Agents of Change ASWB exam prep has helped 100,000+ social workers pass, with video and audio lessons, hundreds of practice questions, and live study groups. Start with 10 free practice questions.
The family life cycle describes the predictable stages families move through over time, from young adults leaving home to families in later life, and the changes each transition demands. It’s a core framework for family assessment in social work, and it appears on the ASWB exam in scenarios that ask you to identify a family’s stage, the developmental task it faces, or the intervention that fits.
In this guide, we’ll cover the six stages of the family life cycle as described by Betty Carter and Monica McGoldrick, the emotional process and key tasks of each stage, how divorce and remarriage fit in, horizontal and vertical stressors, and how these ideas show up on the exam. You’ll finish with four practice questions.
Quick answer: the 6 stages of the family life cycle (Carter and McGoldrick)
- Leaving home: single young adults
- The joining of families: the new couple
- Families with young children
- Families with adolescents
- Launching children and moving on
- Families in later life
Each transition requires the family to reorganize its roles, relationships, and boundaries. Stress tends to rise at the points of transition between stages.

1) What Is the Family Life Cycle?
The family life cycle views the family as a system that moves through time together. As members are born, grow up, leave, partner, age, and die, the family has to reorganize. Each stage brings new roles, new relationships, and new tasks, and the family’s stress is often highest at the points of transition between stages.
Sociologist Evelyn Duvall described an early eight-stage model in the 1950s, built around the ages of the oldest child. The model most often used in social work and family therapy, and the one to know for the ASWB exam, comes from Betty Carter and Monica McGoldrick, whose work (later expanded with Nydia Garcia-Preto) describes six stages and the emotional shifts each one requires. Their model is grounded in family systems theory and gives special attention to culture, gender, class, and the many ways real families vary from the “traditional” pattern.
Key ideas in the Carter and McGoldrick model
- Emotional process of transition: Each stage has a key emotional shift the family must make, such as accepting new members or accepting exits from the family.
- Second-order changes: To move forward, the family must change its structure and rules, not just adjust behavior within the old structure. For example, parents must shift from controlling a young child to allowing an adolescent more independence.
- Horizontal and vertical stressors: Families face stress from moving through time and from patterns passed down through generations (explained in section 4).
2) The Six Stages of the Family Life Cycle
| Stage | Key emotional process | Changes the family must make |
|---|---|---|
| 1. Leaving home: single young adults | Accepting emotional and financial responsibility for self | Differentiating from the family of origin; developing intimate peer relationships; establishing self in work and financial independence |
| 2. Joining of families: the new couple | Commitment to a new system | Forming the couple system; realigning relationships with extended family and friends to include the partner |
| 3. Families with young children | Accepting new members into the system | Making space for children in the couple relationship; sharing childrearing, financial, and household tasks; realigning with extended family to include parenting and grandparenting roles |
| 4. Families with adolescents | Increasing flexibility of family boundaries to allow for adolescents’ independence and grandparents’ frailties | Letting adolescents move in and out of the family system; refocusing on midlife couple and career issues; beginning to care for the older generation |
| 5. Launching children and moving on | Accepting many exits from and entries into the family system | Renegotiating the couple relationship as a dyad; developing adult-to-adult relationships with grown children; including in-laws and grandchildren; coping with the disability and death of their own parents |
| 6. Families in later life | Accepting the shifting of generational roles | Maintaining functioning in the face of physical decline; supporting a more central role for the middle generation; making room for the wisdom of older adults; coping with the loss of a spouse, siblings, and peers; preparing for one’s own death |
Stage 1: Leaving home (single young adults)
Young adults separate from their family of origin and take emotional and financial responsibility for themselves. The key task is differentiation: becoming an independent adult while staying connected to family. Common challenges include financial stress, career decisions, building a social network, and either cutting off from family or staying overly dependent. Social workers can support career and life planning, mental health, and healthy connection with family.
Stage 2: The joining of families (the new couple)
Two people form a committed partnership, through marriage or otherwise, and each family of origin has to make room for a new member. Couples negotiate roles, finances, communication, and boundaries with in-laws. Social workers can help couples build communication and conflict-resolution skills and work through loyalty conflicts with extended family. For a closer look at couple development, see Theories of Couples Development and the ASWB Exam.
Stage 3: Families with young children
The family reorganizes to make space for children. Partners become parents, divide childcare and household work, and grandparents take on new roles. Stress often comes from sleep deprivation, role strain, finances, balancing work and family, and the couple relationship taking a back seat. Social workers may offer parenting education, connect families with community resources, and support the couple relationship.
