TL;DR:
ACS (Administration for Children’s Services) is NYC’s child welfare agency, while CPS (Child Protective Services) refers to similar agencies operating in other states or counties. Both investigate abuse and neglect, offer family services, and can seek court involvement. They share legal mandates and collaborate on complex cases. If contacted by ACS or CPS, stay calm, understand your rights, seek legal support, and document everything carefully.
What is ACS and how does it differ from CPS?
ACS, or the Administration for Children’s Services, is New York City’s municipal agency responsible for overseeing child welfare, juvenile justice, and early childhood services. It plays a central role in protecting infants, supporting families, and running programs that span beyond traditional protection.
CPS, or Child Protective Services, is a broader term used nationwide to describe state or county-level agencies that investigate reports of kids abuse or neglect. CPS agencies work to ensure child safety and family stability, stepping in when infants are at risk.
Differences Between ACS and CPS
| Category | ACS (Administration for Children’s Services) | CPS (Child Protective Services) |
| Governance & Oversight | City-run agency under NYC government | State-governed; typically part of health or human services departments |
| Geographic Scope | Operates exclusively in New York City | Functions in counties or states across the U.S. |
| Service Delivery Model | Uses CARES for non-urgent cases: family-driven, supportive, non-investigatory | Increasing use of “alternative” or “differential” response models for lower-risk cases |
| Legal Powers | Can investigate, provide services, open cases, petition family court, and remove children | Same core legal powers as ACS |
| Unique Procedures | Mandatory home inspections for all reports; centralized system; specific removal policies under legal review | Varies by state; generally follows state-specific procedures |
What ACS Does in Child Welfare
The Administration for Children’s Services (ACS) plays a central role in New York City’s infant welfare system, offering a broad framework of protection, support, and services to ensure kids safety and strengthen families.
- Investigations & Assessments
ACS responds to all reports made to the State Central Register. For each case, initial home visits are conducted within 24–48 hours, and full investigations are completed within 60 days. In less urgent cases, ACS may use the CARES approach, which offers a supportive, non-investigatory pathway focused on family engagement and voluntary services. - Service Provision & Prevention
ACS connects families with a range of services, including mental health support, parenting assistance, housing help, and other wraparound resources. These services aim to address challenges early and prevent foster care placements. Since 2001, the agency has shifted more kids into in-home support than foster care, reflecting a major expansion of preventive services. - Foster Care & Juvenile Justice
When necessary, ACS places them in foster care—either with families or in group settings—and oversees those placements to ensure safety and stability. The agency also facilitates adoption and provides juvenile justice services. ACS has introduced focused initiatives to support vulnerable populations, including LGBTQ youth, survivors of trafficking, and families accessing enrichment centers. - Court Involvement
If a child’s home is determined to be unsafe, ACS may petition Family Court. Through collaboration with its legal team, ACS can request court-ordered supervision or removal to protect the minor, ensuring legal oversight and due process in critical cases.
How CPS Protects Children
CPS agencies across the U.S. follow a structured process to respond to reports of abuse or neglect. Reports come through hotlines, schools, or mandated reporters and are screened to determine the level of risk. Low-risk cases may be diverted to community-based support services, reflecting a non-investigative approach similar to ACS’s CARES model.
For higher-risk cases, the agency conducts home visits, interviews with kids and caregivers, and gathers evidence. In serious situations, CPS may work with law enforcement to ensure immediate safety. Based on their findings, CPS creates safety and treatment plans that may include parenting classes, mental health support, or substance use intervention.
When necessary, CPS can petition the court to request supervision or removal of a kid from the home, though the goal is always reunification if safety can be assured. Even after investigations close, CPS often provides or mandates follow-up services to help maintain long-term family stability and child safety.
How ACS and CPS Work Together
Although ACS and CPS are distinct agencies serving different jurisdictions, they operate with shared goals and often collaborate to protect minors and support families. Their coordination is especially important in complex or cross-jurisdictional cases.
- Joint Investigations
In serious cases such as fatalities or sexual abuse, CPS agencies and law enforcement—including ACS in New York City—may work together to ensure a thorough investigation. These joint efforts help combine resources and expertise to address immediate safety concerns. - Shared Models and Legal Guidelines
ACS’s CARES approach aligns with a broader shift in CPS agencies nationwide toward family-focused, non-investigatory responses in lower-risk cases. Both ACS and CPS operate under federal guidelines set by the Child Abuse Prevention and Treatment Act (CAPTA), as well as their respective state laws covering child removal procedures, confidentiality protections, and appeal rights. - Interagency Communication
When families move between NYC and other parts of the state or country, ACS and CPS agencies coordinate by sharing case information through central registries. This interagency communication ensures continuity of care and monitoring, helping protect infants across jurisdictions.
What to Do If You Are Involved with ACS or CPS
Being contacted by ACS or CPS can feel overwhelming, especially if you’re unfamiliar with how the system works. These agencies are tasked with protecting minors, but that doesn’t mean you’re automatically in trouble. Comprehending your rights and responsibilities, and knowing what steps to take, can help you stay informed, protect your family, and work toward the best possible outcome.
1. Respond Calmly & Cooperatively
ACS and CPS are there to assess kids safety—not to punish. Staying calm and respectful can help the process. You may allow caseworkers into your home voluntarily, but remember they can request court authorization if you refuse.
2. Understand Your Rights
You have the right to ask questions about the investigation, including whether any removal is voluntary or court-ordered, and how to challenge a finding. Knowing your rights helps you make informed choices throughout the process.
3. Seek Support Services
Even if your case is ultimately unfounded, you may still be eligible for support services such as parenting programs or housing assistance. Taking advantage of these resources can show your willingness to cooperate and improve outcomes.
4. Legal Advocacy
If a court case is filed or removal is threatened, it’s important to have legal representation. A lawyer can help you navigate the system, challenge agency findings, and file appeals if necessary.
5. Keep Documentation
Maintain thorough records of any interactions with the agency—this includes notes from home visits, services provided, and agreements made. These documents can be valuable in court or during appeals.
6. Appeal & Expunge
If your case is marked “indicated,” you typically have the right to appeal the decision. In New York City, indicated reports of maltreatment that don’t involve abuse may be eligible for expungement after eight years.

ACS is a city-run agency under the NYC government, while CPS is state-governed. ACS serves only NYC; CPS operates in various counties and states nationwide. - Service Models:

CPS receives reports, screens for risk, investigates when needed, partners with law enforcement in serious cases, offers safety plans, petitions courts if required, and continues support post-investigation. - Collaboration Between ACS and CPS:
They may work jointly on severe cases. Both follow federal CAPTA rules and coordinate when families cross jurisdictions, sharing case data through central registries. - What to Do If Involved:
Stay calm and cooperative. Understand your legal rights, ask questions, and seek support services. Hire a lawyer if a court is involved. Keep documentation, and if a case is indicated, explore appeal or expungement options.
