LMSW to LCSW in New York

The LMSW Is a Full License

The Licensed Master Social Worker (LMSW) is a full practice license under Education Law Article 154, granted with no experience requirement (Educ. Law 7704(1)(c)). It does not expire. New York has roughly 37,500 active LMSWs, and many hold it as a permanent, standalone credential without ever pursuing the LCSW. Holding an LMSW commits you to nothing.

The clinical path only opens once you begin supervised experience in diagnosis, psychotherapy, and assessment-based treatment plans, inside an acceptable setting, under a supervisor eligible to sign off on that specific work (8 NYCRR 74.3(a); 74.6(c)(2)). Nothing you do as an LMSW before that point, whatever it looks like day to day, counts toward the 2,000 client contact hours. An LMSW who spends two years in case management before deciding to pursue LCSW starts the clock the day the clinical supervised experience begins, not the day the LMSW license was issued.

The 36 to 72 Month Continuous Period

The requirement itself: three years of full-time supervised clinical social work experience, or the part-time equivalent, in diagnosis, psychotherapy, and assessment-based treatment plans, with not less than 2,000 client contact hours, over a continuous period of not less than 36 months and not more than 72 months (Educ. Law 7704(2)(c); 8 NYCRR 74.3(a)). No weekly hour cap is stated, and the law does not define a direct/indirect split beyond the 2,000-hour client-contact floor.

"Continuous" means the 36-to-72-month window is measured from your start date, not from your hour count. Consider three paces against the same 2,000-hour target. An LMSW logging 20 client contact hours a week reaches 2,000 hours in about 100 weeks, roughly 23 months, well under the 36-month floor: the hour count is not what determines readiness here, the calendar is. An LMSW logging 8 hours a week reaches 2,000 hours in about 250 weeks, close to 58 months, comfortably inside the 72-month ceiling. An LMSW logging only 5 hours a week reaches 2,000 hours in about 400 weeks, more than 92 months, which is past the 72-month ceiling entirely.

Filing the Supervision Plan

You may submit a plan for your supervised experience to the Office of the Professions for review and approval (8 NYCRR 74.6(b)). The submission includes proof that the setting is one of the seven acceptable categories, a copy of the supervisor's license, the supervision plan itself, and, if a third party supervises the work, an affirmation that the setting is authorized.

An eligible supervisor under this plan is an LCSW licensed in New York or an equivalent the Department accepts, a psychologist the Department determines is qualified in psychotherapy, or a physician who is a diplomate in psychiatry of the American Board of Psychiatry and Neurology or has equivalent training (8 NYCRR 74.6(c)(2)). Full detail on supervisor eligibility and the supervision hours themselves lives in New York LCSW supervision requirements.

No Private Practice on the Way to LCSW

An LMSW/LCSW limited permit cannot be issued for a private practice owned or operated by the applicant (8 NYCRR 74.4(a)(2), (b)(2)). Separately, an LMSW may not establish a private practice to provide clinical social work services at all. That door opens only once the LCSW is in hand. Whatever setting carries your supervised experience has to be one of the seven categories in 8 NYCRR 74.6(a)(1): a professional service corporation, LLP, or PLLC authorized for the work; a sole proprietorship owned by a licensee; a professional partnership of such licensees; a program operated, regulated, funded, or approved by a state agency such as OMH or a local social services district; an entity holding a 6503-a or 6503-b waiver; a federally authorized program; or another entity otherwise exempt or authorized.

Two Hours a Month Is Not the LCSW Requirement

A separate rule sits next to the LCSW pipeline and is easy to confuse with it. An LMSW who provides clinical social work services but is not counting that work toward LCSW needs only at least two hours per month of in-person individual or group clinical supervision (8 NYCRR 74.6(d)).

That two-hours-a-month figure has nothing to do with the LCSW track's 100-hour supervision total, distributed over the full 36 to 72 months (8 NYCRR 74.6(c)(1)(v)). One is an ongoing-practice minimum for LMSWs who are not pursuing LCSW; the other is the licensure pipeline. Do not average the two rules together, and do not assume time logged under 74.6(d) advances an LCSW application, because it does not.

The 12-Month Limited Permit

An LMSW/LCSW limited permit is available to someone who has met every requirement for LCSW except passing the exam. It is valid for not more than 12 months and is explicitly not renewable (Educ. Law 7705(1); 8 NYCRR 74.4(a)(4), (b)(4)).

If the exam is not passed inside that 12-month window, there is no extension mechanism for this permit. The applicant has to reapply for a new limited permit from the start. Confirm your exam date is well inside the 12 months before applying for the permit at all.

A Different Exam: ASWB Masters to ASWB Clinical

The LMSW exam is the ASWB Masters examination. LCSW is a separate exam, referred to on the application and checklist pages as the ASWB Clinical examination, though the statute itself only says the applicant must "pass an examination satisfactory to the board." It is a different exam from the one you sat for as an LMSW.

Form 4B: One Cumulative Form Per Supervisor

On the LCSW track, you and your supervisor keep a psychotherapy log of your practice and supervision hours, which NYSED says should be completed weekly; the supervisor retains every page in case the State Board requests clarification. The experience itself is verified through Form 4B (Certification of Experience for Licensed Clinical Social Worker), Rev. 10/24, a two-page fillable form completed by the supervisor and returned by the supervisor directly to the Office of the Professions. "The Office of the Professions will not accept this form if submitted by the applicant." If the supervisor is deceased, a licensed professional colleague may submit it instead.

One Form 4B covers one supervisor. If your 36-to-72-month period spans two or three supervisors, expect two or three separate forms. The applicant completes Section I and sends it, along with Appendix A, to each supervisor.

Because Form 4B is filed from the supervisor's own records, not yours, keep your own per-supervisor totals and dates from day one. That is the only way to check what a supervisor attests to against what you actually logged, well before the form is due.

LCSW-R Is Not a Further Step

Once you hold the LCSW, there is no R step to plan for. The "R" designation some LCSWs carry is a legacy credential, discontinued for new applicants since January 1, 2023. See what LCSW-R means for the full history.

These are common errors that delay an LCSW application, every one of them avoidable with a clear record from the first day of supervised experience.
