...on ten years ago? When did the EPA start requiring that schools be tested for asbestos?

You could probably ask someone at the building inspector office (in you county), or the state may have that information.

All schools in the USA must have been inspected under the AHERA standard in late 1987 or early 1988 or when first opened after that. From that each school and school system must have a mangement plan that describes how they deal with asbestos. You can contact the school system and review the management plan. You will probably have to go to them to read the document. You may be able to go to the state school group, but that is a much harder process because most of the plans were probably archived.

Have someone with that kind of experience check,like attorney
