Home Instruction for Parents of Preschool Youngsters (HIPPY) is a home-based intervention for parent engagement and kindergarten readiness. Using a quasi-experimental design, this research sought to determine whether the HIPPY intervention increased children's likelihood of passing the Florida Kindergarten Readiness Screener and being promoted to the first grade. The sample included 730 children, of whom 379 participated in the intervention group (i.e., HIPPY) and 351 were identified for the comparison group using propensity score matching techniques. Among families at risk due to poverty and limited English language proficiency, the odds of passing the Florida Kindergarten Readiness Screener were almost two times greater for children whose parents participated in the HIPPY program and their odds of being promoted to the first grade were five times greater than a matched sample of non-participants. This research provides evidence of a successful HIPPY scale-up in real-world contexts and among a diverse sample. The discussion includes implications for policy and directions for future research.

学龄前儿童家长家庭指导（HIPPY）是一项基于家庭的干预，旨在提高父母的敬业度和幼儿园的准备度。本研究采用准实验设计，旨在确定HIPPY干预是否增加了儿童通过佛罗里达幼儿园幼稚园筛查并晋升为一年级的可能性。样本包括730名儿童，其中有379名儿童参加了干预组（即HIPPY），并使用倾向评分匹配技术将351名儿童确定为对照组。在因贫困和英语水平有限而有风险的家庭中，对于父母参加HIPPY计划的孩子，通过佛罗里达幼稚园准备筛查的几率几乎是其两倍，而他们被晋升为一年级的几率是未参加调查的同等样本的五倍。这项研究提供了在真实环境中以及各种样本中成功进行HIPPY放大的证据。讨论内容包括对政策的影响以及未来研究的方向。
