I would say to these students: No one can promise you will land a job, not in this or any other field, but I can promise you that teaching is the most exciting, rewarding, and important job you will ever have. It will change your life, and you all have the opportunity to make a difference in the lives of your students.

What would you say to them?

I wrote to the celebrities [who are in “Teachers Rock”], and I hope all our messages make a difference. I have a pressing question that I hoped to have answered for myself by now, but I’m still searching. In less than 2 weeks I’ll be standing in front of 26 20-somethings who are preparing to be teachers. They’ll be taking at least 36 units of education courses over at least 2 years, completing countless hours of student teaching, passing several standardized tests, and expecting to make a positive difference in children’s lives. They’ll also be expecting to get a teaching job and keep it. Many readers of this blog must be in a similar place. What shall we say to these hopeful, idealistic, young people?
