SDVOSB vs WOSB / EDWOSB
The SDVOSB and Women-Owned Small Business (WOSB) programs are structurally similar — both are ownership-based, both require SBA certification, and both authorize competitive set-asides and limited sole-source awards. The defining difference is industry scope: an SDVOSB set-aside can be used in any NAICS code, while WOSB and Economically Disadvantaged WOSB (EDWOSB) set-asides are limited to the specific industries where SBA has found women to be underrepresented or substantially underrepresented.
Side by Side
| SDVOSB | WOSB/EDWOSB | |
|---|---|---|
| Qualifying owner | One or more service-disabled veterans | One or more women (EDWOSB adds economic-disadvantage limits) |
| Ownership / control | 51% unconditional, direct ownership and control | 51% unconditional, direct ownership and control |
| Certifying body | SBA VetCert | SBA (WOSB certification via certify.sba.gov) |
| Industry scope of set-asides | Any NAICS code | Only NAICS codes on SBA's designated underrepresented (WOSB) / substantially underrepresented (EDWOSB) list |
| Economic test | None | WOSB: none. EDWOSB: owner must meet economic-disadvantage limits |
| Set-aside authority | Competitive set-asides and sole-source, governmentwide | Competitive set-asides and sole-source within eligible NAICS codes |
| Certification term | Three years, then recertify | Three years, then recertify |
| Key regulation | 13 CFR Part 128; FAR Subpart 19.14 | 13 CFR Part 127; FAR Subpart 19.15 |
Key Differences
- SDVOSB set-asides can be used in any industry; WOSB/EDWOSB set-asides only apply in NAICS codes SBA has designated as underrepresented.
- EDWOSB adds an economic-disadvantage test (net worth, income, asset caps); SDVOSB and base WOSB have no such test.
- Both programs now require SBA certification — self-certification was phased out for WOSB in 2020 and never applied to the current SDVOSB program.
- A firm owned 51% by a service-disabled woman veteran can qualify for both programs and pick the most advantageous designation per opportunity.
Which to Pursue
When SDVOSB fits
SDVOSB is the better fit when the owner is a service-disabled veteran and the work falls outside the WOSB-designated NAICS codes, or when you want a set-aside tool that works in every industry.
When WOSB/EDWOSB fits
WOSB/EDWOSB is the path for women-owned firms, and it can be the stronger play when the firm operates in a designated NAICS code where a WOSB set-aside is available and the firm does not have veteran ownership.
Can You Hold Both?
A service-disabled woman veteran's firm can be certified as both SDVOSB and WOSB/EDWOSB. Holding both lets the firm respond to SDVOSB set-asides anywhere and WOSB set-asides in designated industries, choosing whichever applies to a given solicitation.
Frequently Asked
Can a firm be both SDVOSB and WOSB?
Yes. A small business that is at least 51% owned and controlled by a service-disabled woman veteran can be certified as both an SDVOSB and a WOSB (or EDWOSB), and may compete under either program depending on the solicitation.
Why can't I use a WOSB set-aside on every contract?
WOSB and EDWOSB set-asides are restricted to the NAICS codes SBA has designated as industries where women-owned businesses are underrepresented or substantially underrepresented. SDVOSB set-asides have no such industry restriction.
Do both programs require SBA certification?
Yes. Both SDVOSB and WOSB/EDWOSB require formal SBA certification. WOSB self-certification was eliminated in 2020, and the SDVOSB program has been certification-based under SBA since January 1, 2023.
