Montana LMSW Requirements: Hours, Exams & Step-by-Step Guide

Montana’s multi-tiered social‑work licensing system now includes a non‑clinical Licensed Master’s Social Worker (LMSW) level regulated by the Montana Board of Behavioral Health. The pathway is structured around a candidate period, defined supervised work experience, and a national examination, all grounded in statute (Montana Code Annotated, Title 37, Chapter 22) and the Administrative Rules of Montana (ARM).

Below is a step‑by‑step guide focused on the exact hour requirements and board terminology in effect as of 2025.

1. What the LMSW License Is in Montana

Under Montana law, a “master’s‑level social worker, also known as a licensed master’s social worker,” is one of three levels of social work licensure, along with Licensed Baccalaureate Social Worker (LBSW) and Licensed Clinical Social Worker (LCSW).(law.justia.com)

The LMSW is a non‑clinical license. A licensed master’s social worker:

• Must meet the requirements in §37‑22‑308, MCA.(law.justia.com)
• “May engage in social work activities” listed in statute (e.g., assessment, case management, advocacy) but not independent clinical psychotherapy; that level requires LCSW licensure under §37‑22‑301.(law.justia.com)
• May use the initials “LMSW” (licensed master’s social worker) once licensed.(law.justia.com)

2. Education Requirements

To qualify as an LMSW in Montana, an applicant must:

• Hold a master’s degree in social work from a Council on Social Work Education (CSWE)–accredited program or another program approved by the board by rule.(law.justia.com)

(Some board‑approved alternative education/experience routes exist mainly in the clinical‑level statute; if you do not have a CSWE‑accredited MSW, you must show the board that your education and additional experience are equivalent under its rules.(law.justia.com))

3. Mandatory Candidate Stage: LMSW Candidate (SWLM)

Montana requires you to complete supervised work as a candidate before you can be fully licensed as an LMSW.

3.1. Register as a Social Worker Licensure Candidate

Statute requires that an applicant to be a licensed master’s social worker:

• “Must have registered as a social worker licensure candidate… and completed supervised work experience as specified in 37‑22‑313 and board rule.”(law.justia.com)

The Board implements this through the Licensed Master’s Social Worker Candidate (non‑clinical) credential (license type SWLM). The board’s license information page specifies:(boards.bsd.dli.mt.gov)

• You apply online as an LMSW Candidate.
• You must undergo a fingerprint‑based background check through the Montana Department of Justice; results go directly to the Board.
• The candidate license has its own renewal period (Nov. 1–Dec. 31) and fee, but no continuing‑education requirement while you are a candidate.

In practice, you cannot lawfully accrue LMSW‑qualifying supervised hours in Montana without this candidate registration.

4. Supervised Work Experience: Exact Hour Requirements

The detailed hour requirements for LMSW supervised work are set out in ARM 24.219.504 – LCSW, LMSW, and LBSW Supervised Work Experience Requirements.(regulations.justia.com) This is the controlling rule as of June 2025.

4.1. Total Supervised Work Experience Hours

For the LMSW level, the rule states that applicants must complete a minimum of 1,500 total hours of supervised work experience:

• “LMSW applicants must complete a minimum of 1500 total hours of supervised work experience over a period of no less than 18 months.” (Paraphrasing ARM 24.219.504(3))(regulations.justia.com)

Key points:

• These are 1,500 total hours of supervised social work practice, not 1,500 direct plus 1,500 indirect (that 1,500 + 1,500 structure exists for LCSW clinical hours, not for LMSW).(law.justia.com)
• The minimum time frame is 18 months. You cannot compress the hours into less time and still meet the rule.
• For LMSW (unlike LCSW), the rule does not specify a required minimum of “direct client contact” hours; instead, it focuses on your total supervised work and a specific number of supervision hours, some of which must directly involve your target client populations.

