What is a set-aside?

Definition in one paragraph

A set-aside is a contracting procedure that limits competition to businesses that meet a specific eligibility category (for example, small business under the NAICS size standard, 8(a) participants, HUBZone, service-disabled veteran-owned, women-owned). It is a competition rule, not a participation trophy and not automatic award.

Why set-asides matter for first wins

Open full-and-open competition can include large incumbents with deep past performance. Set-asides narrow the field when you truly qualify. Bidding a set-aside you do not qualify for wastes time and can create compliance risk — eligibility is binary for the program, not a vibe.

Major types you’ll see on notices

GovGazette maintains hubs for each common type with live open counts. Start here, then open the hub that matches your eligibility:

• Total Small Business — reserved for small under the applicable size standard → /contracts/set-aside/total-small-business
• Partial Small Business — only part of the requirement is set aside → /contracts/set-aside/partial-small-business
• 8(a) competed / sole source — SBA 8(a) program paths → /contracts/set-aside/8a-competed
• HUBZone — geographic program eligibility → /contracts/set-aside/hubzone
• SDVOSB / VOSB — veteran programs → /contracts/set-aside/service-disabled-veteran-owned
• WOSB / EDWOSB — women-owned programs → /contracts/set-aside/women-owned-small-business
• Buy Indian / ISBEE / IEE and other specialized categories — see full index

How to use set-asides without fooling yourself

Three checks before you invest proposal hours:

• Do you meet the program rules today (not “we’re applying next year”)?
• Does the notice’s NAICS size standard still leave you small?
• Can you perform the work with your real capacity and any required certifications?

Official rules live elsewhere

Set-aside mechanics live in the FAR (notably Part 19 and related provisions) and SBA program rules. Our FAR reference library lists official titles for citations you see on solicitations — use them as a map to Acquisition.gov, not as legal advice.
