With increased constellations throughout the UK, the Department of Education, in collaboration with Oxford University, further evaluated the impacts of Mockingbird Family from October 2017 through March 2020. An initial release of the evaluation showed that when in a constellation:

• 94% of foster families kept fostering.
• 90% of families said they received good or excellent support from other families and hub homes.
• Youth and families in care reported higher levels of well-being.
• Foster Families are more likely to utilize open beds.
• Siblings were more satisfied with the time they spent together, with 10.5% saying that they spend too much time together.
• Young people reported strong social networks, having people they trusted, and a feeling of being part of a community.

The full report was released in November 2020 and contains:

• Cost benefit analysis
• Qualitative data (e.g. satisfaction)
• Quantitative data (e.g. foster parent retention)

After launching their first constellation in 2014, the UK has expanded their Mockingbird Family Constellations across the UK. In 2016, the Department for Education did an initial outcome evaluation for youth who were in the constellation. Initial outcomes found increased sense of peer-support for families and youth, better foster parent retention, and greater placement stability for youth in care.

2016 UK Evaluation Report

The Washington State Institute on Public Policy did a review on outcomes for youth in MOCKINGBIRD FAMILY™ Constellations. In their evaluation on data from 2004 until 2017 they found that youth placed in constellations had greater placement stability in their foster homes. Additionally, 92% of foster families in constellations keep fostering after 2 years, compared to 25% in other areas.*

Following up on the WSIPP outcome evaluation, WSIPP found that 67% of the time, constellations saved more money than they cost. Further research would provide a comprehensive look at financial impact of constellations.