4.2. Required Supervision Hours Within the 1,500

Within those 1,500 total supervised hours, the Board requires a specific amount and type of supervision:

• At least 75 hours must be individual or group supervision by a qualified supervisor (as defined in ARM 24.219.421).
• Of those 75 supervision hours, at least 25 hours must occur with the client populations that will be served by the LMSW candidate (for example, children, adolescents, adults, or substance‑use populations).(regulations.justia.com)

The rule also imposes an ongoing supervision ratio:

• Supervisors “must provide at least two hours of supervision for LCSW, LMSW, and LBSW candidates for every 160 hours of social work.” (Paraphrasing ARM 24.219.504(4))(regulations.justia.com)

Practically, this means:

• Every 160 hours of your work as a candidate must be accompanied by 2 hours of documented supervision, which can be counted toward the 75‑hour supervision minimum.

4.3. Time Limit on When Hours May Be Earned

For candidates who are not already actively licensed in another jurisdiction, the Board limits how old your supervised hours can be:

• “Supervised work experience hours earned by LMSW and LBSW applicants who are not currently actively licensed in another jurisdiction must have been earned within five years of the date of application.” (Paraphrasing ARM 24.219.504(6))(regulations.justia.com)

In other words, if you are applying for an LMSW in Montana and you are not an active social‑work licensee elsewhere, your 1,500 supervised hours must fall within the five‑year window immediately preceding your Montana application.

5. Supervisor Qualifications and Board Terminology

The Board’s general rule on supervisors is ARM 24.219.421 – Supervisor Qualifications, which applies to social‑work candidates including LMSW candidates.(regulations.justia.com)

5.1. Who May Supervise an LMSW Candidate?

The rule specifies that:

• “LMSW candidate supervisors must be licensed as an LCSW or LMSW.” (ARM 24.219.421(4), paraphrased)(regulations.justia.com)

So your supervisor must:

1. Hold an active license in good standing in the jurisdiction where supervision occurs; and
2. Be licensed as either an LCSW or LMSW.

5.2. Additional Supervisor Requirements

All supervisors (including those for LMSW candidates) must also:(regulations.justia.com)

• Have been licensed in their discipline for at least three years (excluding any candidate period), or
• Complete board‑approved supervision training (at least one graduate semester credit in supervision or 20 hours of Board‑approved training in supervision).

Furthermore, the Board requires that a supervisor:

• Have experience and expertise with the candidate’s client population (e.g., children, adolescents, adults, substance‑use populations).
• Have experience in the methods of practice the candidate is using (individual, group, family, crisis, brief interventions, etc.).(regulations.justia.com)

This is why ARM 24.219.504 explicitly references “client populations that will be served by the LMSW candidate” when it requires that 25 of the 75 supervision hours occur with those populations.

6. Examination Requirement

After your supervised work experience as a social worker candidate is complete, §37‑22‑308 requires that you:(law.justia.com)

1. Pass an examination prescribed by the Board (by rule, this is the ASWB Master’s examination). The Board’s LMSW and LMSW Candidate license information confirms that Montana accepts ASWB Master’s‑level scores.(boards.bsd.dli.mt.gov)
2. Submit a completed application for licensure and an application fee.
3. Undergo a fingerprint‑based criminal background check as a prerequisite to licensure, pursuant to §37‑1‑307, MCA; this is reiterated on the Board’s LMSW and LMSW Candidate pages.(law.justia.com)

Note that under current statute, the exam comes after you have completed your supervised experience as a candidate, not before.(law.justia.com)

7. Legacy Clause (Now Expired) vs. Standard Path

During 2023–2024, Montana had a temporary “Legacy Clause” that allowed some experienced social workers to obtain LBSW or LMSW licensure without supervised‑hours documentation or an exam if they had at least 4,000 aggregate hours of practice in a specified historical window and met education requirements.(socialworkdegree.net)

• NASW Montana notes that this Legacy Clause sunset on December 31, 2024.(naswmt.socialworkers.org)

As of 2025, new applicants must follow the standard path:

1. Education (MSW).
2. Registration as an LMSW candidate (SWLM) plus background check.
3. Completion of 1,500 hours of supervised work experience over at least 18 months, including 75 hours of supervision (25 with your client populations).(regulations.justia.com)
4. Passing the ASWB Master’s exam.(law.justia.com)
5. Submission of the licensure application and fee, and successful review by the Board.
