Park rangers provide many levels of safety, assistance and nature programs to hikers, campers and wildlife. Meeting the requirements to become a park ranger requires testing by the civil government. There are three tests an applicant takes in progression, which means if one test is failed, you will not be allowed to move on to the next exam. Throughout the process, there are also interviews that take place. These interviews are graded or scored and count as part of the testing.

Research the requirements of the ranger job you want to apply for. Each public park, state park or national forest requires different duties and skills.

Study for the examinations. The government position should list which tests are required prior to employment. For a park ranger position, the tests will include a multiple choice exam, a physical ability test and testing of overall qualifications.

Complete and pass the multiple choice test. This test checks for medical criteria and EMT (emergency medical technician) knowledge. You will also be tested for comprehension and English language skills. It is at this point you will be completing your park ranger training.

Complete and pass the physical ability test. This test will "measure agility, balance, strength and endurance."

Complete and pass the evaluation of overall qualifications. In this test you and your qualifications will be questioned and reviewed by a team of peers in your industry. The team will review your application, background check and the completed multiple choice test.

Complete and pass, if required, the psychological examination. Many positions with the government that deal with the public or carrying of firearms will require a psychological evaluation.
