Do You Need a J&A for a Phase III SBIR Sole Source? (No — And Here's What You Actually Need.)
Contracting officers often default to a Justification & Approval document for sole-source awards. A Phase III SBIR doesn't require one. The statutory authority is its own justification.
No. A Phase III SBIR award does not require a J&A. The SBIR statute is the sole-source authority. A Determination & Findings (D&F) memorializing that authority is the normal substitute.
I've seen good Phase III awards die because a J&A got drafted, sent up for higher-level review, and came back asking for things that simply don't apply under SBIR authority. The fix is to never let the J&A get drafted in the first place. Bring the statute and the agency's own Phase III guidebook to the very first contracting conversation.
Every time a Phase II awardee starts conversations about a Phase III contract, the same question comes back from the contracting shop: "We'll need a J&A for that, right?" The answer is no — and the cleaner the explanation, the faster the award moves. This is one of the few pieces of SBIR knowledge that can change the timeline of an award by months.
Two different sole-source authorities. Don't mix them up.
Federal contracting has more than one kind of sole source. The two that matter here are:
- FAR Part 6 sole source. The general-purpose framework. It is invoked through FAR 6.302 (only one responsible source, unusual and compelling urgency, etc.) and requires a written Justification & Approval (J&A), which is reviewed at a higher level inside the agency and is subject to FAR 5.301 synopsis after award.
- Phase III SBIR sole source. A separate authority created by Congress in 15 U.S.C. § 638(r) and operationalized in the SBIR/STTR Policy Directive. It does not flow through FAR Part 6. It does not require a J&A. It has its own contract-file logic.
The mistake most contracting officers make is reaching for the FAR Part 6 framework because it's the one they use every week. The Phase III authority lives in a different part of the regulatory stack and behaves differently. When the wrong framework gets invoked, the award starts dragging documentation it never needed.
What the Phase III file actually needs — and doesn't.
The Phase III file is short. It's one of the procedurally cleanest sole-source pathways in the federal system, which is exactly why it's so frustrating when one stalls.
What it does need is a small number of things done right: the authority invoked correctly, and the lineage to the prior work documented appropriately. Short doesn't mean simple. The file is brief precisely because each piece carries weight; omitting any one of them is enough to stop the award.

How to handle a contracting officer who insists on a J&A.
We've sat on the government side of this exact conversation. The CO isn't being difficult; they're managing risk with the only framework they know. A contractor who shows up to argue regulation usually makes them more cautious, not less. What changes the outcome is rarely the document itself. It's whether the person across the table trusts that invoking the Phase III authority makes them safer, not just you faster.
That's a read you make in the moment — how hard to push, when to escalate, who at the agency should be the one to say yes. It's the part that doesn't fit on a checklist, and it's the part we're brought in for.
Why the J&A path is risky even if you "win" the argument to use it.
Even if a contracting officer writes a J&A for a Phase III, doing so attaches the award to a framework with its own failure modes. J&As above certain dollar thresholds need higher-level approval. They can be returned for revision. They are part of the appealable record. Invoking the Phase III authority directly avoids all of that. The cleanest path is also the shortest path.
Do you need a J&A for a Phase III SBIR sole source?
No. A Phase III SBIR award does not require a Justification & Approval (J&A). The Phase III statutory authority under 15 U.S.C. § 638(r) is its own basis for the sole source. A short Determination & Findings (D&F) typically substitutes.
Then why do contracting officers keep writing J&As for Phase III?
Most contracting officers default to FAR Part 6 because that's the framework they use every day. They reach for the J&A out of habit, not because the Phase III pathway requires it. Pointing them to the SBIR statute and the agency's own Phase III training material is usually enough to course-correct.
What documentation does a Phase III award require?
Typically: a Determination & Findings (D&F) invoking the Phase III authority, a DEC statement (derives/extends/completes nexus), market research and price analysis, and standard contract-file items (responsibility determination, representations and certifications). No J&A. No competitive synopsis.
Can a J&A hurt the award even if it's written?
Yes. A J&A invokes the FAR Part 6 framework, which carries its own thresholds and review requirements. If it's poorly drafted or fails higher-level review, the contracting officer may be told to re-do it or to recompete — even though the Phase III authority would have stood on its own.
Have a Phase II that needs a Phase III path?
