Education graduates who plan to become a teacher or an administrator (e.g., principal or superintendent) in a public school district will need to follow the proper procedure to become licensed before they can begin working. Each US state has its own set of licensing or certification requirements, so it's best to check with your particular state before embarking on a path to become an educator or administrator. In general though, educators and administrators must earn an accredited degree, have professional experience, and pass at least one competency exam.
Holy cow, the universities make a boatload off of textbooks! Using one book for a semester (even with selling it back) can cost $100 plus! Many companies like Amazon sell textbooks cheaper than at universities and offer gift cards at a decent rate to sell them back. I had a great experience with the buyback program…much better than selling a book back for next to nothing at the school store!
