Every project runs on its own operating guidance, and that document governs your pay rather than title 5. What follows is the shape of these systems and the specific rules that are publicly documented. For anything that affects a decision, get your project's current operating guide.
I The authority and the catch in it
5 U.S.C. 4703 lets an agency test personnel management practices that depart from ordinary title 5 rules — how people are hired, classified, paid and rewarded.
The catch is in the same statute. Section 4703 mandates evaluation of demonstration projects to assess the effects of their features and outcomes. These are experiments with a reporting requirement, not simply alternative regimes. In AcqDemo's case that produces a standing obligation to maintain a cost-disciplined approach, with continued comparison against the government-wide system to balance salary cost against the value of the position.
A project can outgrow its experimental status: AcqDemo's original demonstration authority was repealed and codified at 10 U.S.C. 1762 on 7 January 2011 by section 872 of the Ike Skelton NDAA for FY2011, converting it into a standing authority. NSPS went the other way. Both outcomes are live possibilities for any project you might join.
II What pay banding actually changes
| General Schedule | Banded system | |
|---|---|---|
| Structure | 15 grades, 10 steps each | A few broadband levels |
| Pay movement | Steps on a fixed waiting period | By contribution assessment |
| Guaranteed increase | Yes — the WIGI | No |
| Speed for a strong performer | Capped by the waiting period | Potentially much faster |
| Promotion between levels | Competitive, grade to grade | Movement between bands |
| Counts toward high-3 | Yes | Yes |
Read the third and fourth rows together, because they are the whole trade. The General Schedule pays you for time: 52, 104 or 156 weeks and an acceptable rating produce a step whether you were exceptional or merely fine. A banded system removes that floor and removes the ceiling with it.
The last row matters more than it looks. Banded pay is still basic pay — it counts toward the high-3 and toward TSP contributions in the ordinary way. The demonstration authority changes how the rate is set, not what it counts as.
III AcqDemo
The Civilian Acquisition Workforce Personnel Demonstration Project covers Department of Defense acquisition workforce positions. It uses broadband levels in place of GS grades and carries its own hiring, pay and promotion flexibilities.
Two structural facts worth knowing. Its authority is now permanent, codified at 10 U.S.C. 1762 since January 2011. And it operates under an explicit cost discipline requirement, comparing itself against the government-wide system to keep salary cost, position value and management benefit in balance — which is a constraint on how generously the bands can be used.
IV Where the detail rules diverge
This is the most concrete advantage of being inside the project, and it is substantial.
AcqDemo participating organisations may effect temporary promotions and details to higher broadband levels than an employee currently holds or previously held without competition, provided the temporary promotion, the detail, or a combination of the two does not exceed one year within a 24-month period, for positions within the demonstration project.
| General Schedule | AcqDemo | |
|---|---|---|
| Noncompetitive limit | 120 days | 1 year in 24 months |
| Lookback | 12 months, aggregated | 24-month window |
| Authority | 5 CFR 335.103 | Project operating guide |
Where the employee's permanent position of record remains in the GS pay plan — for instance a GS employee temporarily promoted into a demo position — the ordinary 5 CFR 335.103 requirement still applies, and competition is required beyond 120 days. The generous allowance follows the position of record, not the assignment. The GS rules are in detail assignments.
V What happened to NSPS
The National Security Personnel System was the largest alternative pay system the federal government has attempted. Congress repealed it.
Section 1113 of the NDAA for Fiscal Year 2010 repealed NSPS and directed the conversion of all NSPS employees back to their previous pay system by 1 January 2012. Employees who had been in AcqDemo before being moved into NSPS were transitioned back to AcqDemo in May 2011.
An alternative pay system is a policy choice, and policy choices reverse. Employees were moved into NSPS without asking, and moved back out again without asking. If you are in a demonstration project, the question “what happens to my pay if this ends” is not hypothetical — it has already happened once, at scale, within recent memory.
VI Better or worse for you
Honestly: it depends on two things, and neither is about the system's design.
Are you a strong performer in the eyes of the people assessing you? Not objectively — in their eyes. A banded system converts that judgement directly into money in a way the General Schedule never does.
How much do you value predictability? The GS step is slow, unexciting and nearly guaranteed. Band movement is faster, larger and conditional.
The same two employees, two systems
A consistently outstanding engineer and a consistently solid one, both mid-career.
Because pay assessment carries this much weight, the rating and assessment record matters more inside a project than outside one.
Two employees, ten years, two systems
The General Schedule pays for time, so both employees track closely. A banded system pays for assessed contribution, so they diverge — upward for one, flat for the other.