Stage 4: Families with adolescents
Family boundaries need to become more flexible. Adolescents move in and out of the family as they build their own identities, while parents often face midlife career and relationship questions and begin caring for their own aging parents (sometimes called the “sandwich generation”). Parent-teen conflict is common and often developmentally normal. Social workers can facilitate family communication, help parents balance limits with autonomy, and address school or emotional concerns.
Stage 5: Launching children and moving on
This is often the longest stage. Children leave home, and later partners, in-laws, and grandchildren join. Parents renegotiate their relationship as a couple, build adult-to-adult relationships with grown children, and often cope with the illness and death of their own parents. Some parents experience sadness or loss of purpose, sometimes called “empty nest” feelings. Social workers can support role transitions, help couples reconnect, and support caregiving and grief.
Stage 6: Families in later life
Older adults adjust to retirement, physical changes, and the loss of a spouse, siblings, and friends, while the middle generation takes a more central role. Families may face caregiving decisions, changes in living arrangements, and end-of-life planning. Social workers support caregiving, connect families to aging services, provide grief support, and help families make care decisions that respect older adults’ autonomy and wisdom.
3) Variations: Divorce, Remarriage, and Diverse Family Forms
Real families don’t always follow the six stages in order. Carter and McGoldrick described divorce and remarriage as additional phases that interrupt and complicate the life cycle, each with its own emotional tasks:
- Divorce: Deciding to divorce, planning the breakup of the system, separating, and completing the divorce. Key tasks include accepting one’s own part in the end of the marriage, cooperating on parenting and finances, and mourning the loss of the intact family.
- Post-divorce and single-parent families: Maintaining parenting roles and flexible arrangements for children’s contact with both parents, and rebuilding one’s own life and support network.
- Remarriage and blended (stepfamilies): Entering a new relationship, planning a new family structure, and remarrying. Key tasks include tolerating ambiguity about roles, creating new boundaries, and making room for relationships with children’s other parents and extended families.
The model also has to stretch to fit single-parent families, same-sex couples, multigenerational households, families who adopt or foster, couples without children, and cultures where young adults remain in the family home until marriage or longer. On the exam and in practice, avoid assuming that a family that doesn’t follow the “typical” sequence is dysfunctional.
4) Horizontal and Vertical Stressors
Carter and McGoldrick described two kinds of stress that flow through a family:
- Horizontal stressors come from moving forward through time. They include predictable developmental transitions, like the birth of a child or a child leaving home, and unpredictable events, like an untimely death, a serious illness, a job loss, or a disaster.
- Vertical stressors come from patterns passed down through generations: family attitudes, expectations, secrets, labels, and legacies, as well as larger social forces like racism, poverty, and other forms of oppression.
When a horizontal stressor (like a teen’s push for independence) hits a family that already carries vertical stress around that issue (like a multigenerational history of cutoffs when children leave), anxiety in the system rises sharply. This is a useful lens for assessment, and it connects to family systems and Bowen theory.

5) How the Family Life Cycle Shows Up on the ASWB Exam
The family life cycle appears mainly in the Assessment and Planning and Intervention and Practice content areas of the new ASWB exam. Expect scenario questions rather than definitions. Common question types include:
Identifying the stage
A question describes a family’s ages and recent changes and asks which stage they’re in. Look for clues like a first baby, a teenager pushing limits, the youngest child leaving for college, or a recent retirement or loss.
Identifying the developmental task
A question asks what the family needs to work on now. Match the task to the stage: differentiation (leaving home), forming the couple system (new couple), making space for children (young children), flexible boundaries (adolescents), renegotiating the couple relationship (launching), or adjusting to generational shifts (later life).
Choosing the intervention
A question asks what the social worker should do. The best answer usually fits both the stage and the presenting problem, and often normalizes stress that is tied to a developmental transition rather than treating it as individual pathology.
Applying cultural humility
A question may describe a family whose transitions differ from the traditional model, such as adult children living at home by cultural preference. The best answer respects the family’s values and avoids imposing assumptions about how families “should” develop.
Three questions to ask yourself
- What stage is this family in, based on the clues?
- What transition or task is causing stress right now?
- Which answer supports that task while respecting the family’s culture and structure?
The family life cycle is easy to confuse with individual development theories. The family life cycle focuses on the whole family system; Erikson focuses on the individual’s psychosocial tasks; couple development theories focus on the partnership. Use our human development theorist comparison table to tell them apart, and see Erik Erikson and the ASWB Exam and Mahler’s Theory and the ASWB Exam.
6) Practice Questions: The Family Life Cycle
Question 1: Maria and Jose have been married for 22 years. Their son, 20, recently moved out for college, and their daughter, 18, is moving to another city for a job next month. Maria tells the social worker she feels sad and that her role as a mother is shrinking. Jose has been spending more time on hobbies and with Maria. Both are unsure what their relationship will look like with an empty nest. Which stage are they navigating, and what is their PRIMARY task?
