A guide for MSW students entering the field of child welfare.

The foster care system in America is a complex and multifaceted network designed to protect and support children who can’t remain in their homes due to abuse, neglect, or other family issues. 

For social workers considering earning a Master of Social Work (MSW) degree, gaining a deep understanding of the American foster care system is essential. This knowledge prepares future practitioners to advocate for children’s well-being and help families and communities move toward stability and healing.

To help you build a solid foundation for this important work, here are 10 key things every social worker should know about the foster care system:

  1. The Purpose of Foster Care
    The primary purpose of foster care is to provide a safe and nurturing environment for children who have been removed from their homes out of concern for their welfare. The foster care system is designed to be a temporary solution, with the ultimate goal of reunifying children with their biological parents or finding them a permanent adoptive home.
  2. The Number of Children in Foster Care
    According to the Adoption and Foster Care Analysis and Reporting System (AFCARS), there were more than 328,963 children in foster care in the United States as of September 30, 2024. This number has declined annually since 2019, when 425,974 children were in foster care in September of that year.1

  3. The Demographics of Children in Foster Care
    As you’ll learn when you earn an MSW, children in the American foster care system come from diverse backgrounds. Using this information, you can learn to recognize patterns, advocate effectively, and provide culturally responsive care.

    Here are some key data points about children in foster care:

    • 58% of children in the foster care system are age 10 or younger.2
    • 40% of children in foster care are white (non-Hispanic), 25% are African American or Black, and 21% are Hispanic.2
    • 39% of children in foster care live with a relative, 28% live with a non-relative, and 9% live in a therapeutic setting.3
    • Circumstances leading to children’s removal from their homes include neglect (63%) and parental substance use (36%), among others.4
  4. The Role of Social Workers in Foster Care
    All types of social workers play important roles in the American foster care system. Their responsibilities are numerous and varied. Some of those critical duties are:5
    • Assessing the needs of children and families
    • Developing and implementing case plans
    • Helping families navigate the child welfare system
    • Providing support and guidance to foster families
    • Facilitating reunification or adoption

  5. The Challenges Social Workers Face in Child Welfare
    Working within the American foster care system can be incredibly rewarding, but it also comes with challenges. Social workers may find themselves balancing the needs of children, families, and the system itself.

    These challenges can include:

    • High caseloads
    • Limited financial resources
    • Emotional demands
    • Limited access to services and support for children and families

  6. The Importance of Trauma-Informed Care
    Trauma-informed care in social work acknowledges the prevalence of trauma in clients’ lives and is designed to create a safe, supportive environment that avoids re-traumatization. This type of care is key when working with children in the foster care system, as many have experienced adversity, loss, and instability.

    In social work practice, trauma-informed care requires that practitioners:6

    • Understands the impact of trauma on child development.
    • Provide sensitive and supportive services.
    • Create a safe and supportive environment.
  7. The Role of Foster Parents
    Foster parents provide essential care and emotional support for children in foster care. Social workers work with them, and independently, to address children’s needs. These efforts include:
    • Providing training and support
    • Developing and implementing case plans
    • Ensuring the needs of children are met
  8. The Need of Permanency
    Permanency is a critical aspect of the foster care system. The goal is to provide children with a stable and loving forever family. Social workers strive to achieve permanency through reunification with biological parents, adoption, and guardianship.
  9. The Impact of Substance Abuse on Children
    When parents experience addiction, it can lead to instability at home and, in some cases, children entering foster care. Social workers play a key role in helping families find support and build stronger foundations. In the field, this means social work professionals must:8
    • Recognize patterns between substance use and family challenges.
    • Support recovery with access to treatment and community help.
    • Strengthen families by promoting safe, stable homes.
  10. The Need for Collaboration and Coordination
    Collaboration and coordination are essential in the foster care system, with social workers working closely with other professionals, including healthcare providers, educators, court officials, and foster parents.

Accreditation
Walden University’s Master of Social Work (MSW) program is accredited by the Council on Social Work Education’s (CSWE) Board of Accreditation (BOA). Accreditation of a baccalaureate or master’s social work program by the CSWE-BOA indicates that it meets or exceeds criteria for the assessment of program quality evaluated through a peer review process. An accredited program has sufficient resources to meet its mission and goals and the BOA has verified that it demonstrates compliance with all sections of the Educational Policy and Accreditation Standards.

Note on Licensure
The Walden University Master of Social Work (MSW) program is designed to prepare graduates to practice as licensed social workers in many states. However, the requirements for licensure as a social worker vary greatly from state to state. Each state board that is responsible for regulating the practice of social work has its own academic requirements and issues its own license to practice as a social worker in that state. Additionally, students should be advised that the Walden MSW program is not designed or intended to prepare graduates for licensure as a school social worker; however, graduates might be eligible for licensure as a school social worker in their particular state of residence.

While Walden Enrollment Specialists can provide general information relating to the state-by-state educational requirements for social work licensure or certification, it remains the student’s responsibility to understand, evaluate, and comply with all requirements relating to field education experiences, licensing or certification, authorization, or endorsement for the state in which she or he resides. Walden makes no representations or guarantee that completion of its coursework or programs will permit an individual to obtain state licensure, certification, authorization, endorsement, or other state credential. Licensure eligibility determinations are ultimately determined by the appropriate state board that issues the credential to practice.

Prospective students enrolling in licensure-leading programs are advised that relocation to another state may impact the student’s ability to complete field experiences and/or to obtain professional licensure, certification, or other credential in another state. Prospective students are advised to carefully review, evaluate, and understand the requirements of the applicable licensure board in the state in which they intend to relocate.

Walden University is accredited by the Higher Learning Commission (www.hlcommission.org), an institutional accreditation agency recognized by the U.S. Department of Education.
