Why scores improve significantly while in Children's Bureau's Foster Care:

  • Availability of foster parent to nurture foster child-83% of foster families have two or less foster children.

  • Stability of living situation-3 out of 4 children remained with the same foster family during their entire placement history allowing for continuity of foster family relationship, school, and peers.

  • Improved health, nutrition, sleep, assessing need for glasses.

  • Enrichment of verbal and non-verbal skills by the foster family (e.g., through daily interactions, increased verbalization, trips, reading, sports, etc.)

  • Foster parents and Children's Bureau social worker's structuring homework time and providing assistance with school work and projects.

  • Continual reinforcement for school work and behavior

  • Advocacy by Children's Bureau social workers for meeting special needs (e.g., requesting an Individual Education Plan or tutoring)

  • Formal assessments to determine needs with follow-up assessments to measure changes and update the intervention plan

  • Initial and ongoing training, support and monitoring of foster parent by Children's Bureau social workers.

  • Social worker is assigned to 12 foster children and their foster families allowing for sufficient social work support.
