The United States Small Business Administration (SBA) is increasing 37 small business size standards for 34 industries and three sub-industries ("exceptions" in SBA's table of small business size standards) in North American Industry Classification System (NAICS) Sector 54, Professional, Technical, and Scientific Services. SBA is also increasing the one size standard in NAICS Sector 81, Other Services, which it did not review in 2010. These size standards are all receipts based. SBA is retaining the current standards for the remaining industries in NAICS Sector 54. This rule also removes "Map Drafting" as the "exception" to NAICS 541340, Drafting Services. As part of its ongoing comprehensive review of all size standards, SBA has evaluated every receipts based size standard in NAICS Sector 54 as well as the one previously unreviewed size standard in NAICS Sector 81 to determine whether the existing standards should be retained or revised.
