The Children's Adoption Resource Exchange is not the only adoption agency in the Washington area devoted primarily to finding homes for children considered hard to place, as was incorrectly stated in last week's District Weekly.

Two other adoption agencies and the D.C. Department of Human Services also work primarily with hard-to-place children.

Peirce-Warwick Adoption Services, 5229 Connecticut Ave. NW, works only with hard-to-place children, according to the director, Helen Marek. The agency finds parents for black children over age 5, especially boys (who Marek said are more difficult to place), sibling groups and a smaller number of handicapped white children.

In 1982, Peirce-Warwick placed 20 children, 10 of whom had emotional or physical disabilities ranging from retardation to hydrocephaly, Marek said. The agency does not charge adoptive parents for the cost of placing the child.

Family and Child Services, 929 L St. NW, also works with older and handicapped children, primarily black, according to the director, John Theban. The agency has a contract with the District's Department of Human Services to find homes for older children in foster care, and has in foster care 110 children, average age 12, whom it is trying to place with families. In l982, the agency placed 46 children; approximately one-third were handicapped, Theban said.

Most children in the custody of the D.C. Department of Human Services who were adopted in fiscal year 1982 were also hard-to-place children, according to acting chief of child and family services Norma Jernigan. Last year, of approximately 90 District children who were adopted, 54 were either over age 5 or handicapped, Jernigan said.

The article also stated incorrectly that the Children's Adoption Resource Exchange places children from the Washington area. The children for whom the agency finds homes come from throughout the eastern United States
