Social Work Genogram ​

A caseworker meeting a family for the first time needs a clear picture of who is in the household, which formal systems are involved, and what has repeated across generations. A social work genogram provides all three in one diagram.

What Makes a Social Work Genogram Different ​

A standard genogram maps family structure, health history, and relationship quality. A social work genogram adds:

  • Formal system involvement: CPS history, court involvement, incarceration, foster placements, and housing situations are documented alongside the family structure.
  • Behavioral and relational patterns: substance use, abuse history, and trauma across generations are included where relevant to the assessment.
  • Strengths and resources: a social work genogram is not only a risk map. Resilient relationships, extended family support, community connections, and protective factors are documented alongside concerns.

These additional layers require the same standardized notation and a complete key, since the genogram may be read by other practitioners on the case.

Social Work-Specific Notation ​

Beyond standard McGoldrick notation, social workers use several additional markers:

  • CPS involvement: a dashed red border or CPS label beside the relevant person's symbol indicates child protective services history.
  • Household boundary: a dashed line drawn around all currently cohabiting household members makes the current living situation immediately clear.
  • Foster care: an FC notation or the standard green dotted line indicates a foster placement.
  • Incarceration: a shaded symbol or INC notation indicates a currently incarcerated individual.

Any non-standard notation must appear in the key on the completed genogram. A diagram using these markers without a key is not readable by another practitioner.

For the full standard symbol set, see the genogram symbols guide.

Practice Areas ​

Social workers use genograms across a range of practice settings:

  • Child welfare and CPS: mapping kinship options, placement history, abuse patterns, and custody arrangements.
  • Family services: assessing family functioning, identifying strengths, and planning referrals.
  • Mental health: mapping mental health history across generations and understanding family triggers.
  • Housing and homelessness: identifying extended family housing options and documenting barriers.
  • Legal and court: supporting custody evaluations, documenting for court reports, and tracking compliance.
  • Aging and elder care: mapping caregiving distribution and identifying gaps in support.

What to Include ​

Essential: ​

  • Names and ages of all family members.
  • Dates of births, deaths, marriages, divorces.
  • Household composition; who lives where.
  • Custody and visitation arrangements.
  • Index person marked with a double border.

Enhanced; add where relevant to the assessment: ​

  • Abuse and trauma history
  • Substance use across generations
  • Mental health diagnoses
  • CPS involvement
  • Incarceration history
  • Foster care placements
  • Immigration status where clinically relevant
  • Cultural and religious background

The level of detail depends on the purpose. A child welfare case requires more documentation than a general family services intake.

Genogram and Ecomap in Social Work ​

Most social work assessments benefit from both tools.

  • The genogram maps the family's internal history and relational patterns.
  • The ecomap maps the family's current external environment; support systems, community resources, and stressors.

For a full guide to using both together, see the ecomap and genogram article.

For the ecomap specifically in social work practice, see ecomap social work.

Completed Social Work Genogram Examples ​

The family genograms in the genogram for social work assessment article shows various completed three-generation social work assessment genograms; a child welfare case with CPS involvement, substance use across generations, and elderly kinship care.

The examples include annotations on what each pattern reveals and how the diagrams inform the assessment.

FAQ

How is a genogram used in social work?

Social workers use genograms to map a client's family structure, identify intergenerational patterns, document formal system involvement, and plan interventions. They are used at intake, during case reviews, in court documentation, and in direct work with families. The genogram is completed with the client where possible; the process of drawing it together often surfaces information that doesn't emerge through conversation alone.

What should a social work genogram include?

At minimum, names, ages, household composition, custody arrangements, and the index person. For a fuller assessment, abuse and trauma history, substance use across generations, mental health diagnoses, CPS involvement, incarceration, and foster care placements. What gets included depends on the purpose; a child welfare case, for instance, requires more documentation than a general intake.

What are social work-specific genogram symbols?

Beyond standard McGoldrick notation, social workers use a household boundary line (a dashed line around cohabiting members), CPS involvement markers, foster care notation, and incarceration symbols. These symbols should always appear in the key on any completed diagram so other practitioners can read it.

Do social workers actually use genograms?

Yes. Genograms are standard practice in child welfare, family services, mental health, and elder care social work. They are recognized by NASW as a tool for family-centered practice and are taught in MSW programs as part of assessment methodology.

What is the difference between a genogram and an ecomap in social work?

A genogram maps the family's internal structure and history across generations, such as who is related to whom, relationship quality, health history, and behavioral patterns. An ecomap maps the family's current external environment, such as which community systems they are connected to and how those connections are functioning. Social workers typically use both tools together at intake to build a complete picture of the family's history and present situation.
