I am writing to confirm my acceptance of your employment offer on April 20 and to tell you how delighted I am to be joining XYZ Corporation in Chicago. The acceptance letter is a simple and pleasant letter to write.In the first paragraph, thank the company for the offer and directly accept the position. I'm a first year art teacher trying to move to Chicago for the next school year and I've been doing job applications like crazy. Note that the letter clearly states important contract terms like offered position, salary, benefits and special considerations like flex time. Throughout the letter, be specific about how you will carry out research, teaching, and service at the hiring institution. Each spring, AUSL principals observe residents in the classroom and select new teachers for their schools. Education is a lifelong process, but the opportunity to choose a college or university doesn't come around often. So it's not a letter.
