Schools have to meet the testing and product requirements of the California Department of Health Services Standard Practice for the Testing of Volatile Organic Emissions from Various Sources Using Small-Scale Environmental Chambers, including 2004 Addenda. 

This is a chamber test that determines the rate of offgassing for adhesives, sealants, paints, and coatings. This reference standard is much more stringent than the low-emitting standards referenced in other LEED rating systems. Not many products have gone through this testing method, so finding compliant products can be difficult and may include a cost premium.

However, earlier versions of LEED for Schools were able to follow a USGBC (https://www.usgbc.org/ShowFile.aspx?DocumentID=4311) erratum allowing projects to pursue the IEQc4.1 and IEQc4.2 VOC limit compliance path from the NC rating system rather than the California standard. The erratum still applies to LEED for Schools 2009.    

Only 20% of product cut sheets selected at random need to be uploaded to LEED Online to document this credit, although it is best to keep all product cut sheets on file in case the credit is audited.
