Evidence of Effectiveness

Since its creation by a family court judge in Seattle, Court Appointed Special Advocates has become one of the most effective programs of its kind. Today there are 949 CASA programs around the country. It is a unique blend of private support, public need and the kind of people power that comes from more than 76,000 volunteers all committed to the rights of every child in the foster care and child welfare system.


Requests for Information/Letters of Intent Sought by April 9, 2018

National CASA seeks national research partners to conduct studies of evidence-based practices. Key in the delivery of “best-interest advocacy” is the role of the judges and the effectiveness of the volunteers resulting in child outcomes of permanence, safety, and the opportunity to thrive. Much like mentoring which has documented and measured match, dosage and types of mentoring, National CASA seeks to fully affirm “best-interest advocacy” as an evidence-based intervention.

We currently are seeking a research partner to conduct a Judges' Perspective Study as the first in a series of studies.

Key Outcomes for the CASA/GAL Model

A child with a CASA/GAL volunteer is more likely to find a safe, permanent home:

  • More likely to be adopted (8, 9, 10, 11, 14)
  • Half as likely to reenter foster care (8, 11, 14)
  • Substantially less likely to spend time in long-term foster care (14)
  • More likely to have a plan for permanency, especially children of color (17)

Children with CASA volunteers get more help while in the system...

  • More services are ordered for the children (1, 2, 6, 7, 8, 9, 14)

... and are more likely to have a consistent, responsible adult presence. (1, 2, 12)

  • Volunteers spend significantly more time with the child than a paid guardian ad litem. (2)

Children with CASA volunteers spend less time in foster care... (15, 16)

  • “It is quite remarkable that children without CASA involvement are spending an average of
    over eight months longer in care, compared to children having CASA involvement.” (15)

... and are less likely to be bounced from home to home. (13, 15, 16)

  • CASA volunteers improve representation of children (18)
  • Reduce the time needed by lawyers (12)
  • More likely than paid lawyers to file written reports (3, 4, 5)
  • For each of nine duties, judges rated CASA/GAL volunteers more highly than attorneys (12)
  • Highly effective in having their recommendations adopted by the court (1)

Children with CASA volunteers do better in school... (13)

  • More likely to pass all courses
  • Less likely to have poor conduct in school
  • Less likely to be expelled

... and score better on nine protective factors (13)

  • Neighborhood resources, interested adults, sense of acceptance, controls against deviant behavior, models of conventional behavior, positive attitude towards the future, valuing achievement, ability to work with others and ability to work out conflicts
