Copy your undergraduate diploma and state or territorial license. Edit and update your resume. Submit to the Human Resources Regional Service Center. Also provide a cover letter summarizing why you would be a good fit in Department of Defense schools and stating any unique qualities that you have. State places in which you would be willing to work.
Review your materials one final time before submission. If you do not hear back by letter or email confirming your application, follow up with the Department of Defense Education Activity within two to three weeks of submitting all of your documentation.
Read up on interviewing skills. If called for an interview (remember: not all applicants are summoned for interviews), bring copies of your resume and portfolio, if required. (A portfolio might be useful for arts teaching positions, for example. This document shows off your work.) When offered the job, arrange your travel accordingly. Review the policy binder of your new employer. Learn about the region of America or the country you will be living in, if it is not your home state.
