Frequently Asked Questions
What is a WOSB set-aside?
A WOSB (Women-Owned Small Business) set-aside is a federal contract reserved for businesses that are at least 51% owned by women who are U.S. citizens, and whose management and daily business operations are controlled by one or more women. WOSB set-asides are limited to industries where women are underrepresented in federal contracting.
How do I get WOSB certification?
Apply for WOSB certification through certify.sba.gov. Third-party certifiers approved by the SBA can also certify WOSB status. You must demonstrate that a woman (or women) own at least 51% of the business, that a woman controls management and daily operations, and that the business meets small business size standards for its primary NAICS code.

Federal construction contracts (NAICS sector 23) span building construction, heavy civil engineering, and specialty trades.
