Frequently Asked Questions

For models that are not yet evidence based (Track 1), HomVEE will select models to review by calculating a prioritization score using a combination of model and manuscript characteristics. Prioritization scoring assigns points based on various factors, including (1) number and design of eligible impact studies, (2) sample sizes and sample characteristics of the impact studies, and (3) characteristics of the model. After a model is selected for review, HomVEE will apply its latest standards to review all research that is unreviewed or was reviewed under prior standards. See the Handbook of Procedures and Evidence Standards located on the Resources page of the website for the most up to date information on these processes.

Models that are already evidence based (Track 2) are updated based on a predetermined schedule instead of using a prioritization process. Previously reviewed research about these models is not re-reviewed for these updates. The purpose of the Track 2 review is to update existing Model Effectiveness Research Reports and Model Implementation Profiles to keep them current; HomVEE does not reassess a model’s evidence rating based on a Track 2 review.

HomVEE screens all research identified through its annual call for research and literature review to identify which manuscripts are eligible for review according to HomVEE’s published procedures and standards. Specific screening criteria can be found in Chapter 2 of the Handbook of Procedures and Evidence Standards located on the Resources page of the website. Once manuscripts are screened in, manuscripts about impact studies contribute to prioritization scores. Research on models that are not prioritized for review in a given year remains in the HomVEE database for consideration in future years.

Yes, HomVEE issues a call for research every year in August that is open through September. The call is sent to relevant electronic mailing lists and is also posted on the HomVEE website homepage with instructions on how to submit research. Research can be submitted at any time, but if it is submitted outside of the call window, it will be screened the following year.

HomVEE will review new grey literature only if it is publicly available and accessible on a website (this can include a requirement for purchase) or if it is an in-press journal article. Even if the content is publicly available, HomVEE will not review dissertations, theses, conference papers, and manuscripts labeled as working papers or under review. For additional details, please see the Handbook of Procedures and Evidence Standards on the Resources page.

HomVEE aims to treat all models consistently and fairly and to have a complete picture of all observed effects for a model. Therefore, HomVEE has a systematic process for identifying all relevant research and prioritizing models for review based on the available empirical evidence. Accepting new information, studies, or research during the course of the review would significantly delay HomVEE’s annual review process. For these reasons, HomVEE cannot review specific manuscripts on request. More details on this process are available in Chapter 2 of the Handbook of Procedures and Evidence Standards located on the Resources page.

Track 1 early childhood home visiting models are models that HomVEE has not yet found to be evidence-based. Track 2 models are models that HomVEE has already found to be evidence-based. 

HomVEE treats Track 1 and Track 2 models differently. 

HomVEE reviews Track 1 models to determine if they meet HHS criteria for evidence of effectiveness (see FAQ “How does HomVEE apply HHS criteria for evidence-based early childhood service delivery models?” ). During each review for a Track 1 model, HomVEE re-reviews all previously-reviewed research about that model using the latest HomVEE standards. This may result in changes to a manuscript’s rating or eligibility. If a study manuscript no longer meets standards, HomVEE may remove the findings from the website. Based on the most recent review results, HomVEE determines whether a Track 1 model meets the criteria to be evidence-based. 

HomVEE does not re-review Track 2 models but periodically updates their model reports to include the most recent research. Each update uses the current standards to review new research identified since the last update, but does not re-review research. That means that some research on the HomVEE website about Track 2 models might no longer be eligible for review under the latest procedures and standards. Importantly, HomVEE does not reassess Track 2 models against the HHS criteria when it updates their reports. That means Track 2 models retain their evidence-based status.
