Teaching: The Profession That Creates All Other Professions

To teach the 50.1 million students that attend public school in 2015, schools will employ about 3.1 million teachers. The resulting ratio of students to teachers will be 16 to 1—however, the number of students in each classroom will be far from even. Many teachers can expect to teach upwards of 25 students, all while spending an average of around $500 of their own money on school supplies.
