about DeVos's nomination as U.S. secretary of education.
