    FAR 19.813Protesting an 8(a) participant's eligibility or size status.

    Plain-English Summary

    FAR 19.813 addresses who may, and may not, challenge the eligibility or size status of an 8(a) participant in the context of 8(a) procurements. It covers four related topics: challenges to an 8(a) participant’s eligibility for a sole-source or competitive 8(a) requirement, protests of the size status of an 8(a) participant nominated for a sole-source 8(a) contract, protests of the size status of the apparent successful offeror in a competitive 8(a) award, and the procedures that apply to protests of competitive 8(a) awards. The section exists to protect the integrity and efficiency of the SBA 8(a) program while still allowing limited size-status review in competitive awards. In practice, it means most eligibility disputes are barred from protest channels, sole-source nominees are insulated from size protests, but competitive award size status can be protested by only a narrow set of parties. It also directs users to the SBA regulations at 13 CFR 124.517 and 13 CFR 121.1001, and to FAR 19.302 for the protest process.

    Key Rules

    Eligibility cannot be protested

    An 8(a) participant’s eligibility for a sole-source or competitive 8(a) requirement may not be challenged by another 8(a) participant or any other party, either before SBA or in any administrative protest forum. This rule blocks bid protests or similar challenges to whether a firm belongs in the 8(a) program for the specific procurement.

    No size protest for sole source

    The size status of an 8(a) participant nominated for a sole-source 8(a) contract may not be protested by another 8(a) participant or any other party. Once SBA and the contracting activity are considering a sole-source 8(a) award, size challenges to the nominated firm are not permitted under this section.

    Limited size protests for competitive awards

    For competitive 8(a) awards, the apparent successful offeror’s size status may be protested, but only by specified parties. The protest right is narrower than in many other procurements and is limited to eligible offerors, the contracting officer, and certain SBA officials.

    Who may file a size protest

    A size status protest for a competitive 8(a) award may be filed only by: (1) any offeror not eliminated for reasons unrelated to size, (2) the contracting officer, or (3) the SBA District Director in the district serving the contracting activity or the apparent successful offeror, or the Associate Administrator for Business Development. Parties outside this list lack standing under this section.

    Use FAR 19.302 procedures

    Protests of competitive 8(a) awards must follow the procedures in FAR 19.302. This means the protest timing, handling, and referral process are governed by the general size-protest framework, supplemented by the SBA regulations cited in 13 CFR 121.1001.

    Responsibilities

    Contracting Officer

    Must recognize that eligibility challenges to 8(a) participants are barred under this section, and must handle competitive 8(a) award protests under FAR 19.302. The contracting officer may also initiate a size status protest for a competitive 8(a) award when appropriate.

    8(a) Participant

    Must understand that its eligibility for a sole-source or competitive 8(a) requirement cannot be challenged through a protest by another 8(a) participant or other party. If selected as the apparent successful offeror in a competitive 8(a) award, its size status may still be subject to a limited protest by authorized parties.

    Other Offerors

    May file a size status protest only if they are offerors not eliminated for reasons unrelated to size in a competitive 8(a) procurement. They may not protest 8(a) eligibility, and they may not protest the size status of a sole-source 8(a) nominee.

    SBA District Director / Associate Administrator for Business Development

    May file a size status protest of the apparent successful offeror in a competitive 8(a) award, subject to the geographic and organizational limits stated in the rule. These SBA officials serve as authorized protest initiators for competitive 8(a) size determinations.

    SBA

    Must apply the governing SBA regulations referenced by this section, including 13 CFR 124.517 and 13 CFR 121.1001, when evaluating eligibility or size-related issues connected to 8(a) procurements.

    Practical Implications

    1

    Most disputes over whether a firm belongs in the 8(a) program for a particular procurement are not protestable, so parties should not waste time filing eligibility challenges in bid protest forums.

    2

    For sole-source 8(a) awards, size status of the nominated firm is effectively shielded from protest, which reduces delay but also means competitors have very limited recourse.

    3

    In competitive 8(a) awards, size protests are allowed only from a narrow group, so contractors should confirm they have standing before filing or responding.

    4

    Contracting officers should be careful to route competitive 8(a) size protests through the FAR 19.302 process and coordinate with SBA as required.

    5

    A common pitfall is confusing an 8(a) eligibility issue with a size-status issue; this section treats them differently and gives much broader protection to eligibility determinations than to competitive-award size status.
