MT Private Investigator

The Private Security Program within the Department of Labor & Industry's Business Standards Division. For applications, renewals, and licensing status, call Professional Licensing Customer Service at (406) 444-6880 or email [email protected]. Scope-of-practice questions go to the Executive Officer at (406) 841-2037 or [email protected]. Mailing address: PO Box 200513, Helena, MT 59620-0513.

The program publishes an Exam Information page but does not post a public blueprint with domain weights. Expect coverage of the Private Security statutes and Administrative Rules, licensing and ID card duties, recordkeeping and address-update obligations, complaint and disciplinary procedure, and the lawful scope of investigative work. Treat any published weighting you see elsewhere as unofficial.

Those figures are not stated on the program pages this guide is built from, so no number is given here rather than an outdated guess. Confirm question count, time limit, passing score, and fee with the program at (406) 444-6880 before you schedule. Exam delivery details can change between rule revisions.

The program's public pages do not state a retake waiting period or an attempt limit, so verify directly with Professional Licensing Customer Service at (406) 444-6880. Note that applications remain valid for one year under normal circumstances, which generally gives you room to complete remaining requirements, including exams, without refiling.

Yes. Private investigators and private investigator trainees must have ID cards. Effective July 1, 2024, the Department no longer issues ID cards to individual licensees; licensed firms create them for staff under Administrative Rules update 24.182.403. Cards must be credit-card sized, durable or laminated, show a clear recent photo, first and last name, license type, license number prefixed 'Department of Labor & Industry License Number', issuance date, employer, supervising private investigator if applicable, and the Department-issued license QR code.

Under HB 276 (2025), all licensees and applicants must give the Department a current mailing address and report any change of address within 30 days. You may consent to electronic service of legal notices by supplying a current email address and updating it within 30 days of any change. Email is the Department's primary communication channel, so keep it active.

Scoring mechanics are not published on the program pages, so confirm with the program. The most common content failures are predictable: confusing the pre-2024 assumption that the Department issues ID cards with the current firm-issued model, missing the 30-day address and email update windows, and not knowing which Administrative Rule governs ID cards (24.182.403) versus uniforms (24.182.407).

Start with statutes and administrative rules, since every other domain depends on them. Then licensing, ID cards, and recordkeeping, because those rules are concrete and heavily dated. Next professional conduct and the complaint process, including service of process under HB 276. Finish with investigative practice and scope of authority, where judgment questions reward knowing the boundaries set in the first three domains.

Use the Licensee Lookup System, described by the program as the primary source for verifying credentials. The Department does not guarantee the accuracy of the listing, and some disciplinary actions may not post immediately because appeals and administrative processes can delay updates. A separate License Verification Request requires the license number and carries no charge. Records before July 1, 1996 require contacting the program.

Contact the complaint line at (406) 841-2091 or [email protected]. Because HB 276 added attestations about participating in the complaint and contested case processes, applicants and licensees should understand the disciplinary path before they apply. Providing false information to the Department is treated as unprofessional conduct under the Licensee Lookup disclaimer.
