To become a private investigator in Missouri, you need to meet several requirements set by the Missouri Division of Professional Registration, specifically managed under the Board of Private Investigator and Private Fire Investigator Examiners. Here are the basic qualifications you’ll need to meet in order to become a licensed PI in Missouri.

  • High School Diploma or Equivalent: You must have a high school diploma or an equivalent (GED).

    • What Disqualifies You from Becoming a PI in Missouri?

    Several factors can disqualify you from becoming a private investigator in Missouri. These disqualifications are mainly related to your legal and criminal background, as well as your professional and personal conduct. Here are the key disqualifiers.

    Criminal Background

  • Felony Convictions: Any felony conviction will disqualify you from obtaining a private investigator license.
  • Crimes of Moral Turpitude: Convictions for crimes involving moral turpitude, which generally include offenses that involve dishonesty, fraud, deceit, or immoral conduct, will disqualify you.
  • Serious Misdemeanors: Certain serious misdemeanor convictions, especially those related to theft, violence, drug offenses, or other crimes that suggest a lack of good moral character, can also be disqualifying.

    • Professional Conduct

  • Revocation of Previous Licenses: If you have had a private investigator license or any professional license revoked in Missouri or any other state, this could disqualify you.
  • Professional Misconduct: Evidence of professional misconduct or unethical behavior in previous employment or professional roles may also disqualify you.

    • Legal and Regulatory Compliance

  • Failure to Disclose: Failing to disclose required information on the application, like past criminal convictions or disciplinary actions, can result in disqualification.
  • Fraudulent Applications: Providing false information or documentation in your application process will lead to disqualification.

    • Other Disqualifiers

  • Inability to Obtain a Surety Bond: If you cannot secure the required surety bond, you may be disqualified from obtaining a license.
  • Lack of Required Experience: Not meeting the minimum experience requirements (two years in a relevant field) can disqualify you.
  • Failure to Pass the Exam: Not passing the Missouri Private Investigator licensing exam will prevent you from becoming licensed.

    • Health and Mental Fitness

    1. Mental Incompetency: If there is evidence of mental incompetency that affects your ability to perform the duties of a private investigator, you may be disqualified.

    Citizenship and Residency

    1. Non-U.S. Citizen Without Legal Residency: If you are not a U.S. citizen or do not have legal residency status, you cannot obtain a PI license in Missouri.

    How to Gain Relevant Private Investigative Experience

    Gaining the necessary experience to become a private investigator in Missouri involves a combination of education, relevant work experience, and practical training. Here are the steps and methods you can use to acquire the experience needed to meet Missouri's requirements.

    Education

    • Post-Secondary Education: While not mandatory, pursuing a degree or coursework in criminal justice, law enforcement, or a related field can be beneficial. These programs often cover investigative techniques, criminal law, and ethics, providing a strong foundation for a career in private investigation. These programs are usually more than satisfactory for meeting the minimum experience requirements.

    Relevant Work Experience

  • Law Enforcement: Serving as a police officer, detective, or in another law enforcement role provides valuable investigative experience. Skills gained in these positions, like interviewing witnesses, gathering evidence, and conducting surveillance, are directly transferable to private investigation work.
  • Military Service: Working in military police or intelligence roles can also provide relevant investigative experience.
  • Security Services: Positions in security, like a security guard or loss prevention specialist, can offer practical experience in monitoring, reporting, and handling security incidents.
  • Investigative Roles: Jobs with investigative duties, like insurance fraud investigator, legal investigator, or claims adjuster, count towards the required experience. These roles involve many of the same skills and tasks as private investigation.

    • Training Programs and Internships

  • Internships: Seek internships or trainee positions with established private investigation agencies. These opportunities allow you to gain hands-on experience under the supervision of experienced investigators.
  • Training Programs: Enroll in professional training programs or courses specifically designed for aspiring private investigators. These programs often cover essential skills like surveillance techniques, report writing, and legal aspects of private investigation.
