Size Protest (SP)

A Size Protest is a formal challenge to a company’s claimed small business status for a specific procurement. It is used when a party believes the awardee or offeror does not actually qualify as small under the assigned NAICS code and size standard.

What Is a Size Protest?

In government contracting, a Size Protest is the process used to question whether a business is eligible to compete as a small business for a particular opportunity.

It is important because small business set-asides are limited to firms that truly meet the applicable size requirements.

Key Characteristics

Formal challenge to small business status

Tied to a specific procurement

Usually based on the assigned NAICS code and size standard

Can affect eligibility for award

Reviewed through the SBA size determination process

How It Works in Government Contracting

A Size Protest usually happens after bids or proposals are submitted and often after the apparent successful offeror is identified. An eligible party files the protest, and the matter is reviewed to determine whether the challenged company qualifies as small for that procurement.

It is used by offerors, contracting officers, SBA officials, and legal or contracts teams. In practice, the review may examine ownership, affiliation, receipts, employee count, and other factors that affect size status.

If the company is found other than small, it may lose eligibility for that set-aside award.

Regulatory Framework

Size Protests are part of the federal small business eligibility framework. Their outcome depends on the assigned NAICS code, the applicable size standard, and SBA rules on size and affiliation.

The protest must usually follow specific timing and filing rules to be considered.

Why It Matters for Contractors

A Size Protest matters because it can directly affect whether a company can win or keep a small business set-aside award. It can also delay award decisions and create business risk for the challenged firm.

It also matters strategically because contractors need to understand their own size status, affiliation risks, and protest exposure before pursuing set-aside work.

Common Misconceptions

It challenges small business eligibility, not technical merit.

Any company can file a Size Protest at any time.

There are usually rules about who may file and when it must be filed.

A company’s size is the same for every procurement.

Size status can depend on the NAICS code and size standard assigned to the specific opportunity.
