Types of Duties
Investigation officers conduct inquiries to discover who committed crimes and to gather evidence to prosecute and convict suspects. Officers interview suspects and witnesses, examine evidence and conduct research through computer databases and other sources. Officers write reports based on their findings and are often called upon to appear in court to explain the results of their investigations. While performing their work, officers must follow laws that protect the rights of suspects, such as obtaining warrants before conducting searches.
Most law enforcement agencies require investigation officers to meet minimum physical fitness standards to work in the field. Undergoing and passing criminal background checks and psychological tests are typically necessary as well. Some law enforcement agencies also require prospective criminal investigators to take the United States civil service examination. Investigation officers must typically carry a handgun and are required to maintain a license for their weapons. To perform their investigations and file reports, officers need the ability to use database, word processing, e-mail and photo imaging software, explains the Occupational Information Network.
Education requirements for investigation officers vary from employer to employer, but a high school diploma or GED is generally necessary. Approximately 62 percent of officers have a four-year bachelor's degree, reports the Occupational Information Network. Law enforcement agencies usually provide extensive training for new hires. These courses usually last 12 to 14 weeks, explains the U.S. Bureau of Labor Statistics. New officers are typically given basic assignments and may assist more accomplished professionals during their first one to two years of employment.
