Meets DHHS criteria for an evidenced based model

Evidence of Program Model Effectiveness

This program model meets the criteria established by the Department of Health and Human Services (DHHS) for an “evidence-based early childhood home visiting service delivery model” for the general population, but does not meet the criteria for tribal populations.


Program Model Description

Home Instruction for Parents of Preschool Youngsters (HIPPY) aims to promote preschoolers’ school readiness and support parents as their children’s first teacher by providing instruction in the home. The program model is designed for parents who lack confidence in their ability to prepare their children for school, including parents with past negative school experiences or limited financial resources. HIPPY offers weekly, hour-long home visits for 30 weeks per year, and two-hour group meetings at least six times per year. HIPPY sites are encouraged to offer the three-year program model serving 3- to 5-year olds, but can offer a two-year program model. The home visiting paraprofessionals are typically drawn from the same population that is served by a HIPPY site, and each site is staffed by a professional program coordinator who oversees implementation and supervises the home visitors. For more information, please read the Program Model Overview.

Criteria Established by the Department of Health and Human Services

Information Based on Comprehensive Review of All High- and Moderate-Impact Studies for this Model
High- or moderate-quality impact study? Yes
Across high- or moderate-quality studies, favorable impacts in…
   at least two outcome domains within one sample
   the same domain for at least two non-overlapping samples?
Favorable impacts on full sample? Yes
Any favorable impacts on outcome measures sustained at least 12 months after program enrollment?a Yes
One or more favorable, statistically significant impact reported in a peer-reviewed journal?a Yes

aThis information is reported for all program models, but the requirements for sustained findings and inclusion in a peer-reviewed journal only apply to models for which all findings are from randomized controlled trials.
