Understanding set-aside programs: 8(a), HUBZone, WOSB, VOSB and SDVOSB

A set-aside is a contract, or part of one, that an agency reserves for a particular group of businesses. The best-known set-asides are for small businesses generally, and several are reserved for small businesses that meet additional criteria through programs run by the Small Business Administration (SBA). This guide explains how set-asides work and gives a plain summary of each program. Eligibility rules are detailed and change over time, so treat this as orientation and confirm everything on the official program pages before you apply.

How set-asides work

The Federal Acquisition Regulation directs contracting officers to set aside acquisitions for small businesses when there is a reasonable expectation of receiving offers from at least two responsible small businesses at fair market prices. This is widely called the rule of two. Contracting officers also consider the socioeconomic programs below, and may set aside for a program's participants, or in some cases award a sole-source contract, when that program's conditions are met.

Three points apply to every set-aside:

• Size is measured against the solicitation's NAICS code. You must be small under the size standard for the NAICS code assigned to that acquisition, whatever program you are in.
• Limitations on subcontracting apply. When you win a set-aside, you must perform a required share of the work yourself or with similarly situated businesses. The rules differ between services, supplies and construction.
• Status is verified. For the programs below, you generally need an SBA certification recorded before you can be awarded a set-aside under that program, and your SAM.gov registration must be accurate.

8(a) Business Development program

The 8(a) program helps small businesses owned and controlled by socially and economically disadvantaged individuals. Participants receive business development support and can compete for 8(a) set-asides and, within limits, receive sole-source awards.

In summary, the business must be small, at least 51 percent unconditionally owned and controlled by one or more socially and economically disadvantaged individuals who are U.S. citizens, and show good character and potential for success. SBA's rules define social and economic disadvantage, including net worth, income and asset thresholds. Participation lasts a maximum of nine years, and a business can participate only once.

The 8(a) program has been subject to legal and policy changes in recent years, including to how social disadvantage is established. Read SBA's current program page before you plan around it.

HUBZone program

The Historically Underutilized Business Zone (HUBZone) program directs contracts to businesses in economically distressed areas. To be certified, the business must be small, owned and controlled at least 51 percent by U.S. citizens (or by certain eligible entities such as Community Development Corporations, agricultural cooperatives or Native American organizations), have its principal office in a HUBZone, and have at least 35 percent of its employees living in a HUBZone.

HUBZone boundaries change over time. SBA publishes a map you can search by address. Certified firms can compete for HUBZone set-asides and receive a price evaluation preference in some full and open competitions, and must recertify periodically.

Women-Owned Small Business (WOSB) program

The WOSB Federal Contract program lets agencies set aside contracts for women-owned small businesses in industries where women are underrepresented. To qualify, the business must be small and at least 51 percent owned and controlled by one or more women who are U.S. citizens, and women must manage day-to-day operations and make long-term decisions.

The Economically Disadvantaged Women-Owned Small Business (EDWOSB) designation adds economic disadvantage thresholds and opens additional set-asides. WOSB and EDWOSB set-asides can only be used for NAICS codes on SBA's list of eligible industries. Since 2020, self-certification is no longer accepted for these set-asides: you must be certified by SBA or an approved third-party certifier.

Veteran-Owned and Service-Disabled Veteran-Owned Small Business (VOSB and SDVOSB)

SBA's Veteran Small Business Certification program, often called VetCert, certifies veteran-owned small businesses and service-disabled veteran-owned small businesses. Responsibility for certification moved from the Department of Veterans Affairs to SBA on January 1, 2023.

In summary, the business must be small and at least 51 percent owned and controlled by one or more veterans (for VOSB) or service-disabled veterans (for SDVOSB), who manage day-to-day operations. SDVOSB set-asides and sole-source awards are available across the government, and self-certification for them has ended, so certification is required. VOSB set-asides are primarily used by the Department of Veterans Affairs under its own authority.

Choosing which programs to pursue

Certification takes time and documentation, so be deliberate:

1. Confirm eligibility honestly. Read the full eligibility rules and gather the documents that prove each point. If you are unsure, talk to an APEX Accelerator or your local Small Business Development Center before applying.
2. Look at demand. Search past awards on USAspending.gov and current opportunities on SAM.gov for your NAICS codes, filtered by set-aside type. A certification is most valuable where agencies actually use it for your kind of work.
3. Plan the paperwork. Applications typically ask for ownership and formation documents, tax returns, resumes and, for HUBZone, employee residency evidence. Keep them organized and current.
4. Keep it current. Certifications carry ongoing obligations, including recertification and updates when ownership, size or location change.

A certification is not a contract. It makes you eligible to compete for certain work; you still need capabilities, past performance and a strong offer.

How ONE VIEW Launchpad helps

The Certifications module describes each of these programs with links to the official pages and a checklist of the evidence SBA typically asks for. You can track your own status as not started, preparing, submitted or approved, and keep supporting documents in the document vault. ONE VIEW Launchpad never tells you that you are eligible or certified. Only SBA, or an approved certifier where the rules allow, can make that determination.
