Private detectives and investigators work in many environments, depending on the case. Some spend more time in offices, researching cases on computers and making phone calls. Others spend more time in the field, conducting interviews or performing surveillance.

Although investigators often work alone, some work with others while conducting surveillance or carrying out large, complicated assignments.
Work Schedules
Private detectives and investigators often work irregular hours because they conduct surveillance and contact people outside of normal work hours. They may work early mornings, evenings, weekends, and holidays.
Private detectives and investigators typically need several years of work experience and a high school diploma. In addition, the vast majority of states require private detectives and investigators to have a license.
Education
Education requirements vary greatly with the job, but most jobs require a high school diploma. Some, though, may require a 2- or 4-year degree in a field such as criminal justice.
Training
Most private detectives and investigators learn through on-the-job training, typically lasting between several months and a year.
Although new investigators must learn how to gather information, additional training depends on the type of firm that hires them. For example, investigators may learn to conduct remote surveillance, reconstruct accident scenes, or investigate insurance fraud. Corporate investigators hired by large companies may receive formal training in business practices, management structure, and various finance-related topics.
Work Experience in a Related Occupation
Private detectives and investigators must typically have previous work experience, usually in law enforcement, the military, or federal intelligence. Those in such jobs, who are frequently able to retire after 20 or 25 years of service, may become private detectives or investigators in a second career.
Other private detectives and investigators may have previously worked as bill and account collectors, claims adjusters, paralegals, or process servers.

Candidates may also obtain certification, although it is not required for employment. Still, becoming certified through professional organizations can demonstrate competence and may help candidates advance in their careers.
For investigators who specialize in negligence or criminal defense investigation, the National Association of Legal Investigators offers the Certified Legal Investigator certification. For other investigators, ASIS International offers the Professional Certified Investigator certification.
