About this exam

The Ohio Private Investigator credential is issued and regulated by Private Investigator Security Guard Services (PISGS), a component of Ohio Homeland Security. PISGS licenses and regulates the private investigation and security guard services industry throughout Ohio, and it currently oversees more than 800 providers with nearly 24,000 registered employees. Ohio law requires people or companies offering security or investigation services to obtain a license, licensed companies must register their employees, and providing investigation or security services without a license is a crime. PISGS verifies that a company is insured, that it is operated by a qualifying agent with appropriate experience, and that employees undergo criminal background checks; registered employees are also monitored through the state's Rapback system, which notifies PISGS if a guard or investigator is arrested. Candidates typically pursue the credential as a qualifying agent or as a registered employee of a licensed company, and exam content tracks the PISGS program areas: licensing law and administrative rules, investigative technique, evidence handling, surveillance, legal and ethical limits, reporting, firearm-bearer requirements, and business/insurance obligations. Preparation should center on the Ohio Revised Code and Administrative Code Title 4501:5, PISGS fee and renewal notices, the free online training PISGS offers for investigators, guards, and qualifying agents, and the firearm-bearer endorsement documentation.

What you'll study

Common questions

About OH Private Investigator preparation

Do I need a license to work as a private investigator in Ohio?

Yes. Ohio law requires people or companies offering security or investigation services to obtain a license, and licensed companies must also register their employees. PISGS states plainly that providing investigation or security services without a license is a crime. Verify any prospective employer through the PISGS licensed provider search before accepting work.

What does the exam actually test?

Expect coverage of Ohio licensing law and PISGS administrative rules, investigative technique and case management, evidence collection and chain of custody, surveillance and observation, privacy/trespass/recording limits, report writing, firearm-bearer endorsement requirements, and business obligations such as insurance and registration. Weight the licensing-law and legal-constraints material heavily because those rules drive the rest.

How long is the exam, how many questions, and what score passes?

PISGS does not publish question count, time limit, or passing score in the program material summarized here, so treat any specific figure you see elsewhere as unverified. Confirm current test specifications directly with PISGS at (614) 466-4130 before you schedule, and build your study plan around content coverage rather than a target question count.

What happens if I fail - can I retake it?

Retake policy, waiting periods, and any additional fees are not stated in the PISGS material summarized here. Call PISGS at (614) 466-4130 or review the PISGS fees page for the current per-transaction charges before assuming a retake is automatic. Plan to pass on the first attempt.

What are the qualifying agent requirements?

PISGS verifies that a company is insured, operated by a qualifying agent with appropriate experience, and that its employees undergo criminal background checks. The qualifying agent is the individual through whom the company is licensed, so both the company license and the qualifying agent must be renewed together when the license expires.

When do licenses and qualifying agent registrations renew?

For providers whose licenses expire in 2026, PISGS states that the license and the qualifying agent or agents must be renewed prior to March 1, 2026. Because renewal cycles are date-driven, always check your own expiration date in the PISGS online services portal rather than assuming a calendar year.

What is the firearm-bearer endorsement?

It is a separate endorsement for qualifying agents and registered employees who wish to carry a firearm while working. PISGS publishes the required training and documentation on its firearm-bearer endorsement page. Do not assume a private investigator license alone authorizes armed work - the endorsement is an additional requirement.

Is there free official training I can use to prepare?

Yes. PISGS offers free online training for Ohio security guards, private investigators, qualifying agents, and cannabis employees, plus an informational seminar. That material mirrors the regulator's own framing of the rules, so pair it with a careful read of the licensing statutes and administrative rules rather than relying on it alone.

What are the most common ways candidates lose points?

Three repeat offenders: studying generic investigation practice instead of Ohio-specific licensing rules; confusing company licensing with employee registration; and ignoring legal constraints such as privacy, trespass, and recording limits. Also memorize who does what - PISGS verifies insurance, qualifying agent experience, and background checks, and Rapback monitors arrests.

How should I sequence my studying?

Start with licensing law and PISGS rules, since every other domain depends on knowing who may investigate and under what authority. Then move to legal and ethical constraints, then investigative technique and surveillance, then evidence handling and report writing. Finish with firearm-bearer requirements and business, insurance, and registration obligations.
