SBA has established numerical definitions, or "size standards," for all for-profit industries.  Size standards represent the largest size that a business (including its subsidiaries and affiliates) may be to remain classified as a small business concern.  These size standards apply to SBA’s financial assistance and to its other programs, as well as to Federal government procurement programs when there is a benefit available to qualifying as a small business concern.  Also, the Small Business Act states that unless specifically authorized by statute, no Federal department or agency may prescribe a size standard for categorizing a business concern as a small business concern, unless such proposed size standard meets certain criteria and is approved by the Administrator of SBA.
