We've learned from teachers that they overwhelmingly chose their profession in order to make a difference in children's lives. Eighty-five percent say this according to our survey of more than 20,000 PreK-12 teachers, Primary Sources: America's Teachers on Teaching in an Era of Change. Two-thirds also agree they are teachers to be part of those "aha" moments when things just click for students. These sentiments make you feel great about who is leading our nation's classrooms. And as one teacher inspired us with a quote, we want to share it with you as well. For even more inspiring quotes or more about teachers' views on a range of topics facing educators today, check out the full report.
