High School
Recommended high school courses include geography, business, mathematics, and physical education. Speech, English, and even a foreign language will help to develop communication skills that are needed in dealing with mail carrier customers as well as coworkers and supervisors.
Postsecondary Training
No postsecondary training is required for mail carriers. They typically receive on-the-job training, which usually lasts a few weeks. They often work alongside an experienced carrier to obtain experience.
