How to Apply to Be a Civil War Battlefield Park Ranger
by Christopher Raines
The U.S. National Park Service preserves the sites of important Civil War battles to tell the story of a divisive period in American history. As a park ranger at one of these battlefields, you wear the hat of historian, teacher, and tour guide to students and other visitors. You also enforce rules and regulations that seek to safeguard the cleanliness and artifacts of these solemn places and ensure they are treated with respect.
Know Civil War History?
Your application should highlight teaching and research, especially in the Civil War or the battlefield where you want to work. Build your knowledge of and experience with battlefields such as Gettysburg by participating in summer internships. If you rely on your academic background, a bachelor's degree in American history with courses or a concentration in the Civil War could bolster your resume. Park rangers also present Civil War lectures in the the Department of Interior's Park Ranger speakers' series, so some public speaking classes or experience, along with knowledge of the Civil War, could help.
Able to Enforce Rules?
Battlefield park rangers, especially those employed full time, enforce rules and regulations against alcohol use on park grounds, hunting for relics, and taking artifacts and other cultural and natural resources from the battlefields, so rangers generally must obtain some enforcement experience. Law enforcement officers in the Park Service must pass drug tests, physical fitness tests, which include a 1.5 mile run and an agility run, and criminal background and security checks. Your physical endurance will also come in handy because leading tours of battlefields requires constant walking.
Can You Drive Safely?
Present any records, such as your past and present driver's licenses, that show you have held and currently hold a license. You will likely have to submit your driving record and a completed GSA Form 3607, which you can download from the U.S. General Services Administration website. Form 3607 inquires about your accidents, tickets, convictions for driving while impaired with alcohol or other substances and any instances when you have used a government vehicle without authorization.
Applying for Federal Jobs
To apply for federal government jobs, create an account at the USA Jobs website. During the process, enter information about yourself and fashion a resume. Type in "park ranger" and follow the specific instructions for applying for particular park ranger positions. Depending on the job, you might need to complete a questionnaire and furnish your college transcripts. To obtain a veteran's preference in federal jobs, submit a copy of a form showing your honorable discharge from the military discharge letter, known as a DD-214; an application for a veteran's preference, called an SF-15; and Veterans Administration preference letter. Go to the National Archives website to get your military discharge record and the U.S. Office of Personnel Management site to download the veteran's preference application. Some jobs may be available only to applicants who have lost jobs in the federal government.
