FAR 15.101-3—Tiered evaluation of small business offers.
Plain-English Summary
FAR 15.101-3 is a narrow but important restriction on how agencies may evaluate offers for multiple-award contracts when small businesses are involved. It addresses the use of tiered or “cascading” evaluation methods, as described in 13 CFR 125.2, and states that an agency may not use that approach unless it has specific statutory authority to do so. In practice, this means contracting officers and acquisition planners cannot assume they may rank or evaluate offers in a way that gives one tier of offerors priority over another simply because the procurement is a multiple-award vehicle. The rule exists to keep evaluation methods aligned with the Small Business Act and SBA regulations, and to prevent agencies from using evaluation structures that could improperly disadvantage small business participation. For contractors, especially small businesses, this section matters because it limits the government’s ability to design competitions that funnel awards away from certain offerors based on tiered preference structures. For agencies, it is a compliance checkpoint in acquisition planning, solicitation drafting, and source selection design.
Key Rules
No tiered evaluation by default
An agency may not create a tiered or cascading evaluation of offers for a multiple-award contract. The prohibition applies to the evaluation structure itself, not just to award decisions, so the solicitation cannot be designed to rank offers in a cascading sequence unless an exception applies.
Cascading defined by SBA rules
The term “tiered” or “cascading” evaluation is tied to the concept described in 13 CFR 125.2. That cross-reference matters because agencies must look to the SBA’s definition and framework when determining whether a proposed evaluation method is prohibited.
Statutory authority is required
An agency may use a tiered evaluation only if it has express statutory authority. Without that authority, the agency cannot rely on internal policy, convenience, or general acquisition discretion to justify the approach.
Applies to multiple-award contracts
This restriction is specifically directed at multiple-award contracts. It does not broadly prohibit all evaluation preferences or all small business set-aside procedures, but it does limit one particular evaluation method in the multiple-award context.
Responsibilities
Agency
Must ensure acquisition strategies and solicitation terms do not use tiered or cascading evaluation methods for multiple-award contracts unless a statute specifically authorizes that structure.
Contracting Officer
Must review the planned evaluation scheme for compliance before issuing the solicitation, and must avoid including cascading evaluation language or procedures unless statutory authority has been confirmed.
Source Selection Team
Must evaluate offers using the solicitation’s lawful evaluation criteria and may not apply a tiered ranking structure that is prohibited by this section.
Small Business Offerors
Should review solicitations for tiered evaluation language and, if present without clear statutory authority, consider raising the issue through questions, protests, or other available remedies.
Legal/Policy Advisors
Should verify whether any claimed exception is supported by actual statutory authority and ensure the acquisition plan and solicitation align with FAR and SBA requirements.
Practical Implications
This section is mainly a solicitation-design rule: if the evaluation method is unlawful, the competition can be vulnerable to protest before award.
Contracting officers should check both FAR and SBA rules early in acquisition planning, because a prohibited cascading structure is easier to prevent than to fix after solicitation release.
A common pitfall is assuming that because a multiple-award vehicle is being used, the agency may create tiers to favor certain offerors; this section says not unless a statute clearly allows it.
Small businesses should pay close attention to evaluation language that appears to rank or sequence offerors by category, because that may signal an improper tiered approach.
Agencies should document the legal basis for any nonstandard evaluation method, since the absence of statutory authority is the key compliance risk under this section.
Official Regulatory Text
An agency shall not create a tiered (or "cascading") evaluation of offers, as described in 13 CFR 125.2 , for multiple-award contracts unless an agency has statutory authority.
