Discussion 2: Child Welfare and Family Preservation
An essential aspect of social work practice is the support and preservation of the family unit. Building and empowering strong, resilient families is a focus of social work practice within organizations and communities.
Social work research is an integral aspect of working with families. The research component of social work is essential to providing effective policies, programs, and services to support and empower families.
As a social worker, you need to be equipped with the knowledge and skills required for effectively working with families for child welfare. You also need to interpret and evaluate research findings involving family and child welfare.
For this Discussion, review this week’s resources. Consider the role of family preservation in child welfare, the research regarding family preservation, and the assumptions about foster care. Think about whether you agree with the research, and whether there are any gaps in your state foster care system that might contribute to the assumptions. Reflect on the benefits and shortfalls of permanency planning and family preservation and which approach you prefer.
Post 
1-An explanation of the role of family preservation in child welfare. Then, explain whether research supports the assumption that foster care is harmful for children, as presented by the cornerstone argument for family preservation. Be sure to include whether you agree with this assumption and why you agree or disagree. 
2-Subsequently, identify the gaps in your (Maryland) state foster care system that contribute to the idea that foster care is harmful to children. Then, compare the benefits and shortfalls of permanency planning and family preservation. 
3-Finally, provide a description of whether you prefer the permanency or the family preservation approach as a child welfare social worker and why you prefer it.
Support your post with specific references to the resources. Be sure to provide full APA citations for your references.
