Family Preservation Programs: What the Evidence Says About Keeping Children Home

Every year, thousands of children enter out-of-home care, and the caseworkers and directors making those decisions do so with limited time and too few good options. Behind every placement decision is a child whose world is about to change, and a family who may have been one well-timed service away from staying together.

That’s why the evidence on family preservation matters. Not as an abstract policy debate, but as a practical guide to where prevention can actually keep kids safely at home, where strong implementation makes the difference, and what infrastructure agencies need to support families and draw down the federal reimbursement already set aside for this work.

What Are Family Preservation Programs?

Family preservation programs are services designed to help children remain safely at home with their families rather than enter out-of-home care. They’re distinct from family reunification, which serves children already in care and works to bring them home. Preservation sustains families; reunification reconnects them.

In practice, “family preservation program” refers to two different service tracks:

• Intensive family preservation services (IFPS) are short-term crisis interventions for families where a child is at imminent risk of separation. Caseloads are small, service periods are brief, and therapists are available around the clock. Determining the level of risk requires ongoing safety assessment and careful clinical judgment throughout the entire service period.
• Ongoing in-home support serves families in which a safety concern has been substantiated, but separation isn’t imminent. Caseworkers visit periodically, connect families to community services, and monitor risk over months or longer at standard agency caseload ratios.

FFPSA made Title IV-E reimbursement for prevention services optional, but eligibility for funding is narrow. Here’s what the evidence actually says about which of these programs work, and under what conditions.

The Evidence Base Behind Family Preservation Programs

The evidence shows that family preservation can reduce out-of-home placement, with the strongest effects coming from specific models delivered with high fidelity.

1. IFPS Reduce Out-of-Home Placement at Multiple Follow-Up Points

A 2020 systematic review of 33 studies involving more than 30,000 children found significant reductions in the relative risk of out-of-home placement among children whose families received IFPS compared with those who received standard services. The effect held at relative risk values of around 0.51 to 0.60 across 3-, 6-, 12-, and 24-month follow-up points, sustained over time rather than fading after the intervention ended. A relative risk of 0.51 at six months means children whose families received IFPS were placed in out-of-home care at roughly half the rate of comparison children, with that reduction holding at later follow-up windows.

2. Fidelity to the Homebuilders Model Determines Whether the Reduction Holds

A Washington State Institute analysis of 14 IFPS evaluations sorted programs by adherence to the Homebuilders model, which carries a well-supported Clearinghouse rating.

Developed in the 1970s in Washington State, Homebuilders places therapists with families in their homes for 4-6 weeks, with caseloads of 2 families at a time and 24/7 availability, structural conditions that allow intensive, relationship-based intervention to take hold.

The four programs in the analysis that documented at least 13 of 16 essential model components reduced out-of-home placements by approximately 31 percent and reduced subsequent verified reports of child abuse and neglect. The 10 programs that documented five or fewer components showed no significant effect on either outcome.

3. Nurse-Family Partnership Reduces Verified Abuse and Neglect Over the Long Term

The Nurse-Family Partnership (NFP) is a home-visiting program that pairs registered nurses with low-income, first-time mothers from early pregnancy through the child’s second birthday. The focus is on improving prenatal health, early childhood development, and parenting skills before any child welfare involvement begins.

NFP has been evaluated in multiple randomized controlled trials. In the 15-year follow-up of the Elmira trial published in JAMA, nurse-visited children of low-income, unmarried mothers experienced 48 percent fewer verified incidents of child abuse and neglect than the control group, with the strongest findings reported among the highest-risk families.

4. Most State Prevention Plans Concentrate Around the Same Eight Programs

As of March 2026, the Title IV-E Prevention Services Clearinghouse had rated 100 programs across 219 reviewed. Twenty-seven appear in at least one approved state prevention plan, and eight dominate the rest: Motivational Interviewing (32 jurisdictions), Parents as Teachers (31), Functional Family Therapy (25), Multisystemic Therapy (24), Healthy Families America (23), Parent-Child Interaction Therapy (21), Homebuilders (20), and Nurse-Family Partnership (16).

5. Title IV-E Prevention Reimbursement Is Not Consistently Reaching Jurisdictions

As of FY 2023, 19 of 48 jurisdictions with approved Title IV-E prevention plans had ever submitted claims for prevention services. The remaining 60 percent had never submitted any. Preliminary FY 2024 and FY 2025 data referenced in the same brief indicate that, while additional jurisdictions have continued to claim over time, roughly one-quarter have not yet.

6. A Clearinghouse Rating Does Not Certify Operational Readiness

A Clearinghouse rating certifies the quality of the research behind a program, but doesn’t tell you whether your agency has the infrastructure to deliver that program.

The Infrastructure Behind Programs That Actually Change Outcomes for Children

Here’s the through-line across every finding above: the evidence base is clear, the reimbursement is authorized, and the programs are rated, but children only feel the difference when agencies have the infrastructure to deliver these services with fidelity, document them accurately, and claim the federal funding that sustains them.

Strengthen Your Family Preservation Program with the Right Technology

The difference between a prevention plan on paper and a prevention system that keeps children safely at home almost always comes down to infrastructure. Without the data, documentation, and fidelity tracking to back it up, even the strongest evidence-based models struggle to reach the children they were designed for.
