This handbook is for people in the field of English language teaching who are looking for practical ways to be both committed followers of Jesus and ethical TESOL professionals. What do such teachers actually do in the classroom? What materials do they use? How do they relate to their students and colleagues in and outside the classroom? How can they treat students as whole people, with spiritual and religious identities? How can they set a high bar for ethical teaching? Professional Guidelines for Christian English Teachers has grown out of Kitty Purgason’s experience as a Christian seeking to follow the Great Commandment and the Great Commission, as a practitioner with a deep concern for excellence and integrity, and as a teacher trainer with experience in many parts of the world.
