The Women-Owned Small Business program, authorized in the Small Business Act and run by the Small Business Administration, reserves certain federal contracts for firms at least 51 percent owned and controlled by women, in industries where women are substantially underrepresented among business owners. Agencies aim 5 percent of prime contracting dollars at women-owned small businesses — a goal the government first met in fiscal 2015 and has met repeatedly since, per SBA scorecard data, with women-owned small-business prime awards running above $25 billion in recent years. Since a 2020-21 rule change completed a congressional mandate from the 2015 defense-authorization act, self-certification is gone: every firm seeking a WOSB set-aside must be certified, by the SBA directly or through approved third-party certifiers.
How certification works
Two paths, one standard. The SBA's free certification portal certifies directly; four approved third parties — among them the Women's Business Enterprise National Council and the National Women Business Owners Corporation, plus the U.S. Women's Chamber of Commerce historically — certify under their own processes for a fee. Both apply the same test: unconditional at least 51 percent ownership by U.S. citizen women, women controlling management and daily operations, and the highest officer position held by a woman, with the firm small under SBA size standards for its primary industry code. Certification lasts three years with annual attestations. Firms may additionally seek the economically disadvantaged women-owned small-business tier — EDWOSB — by meeting financial thresholds, which opens a further set of sole-source and set-aside contracts.
What the certification unlocks
Set-asides in eligible industries — the SBA maintains the list of qualifying North American Industry Classification System codes where women are underrepresented, updated periodically — and, since a 2012 rulemaking upheld in litigation, sole-source awards up to statutory ceilings in defined circumstances. The practical value concentrates where contracting officers actively use the program: agencies vary widely in WOSB award shares, and the SBA's scorecards publish the dispersion. The compliance side matters equally: size protests, ownership-verification in audits, and the SBA's examinations of third-party certifiers have produced decertifications, and a set-aside won while ineligible converts into a False Claims Act problem, not a paperwork problem.
The honest ledger on program effects
Programs like WOSB sit inside a contested evidence base. Federal contract dollars to women-owned firms have risen since the program gained sole-source authority; whether certification requirements raised barriers for micro-firms that self-certified before is debated in trade commentary, and the SBA's own reports show most WOSB dollars concentrating in a modest number of firms, the pattern that recurs across every socioeconomic contracting program. What is not contested: the certification is now a hard prerequisite, the eligible-industry list is narrower than the whole procurement universe, and the firms that win treat recertification, code eligibility, and joint-venture rules as standing compliance work under the SBA's mentor-protege framework.
FAQ
What is WOSB certification?
SBA program certification that a firm is at least 51 percent owned and controlled by U.S. women citizens, required since 2021 for women-owned small-business set-asides and valid for three years.
Can a woman-owned firm self-certify for set-asides?
No — self-certification ended in 2021; firms certify through the SBA portal or an approved third-party certifier, though registration in the system remains free.
What is EDWOSB?
The economically disadvantaged tier of the program, adding financial-eligibility thresholds and opening additional sole-source and set-aside opportunities.
