WOSB & EDWOSB Set-Aside
Contract Opportunities
The federal government has a statutory 5% WOSB goal — and consistently misses it. That gap is your opportunity. Mindy maps WOSB and EDWOSB eligibility to the specific NAICS codes where the set-aside applies, so you only see work your certification actually unlocks.

Who Qualifies for WOSB and EDWOSB
WOSB and EDWOSB are two tracks of the same program. Both require women ownership and control; EDWOSB adds an economic-disadvantage threshold that expands the eligible NAICS list.
WOSB
- →51%+ owned and controlled by U.S. citizen women
- →Day-to-day management by one or more women
- →Small business size standards for your NAICS
- →Operates in a WOSB-eligible NAICS code
- →SBA certification via certify.SBA.gov or approved third-party certifier
EDWOSB (broader NAICS access)
- →Everything required for WOSB, plus:
- →Owner personal net worth under $850K
- →Average AGI under $400K (last 3 years)
- →Personal assets under $6.5M
- →Access to a substantially broader list of eligible NAICS codes

Where WOSB Opportunities Actually Live
WOSB and EDWOSB opportunities show up across the standard federal channels — but the NAICS restriction means you have to filter carefully. Here's where to look:
SAM.gov WOSB / EDWOSB set-asides
Filter SAM.gov by “WOSB Set-Aside” or “EDWOSB Set-Aside.” Sole-source variants exist for both. The set-aside type field on each opportunity tells you exactly which track applies.
Full-and-open with small business consideration
On full-and-open contracts, WOSB certification helps you count toward an agency's small-business and women-owned goals — making you a preferred small-business teaming partner for large primes building bids.
Agency forecasts
Most agency forecasts identify anticipated WOSB or EDWOSB set-aside designations 6–18 months out. Use forecasts to start agency conversations early — before the RFP locks the requirement.
Subcontracting opportunities
Large primes on contracts over $750K must submit subcontracting plans with small-business goals — including women-owned categories. Certified WOSBs are sought-after teaming partners.
Top Agencies Awarding WOSB Contracts
Because the federal government chronically misses the 5% WOSB goal, most agencies are actively trying to award more — but a handful drive the bulk of historical WOSB spend:
Department of Defense
Largest absolute WOSB dollar volume. Army, Navy, and Air Force run WOSB set-asides across professional services, IT, and base operations.
Department of Homeland Security
Active WOSB usage in CBP, FEMA, and TSA — especially for IT services, training, and administrative support.
General Services Administration
WOSB and EDWOSB Schedule task orders are a consistent pipeline; GSA actively promotes the program.
Department of Health and Human Services
NIH, CDC, and CMS regularly use WOSB set-asides for research support, IT, and consulting.
Department of Veterans Affairs
WOSB applies after Veterans First priority is met — significant volume for women-owned firms that aren't also veteran-owned.
How to Win WOSB Contracts: 6 Tactics That Actually Work
1. Certify as EDWOSB if you qualify
EDWOSB unlocks a substantially broader list of eligible NAICS codes than WOSB alone. If you meet the economic-disadvantage thresholds, certify at the EDWOSB level — you still keep WOSB eligibility and add the EDWOSB-only pool on top.
2. Confirm your NAICS is eligible
The single biggest WOSB-strategy mistake is assuming the set-aside applies to your work when your primary NAICS isn't on the eligible list. Check the current SBA list before counting on the set-aside — and consider adding eligible NAICS codes if you can legitimately perform that work.
3. Talk to OSDBU about the 5% gap
Every agency has a scorecard. Ask the OSDBU where they stand against the 5% WOSB goal. If they're behind, they will actively help you find work that closes the gap — including sole-source consideration in NAICS where the agency has weak performance.
4. Position as a teaming partner
Large primes on $750K+ contracts must submit subcontracting plans with women-owned goals. Certified WOSBs are sought-after teaming partners — especially on contracts where the prime is below their WOSB subcontracting commitments.
5. Stack with other certifications
EDWOSB + 8(a) is common because the economic-disadvantage thresholds overlap. WOSB + HUBZone or WOSB + SDVOSB stack cleanly and expand your eligible pipeline well beyond what any single certification opens up.
6. Track WOSB recompetes
When a WOSB incumbent contract is expiring, the recompete will almost always be re-set aside as WOSB or EDWOSB. Mindy flags these 12 months in advance — incumbent name and award value included so you can position before the solicitation drops.

WOSB Frequently Asked Questions
What's the difference between WOSB and EDWOSB?+
WOSB (Women-Owned Small Business) is the general certification — 51%+ owned and controlled by U.S. citizen women. EDWOSB (Economically Disadvantaged WOSB) adds economic-disadvantage thresholds on top: personal net worth under $850K, adjusted gross income under $400K average, and personal assets under $6.5M. The practical impact is that the EDWOSB-eligible NAICS list is broader than the WOSB-only list. If you qualify economically, certify as EDWOSB — you get access to both the WOSB and EDWOSB set-aside pools.
Why does WOSB only apply in certain NAICS codes?+
The WOSB and EDWOSB programs are restricted to NAICS codes where SBA determined women-owned businesses are underrepresented or substantially underrepresented in federal contracting. The list is maintained by SBA and updated periodically based on disparity studies. If your primary NAICS isn't on the eligible list, the WOSB set-aside doesn't apply to that work — even if you're certified. Check your NAICS against the current eligible list at sba.gov before counting on the set-aside.
Do I still need to be SBA-certified, or can I self-certify?+
You must be certified. SBA eliminated self-certification for WOSB and EDWOSB effective October 2020. You can certify directly through certify.SBA.gov (free), or through an SBA-approved third-party certifier like WBENC, the National Women Business Owners Corporation, or El Paso Hispanic Chamber of Commerce (which may charge a fee). Either path gets you in the SBA database; both are equally valid for bidding on WOSB set-asides.
Can WOSB firms win sole-source contracts?+
Yes, but with conditions. WOSB and EDWOSB sole-source authority goes up to $4.5M for services and $8M for manufacturing — same thresholds as 8(a), HUBZone, and SDVOSB. The CO can sole-source to a WOSB or EDWOSB in the eligible NAICS codes when the requirement is below the threshold. WOSB sole-sources are less common than 8(a) sole-sources but do happen, especially at agencies actively pushing to meet the 5% federal-wide WOSB goal.
Does the federal government meet its WOSB goal?+
Historically, no — the 5% federal-wide WOSB goal has been chronically underperformed across most years. Like HUBZone, this gap is your opportunity: OSDBU offices and contracting officers are actively looking for qualified WOSBs to award work to. The shortfall means a certified WOSB with strong capability briefings can often find an agency that's motivated to award.
How does EDWOSB compare to 8(a) for women-owned firms?+
They can overlap. EDWOSB and 8(a) both have economic-disadvantage thresholds, and a woman-owned firm meeting both can certify under both simultaneously. The differences: 8(a) has a nine-year clock and adds the development-program structure; EDWOSB is permanent (as long as you continue to qualify) but restricted to specific NAICS codes. Most successful women-owned 8(a) firms maintain EDWOSB certification too so they don't lose access to WOSB set-asides when they graduate from 8(a).
What happens if my company outgrows the WOSB size standard?+
You lose WOSB eligibility for future opportunities, but you keep contracts you already won. Each NAICS code has its own size standard (revenue or employee count), so it's possible to outgrow WOSB in one NAICS while remaining eligible in another. If you're close to a threshold, work with your primary NAICS carefully — sometimes a slightly different code with a higher size standard preserves eligibility for longer.
