Often, writing a cover letter to go with a study that is going to a PARTICULAR worker for a CERTAIN child or sibling group is a good plan.
This letter should be addressed to the social worker of the children. You may not know their name, but it could be simply: Dear Caseworker of Joe and Mary.
In this letter, based on the description of the children, you can write why you the children would fit into your home. Show how some of their interests match yours. Conclude with a statement of commitment once again.
When you ask your worker to send your study, let her know that you have a letter made up to go with your profile and your home study. Sending this can often make a direct tie to the children.
