The answer to this question has two parts: (1) how a model is selected for review; and (2) whether HomVEE determines a model meets the criteria established by HHS for an “evidence-based early childhood home visiting service delivery model.”
HomVEE uses a systematic process to select models for review. To identify new research, HomVEE conducts a literature search and issues a call for research. Using the identified research, models are then assigned points based on the (1) number and design of eligible impact studies, (2) sample sizes and sample characteristics of the impact studies, and (3) characteristics of the model. Models are ranked by accumulated points and those with higher rankings are selected for review. For more information on the review process, please see Chapter 2 of the Version 2 Handbook of Procedures and Evidence Standards located on the Methods and Standards section of the website.
After a model is reviewed, HomVEE assesses whether it meets the HHS criteria for an evidence-based model. Regardless of whether the model meets the HHS criteria, information about each reviewed model can be accessed on the HomVEE website via the Model Effectiveness Research Reports section. A list of models HomVEE has reviewed, and whether they meet the HHS criteria, is available in the Home Visiting Model Effects Table.
