The following is a list of acronyms and initialisms used by Child Support Services. This list has been revised as of July 2026. Some of the items on the list are linked to articles with item definitions. This is merely a list, not a glossary of definitions.
If more detailed definitions are needed, access Definitions – Glossary of Child Support Terms or other dictionary-type directories.
You can also access the federal Office of Child Support Services (OCSS) Glossary of Common Child Support Terms page. The federal resource defines a list of acronyms and other terms used by child support workers.
