How to Become a Fish and Game Warden with the Illinois Department of
Natural Resources

Fish and game wardens in Illinois are called Conservation Police Officers. They have full police authority to enforce all the laws of the state of Illinois, although their specific focus is on natural resource protection and recreational safety. Other duties include speaking and interacting with the public at various events; assisting with hunting, boating, and snowmobiling safety programs; and assisting other law enforcement agencies as requested.

Meeting the Degree and Experience Requirements – Conservation Police Officers enforce Illinois firearms and FOID laws, are members of the Illinois Terrorism Task Force, and are important contributors to Homeland Security efforts, drug prevention operations, and disaster relief and search and rescue operations. As such, education and experience qualifications are quite stringent:

New applicants must have either:

  • An Associate’s degree plus 3 years of experience as a police officer


  • A 4-year Bachelor’s degree

The education requirements may be waived if one of these conditions has been met:

  • Honorable discharge and awarded a service medal
  • Active member of the Illinois National Guard or a reservist in the US Armed Forces and awarded a service medal as a result of honorable service while deployed on active duty

How to Apply – Applicants must complete the State of Illinois CMS (Central Management Services) Employment Application for the position of Conservation Police Officer Trainee. Applicants must take an examination for the position of CPO Trainee which tests:

  • Observation and memory
  • Public relations
  • Writing skills
  • Reading comprehension

The Department of Central Management Services will notify applicants regarding the examination date.

Testing and Evaluation – Eligible applicants are then invited to participate in a POWER (Peace Officer Wellness Evaluation Report) test, which assesses:

  • Aerobic capacity through a 1.5-mile run
  • Strength using bench press weights
  • Muscular endurance as determined by the quantity of sit-ups completed in one minute
  • Flexibility measured by a sit and reach test

Applicants must pass all four tests to continue in the process.

If applicants pass the POWER test, they must complete a swim test which involves

  • Swimming 300 yards using any stroke recognized by the American Red Cross
  • Treading water for 10 minutes
  • Retrieving a 5-lb weight from at least 10 feet of water

This is followed by an oral interview. A positive interview is followed by a thorough background investigation.

Conservation Police Officer Trainee Program – If the outcomes of the interview and background investigation are positive, the candidate is offered the position of Conservation Police Officer Trainee (CPOT), contingent upon a successful medical examination and psychological assessment. New hires are considered Conservation Police Officer Trainees for a minimum of one year.

During the first year of training, the CPOT attends 24 weeks of training in two different programs.

  • 12 weeks of the 480-Hour Basic Law Enforcement Course, which covers basic peace officer topics such as human behavior, patrol techniques, and police proficiency skills
  • 12 weeks of Basic Conservation Police training, which includes 480 hours of training topics that include wildlife enforcement, watercraft safety, state park and site regulations, and endangered species protection

Upon completion of these two training courses, CPOTs receive five months of on-the-job training by working with veteran field officers in a rotation of various field locations. A Conservation Police Officer is considered a “trainee” for at least 12 months, and then undergoes four months of probation before being certified as a Conservation Police Officer.
