What is a case manager?

What does a case manager do?

There is no one job description, and that is a fact about the title rather than a dodge. Here is the opening line of what each of the 12 occupations does, in O*NET's words.

• Social and Community Service Managers — Plan, direct, or coordinate the activities of a social service program or community outreach organization.
• Clinical and Counseling Psychologists — Assess, diagnose, and treat mental and emotional disorders of individuals through observation, interview, and psychological tests.
• Substance Abuse and Behavioral Disorder Counselors — Counsel and advise individuals with alcohol, tobacco, drug, or other problems, such as gambling and eating disorders.
• Mental Health Counselors — Counsel and advise individuals and groups to promote optimum mental and emotional health, with an emphasis on prevention.
• Counselors, All Other — All counselors not listed separately.
• Child, Family, and School Social Workers — Provide social services and assistance to improve the social and psychological functioning of children and their families and to maximize the family well-being and the academic functioning of children.
• Healthcare Social Workers — Provide individuals, families, and groups with the psychosocial support needed to cope with chronic, acute, or terminal illnesses.
• Mental Health and Substance Abuse Social Workers — Assess and treat individuals with mental, emotional, or substance abuse problems, including abuse of alcohol, tobacco, and/or other drugs.
• Social Workers, All Other — All social workers not listed separately.
• Community and Social Service Specialists, All Other — All community and social service specialists not listed separately.
• Patient Representatives — Assist patients in obtaining services, understanding policies and making health care decisions.
• Eligibility Interviewers, Government Programs — Determine eligibility of persons applying to receive assistance from government programs and agency resources, such as welfare, unemployment benefits, social security, and public housing.

One of these manages programmes and staff. Several carry a caseload of clients in counselling or social work. One represents patients inside a health system. One determines eligibility for government programmes. They share a job title and not much else, so “what does a case manager do” has 12 answers and the posting decides which applies.

A second O*NET table, Sample of Reported Titles, records what people doing a job actually called themselves. “Case Manager” appears there for 9 occupations — a separate, narrower relationship collected a different way, reported here rather than merged into the 12 above.

Which kind of case manager is this job?

The title is the one part of a posting that carries no information. Everything under it does.

The job description tells you which of the 12 occupations you are looking at, and it does so through details the title cannot carry:

• Who the caseload is — patients, families, students, benefit claimants, people in treatment
• What the work actually is — assessment, counselling, coordination, advocacy, eligibility determination
• The setting — hospital, clinic, school, agency, government office
• The education the employer states, and whether it is asked for or preferred
• The experience expected, and in what
• Any credential the employer names — theirs to state, not ours to assume

We are not going to pretend a keyword rule maps postings onto these 12 occupations. The source supports no such rule, and inventing one would make this page the sort of confident guess it is arguing against.

Case Manager vs social worker

Both, sometimes. 4 of the 12 occupations that use this title have "Social Worker" in their official occupation title; the other 8 do not — which is exactly why the title alone cannot answer the question.

So the difference between a case manager and a social worker is not a difference between two jobs. Some jobs advertised as case manager sit in occupations O*NET names as social work; others sit in counselling, psychology, programme management, patient advocacy or benefits administration. That split is read straight off the official occupation titles above, not from any judgement of ours about what social work is. O*NET describes what each occupation does and BLS records the education typically needed to enter it — neither says who may hold a particular job title, and this page does not infer it. Licensing and scope of practice are set by states and employers and are not in either source.

How do you become a case manager?

In an order that survives the ambiguity, rather than a universal path that does not exist.

1. 01

   Work out which of these occupations you actually mean

   Of the 12 above, which describes work you want to do — a clinical caseload, programme management, patient advocacy, eligibility determination? Nothing in the data makes that choice for you, but it is the choice every "become a case manager" plan silently assumes you have made.

2. 02

   Read what BLS records about entering that occupation

   Typical entry education is published per occupation and is not the same across these 12: typical entry-level education ranging from high school diploma or equivalent to doctoral or professional degree, most often a bachelor's degree (4 of them), with no row in the table for 2. These are the typical education levels needed for entry.

3. 03

   Check whether experience or on-the-job training is recorded

   BLS records related work experience for 1 of the 12 — Social and Community Service Managers — and none for the rest. That is a real difference between them.

4. 04

   Compare those signals against real postings

   Adverts using this title are the market's own version of the occupation and vary more than the occupational data does. A handful of real ones for the work you picked will show what employers in your area ask for.

5. 05

   Evaluate your own evidence against that specific job

   Not against the occupation in the abstract. The gap that matters is between one employer's stated requirements and what you can actually evidence.

Case Manager requirements and education

There is no one degree requirement for every job called "Case Manager", because there is no one occupation. BLS publishes a typical entry-level education per occupation, and across these 12 it takes 6 different values.

Read that as a description, not a rule. BLS describes these as the typical education levels needed for entry, not universal requirements every employer has to impose. They are not a legal requirement, not a licence, and not a statement about what any individual employer will accept — and not evidence that some other route exists either, because the table does not speak to that.

Occupations here we have a qualification page for

Each reports what that specific occupation rates as important, ordered against the occupations closest to it.

• Am I qualified to be a clinical psychologist?
• Am I qualified to be a mental health counselor?
• Am I qualified to be a social worker?

9 of the 12 occupations have no page here yet. Those are separate occupations with their own published data, not variations on the ones above.

Where every claim on this page comes from

Three sources, three different kinds of claim, kept apart on purpose — because one of them cannot be used to make another's point.

O*NET 30.3 Job Titles— which occupations employers use a job title for

Says: "Case Manager" is used as a job title for these 12 occupations. Does not say they are similar, equivalent, or that one of them is the real one.

O*NET 30.3 Occupation Data— what an occupation is

Supplies the official occupation title and the description quoted on each card above. Nothing here paraphrases an occupation into something the source does not say.

BLS Employment Projections, Table 1.2 (2025-35 projections; 2025 worker characteristics)— typical entry into an occupation

Supplies typical entry-level education, related work experience and on-the-job training per occupation. BLS describes these as the education typically needed to enter an occupation; they are not a requirement, a licence, or a promise about any employer.

What this page does not infer: which occupation any particular job belongs to, who is permitted to hold a job title, what any state requires for licensure, what an employer will accept, or what the work pays. O*NET also publishes a Related Occupations list describing adjacency between occupations; it is a different relationship and is not used here.
