No. A model may be evidence-based, according to HHS criteria, on the strength of either RCT research or QED research (including non-experimental comparison group, single-case, and regression discontinuity designs). The research must be of moderate or high quality based on HomVEE’s published standards. Additional HHS criteria apply when the research uses an RCT design. For details, please see the HHS criteria for evidence-based early childhood home visiting service delivery models.