A) Families with adolescents: adjusting to teenagers’ need for autonomy
B) Launching children and moving on: renegotiating the couple relationship
C) Families in later life: adapting to physical decline
D) Families with young children: making space for children
Answer: B
Rationale: Children leaving home for college and work marks the launching stage, and a central task is renegotiating the couple relationship as a dyad. Maria’s sense of loss and Jose’s shift toward time with Maria reflect that adjustment. The other options describe stages that don’t fit this family.
Question 2: Parents of a 15-year-old tell the social worker they argue constantly with their son about curfew and friends. They’re also caring for the father’s mother, who recently moved in after a fall. What is the MOST important task for this family’s current stage?
A) Increasing the flexibility of family boundaries
B) Establishing stricter rules to restore control
C) Differentiating from the family of origin
Answer: A
Rationale: Families with adolescents need to make boundaries more flexible, allowing the teen to move in and out of the family while also beginning to care for the older generation. Stricter rules (B) work against this task, and differentiation from the family of origin (C) is the task of young adults leaving home.
Question 3: A couple married eight months ago seeks help because they argue about how often to visit each partner’s parents and whose holiday traditions to follow. Which response BEST fits their family life cycle stage?
A) Explore each partner’s family-of-origin expectations and help them define their own couple boundaries with extended family
B) Refer each partner to individual therapy to address personal issues
C) Recommend they limit contact with both families for the first year
Answer: A
Rationale: The new couple’s task is forming the couple system and realigning relationships with extended family to include the partner. Helping them understand each family’s expectations and define shared boundaries addresses that task directly. Individual therapy (B) misses the system-level issue, and cutting off families (C) doesn’t build healthy realigned relationships.
Question 4: A social worker is working with a family whose 26-year-old daughter lives at home while working full time. In the family’s culture, adult children typically live with their parents until marriage. The daughter and parents report no concerns about this arrangement. What should the social worker do?
A) Encourage the daughter to move out to complete the leaving-home stage
B) Respect the arrangement as consistent with the family’s cultural values
C) Assess the family for enmeshment
D) Explore whether the parents are preventing the daughter’s independence
Answer: B
Rationale: Family life cycle stages vary across cultures, and nothing in the scenario suggests a problem. The family reports satisfaction, and the arrangement fits their values. Assuming dysfunction (A, C, D) imposes a single cultural model on the family.
7) Why the Family Life Cycle Matters in Practice
Beyond the exam, the family life cycle helps social workers:
- Normalize stress: Recognize when conflict or sadness is tied to a developmental transition, like new parenthood or a teen’s push for independence, rather than individual pathology.
- Time interventions: Choose supports that fit the stage, such as parenting education for young families, communication work for families with teens, or caregiving and grief support in later life.
- See the bigger picture: Use horizontal and vertical stressors to understand why some transitions hit a family harder than others.
- Practice cultural humility: Recognize that culture, class, family structure, and life circumstances shape how and when families move through each stage.
8) FAQs: The Family Life Cycle and the ASWB Exam
Q: What are the stages of the family life cycle?
A: In the Carter and McGoldrick model, the six stages are: leaving home (single young adults), the joining of families through marriage or partnership (the new couple), families with young children, families with adolescents, launching children and moving on, and families in later life.
Q: Who developed the family life cycle model?
A: Evelyn Duvall described an early eight-stage model in the 1950s. The model most used in social work comes from Betty Carter and Monica McGoldrick, later expanded with Nydia Garcia-Preto, and it emphasizes the emotional processes of each transition and diversity in family forms.
Q: What are horizontal and vertical stressors?
A: Horizontal stressors come from moving through time, both predictable transitions (like a child leaving home) and unpredictable events (like an untimely death). Vertical stressors are patterns passed down through generations, such as family attitudes, secrets, and legacies, along with social forces like racism and poverty.
Q: Where do divorce and remarriage fit in?
A: Carter and McGoldrick described divorce, post-divorce, and remarriage as additional phases with their own emotional tasks, such as mourning the loss of the intact family, cooperating on parenting, and building new stepfamily boundaries.
Q: How is the family life cycle different from Erikson’s stages?
A: Erikson’s stages describe an individual’s psychosocial development across the lifespan. The family life cycle describes how the whole family system changes as members join, grow, leave, and age.
9) Conclusion
The family life cycle gives you a map of how families change over time and why transitions are often the most stressful moments. For the ASWB exam, know the six stages in order, the key task of each, and how divorce, remarriage, and culture create variations. In scenario questions, identify the stage, name the task, and choose the answer that supports the family through that transition while respecting its culture and structure.
