what do SERVICE RATINGS mean?

According to the IV-E Clearinghouse website:

Using the qualifying contrasts [of studies reviewed], reviewers assign one of four ratings to each program or service to characterize the extent of evidence for a particular program or service:

• Well-supported. A program or service is rated as a well-supported practice if it has at least two contrasts with non-overlapping samples in studies carried out in usual care or practice settings (see Section 6.2.2) that achieve a rating of moderate or high on design and execution and demonstrate favorable effects in a target outcome domain. At least one of the contrasts must demonstrate a sustained favorable effect of at least 12 months beyond the end of treatment (see Section 6.2.3) on at least one target outcome.

• Supported. A program or service is rated as a supported practice if it has at least one contrast in a study carried out in a usual care or practice setting that achieves a rating of moderate or high on design and execution and demonstrates a sustained favorable effect of at least 6 months beyond the end of treatment on at least one target outcome.

Other reviewer designations include Promising, and Does not currently meet criteria.

acf.hhs.gov indicates, the [FFA] requires that state title IV-E prevention services must be rated promising, supported, or well-supported in accordance with Department of Health and Human Services (HHS) criteria and be approved by HHS. The Children’s Bureau issued ACYF-CB-PI-19-06 to provide instruction on the procedures to claim transitional payments for services and associated costs under the title IV-E prevention program until the Prevention Services Clearinghouse can review and rate the program or service.