Illustrative shapes, not modelled dollars. The point is the spread: banding is not more generous, it is more differentiated.
VII The playbook
| Situation | What to do |
|---|---|
| Offered a position in a demo project | Get the operating guidance. It governs your pay, not title 5. |
| Comparing against a GS offer | Ask which GS grades the broadband level spans, and where in the band you would start. |
| Weighing the trade | No guaranteed annual increase. Ask what an average year actually produces. |
| Strong performer | Banding is likely to your advantage — if your assessors agree you are one. |
| Value predictability | The GS step is slow but nearly guaranteed. Banding removes that floor. |
| Already in AcqDemo | Details and temporary promotions run to a year in 24 months, not 120 days. |
| GS employee detailed into a demo position | Your position of record is still GS. The 120-day rule still applies to you. |
| Worried about repeal | Ask what conversion rules would apply. NSPS is the precedent. |
| Near retirement | Banded pay is basic pay and counts fully toward your high-3, in both directions. |
| Any year | Your contribution assessment is now your pay adjustment. Document accordingly. |
Before you join one
- Request the project's current operating guidance and read the pay chapter.
- Identify which broadband level the position sits in and which GS grades it spans.
- Ask where in the band your starting rate would fall.
- Ask exactly how pay increases are determined and on what cycle.
- Ask what an assessment of average actually produces in dollars.
- Confirm whether any floor exists in a weak year.
- Ask how the project treats details and temporary promotions.
- Confirm your position of record would be in the project, not GS.
- Ask what conversion rules would apply if the project ended.
- Confirm that banded pay counts toward your high-3 and TSP in the normal way.
Frequently asked questions
A time-limited authority under 5 U.S.C. 4703 for an agency to test personnel management practices that differ from the ordinary title 5 rules, including how people are hired, classified, paid and rewarded. The statute requires evaluation: the point is to assess the effects of a project's features and outcomes rather than simply to run a different system indefinitely. Some projects have been made permanent by separate legislation, and at least one large one was repealed by Congress.
Grades and steps are replaced by broad bands. Instead of fifteen grades with ten steps each, a banded system might have four or five broadband levels, each spanning what would be several GS grades. Within a band there are no steps and no scheduled within-grade increases. Your pay moves according to the project's own rules, which are typically tied to an assessment of your contribution rather than to time served. That is the trade in a sentence: the automatic increase is exchanged for a judgement.
The Civilian Acquisition Workforce Personnel Demonstration Project, a Department of Defense project covering acquisition workforce positions. It uses broadband levels rather than GS grades and carries its own hiring, pay and promotion flexibilities. Its original demonstration authority was repealed on January 7, 2011 and codified at 10 U.S.C. 1762 by section 872 of the Ike Skelton National Defense Authorization Act for Fiscal Year 2011, which moved it from a temporary test to a standing authority.
They can be substantially more generous. AcqDemo participating organisations may effect temporary promotions and details to higher broadband levels than an employee currently holds or previously held without competition, provided the temporary promotion, the detail, or a combination of the two does not exceed one year within a 24-month period, for positions within the demonstration project. Compare that with the 120 days that governs the General Schedule. The important qualification is that where the employee's permanent position of record remains in the GS pay plan, the ordinary 5 CFR 335.103 requirement still applies.
Congress repealed it. Section 1113 of the National Defense Authorization Act for Fiscal Year 2010 repealed the National Security Personnel System and directed the conversion of all NSPS employees back to their previous pay system by January 1, 2012. Employees who had been in AcqDemo before being moved into NSPS were transitioned back to AcqDemo in May 2011. It is the clearest illustration that an alternative pay system is a policy choice which can be reversed, and that employees can be moved between systems without having asked to be.
It depends on whether you are a strong performer in the eyes of the people assessing you, and on how much you value predictability. A banded system can move a high contributor upward faster than the General Schedule ever would, because it is not waiting for a 52, 104 or 156-week step interval. The same system offers no floor: a year assessed as average may produce little or no increase, where the General Schedule would have delivered a step regardless. You are trading a guaranteed slow escalator for a faster one that someone else operates.
Basic pay is basic pay. Whatever your rate is under a banded system, it counts toward your FERS high-3 average salary and toward agency Thrift Savings Plan contributions in the ordinary way, because the demonstration authority changes how the rate is set rather than what it counts as. The practical consequence is that the volatility works both ways: strong years compound into the high-3 if they fall in your final three years, and flat years cost you in exactly the same window.
Get the project's own operating guidance, because that document rather than title 5 governs your pay. Ask which broadband level the position sits in and what GS grades it spans, how pay increases are determined and on what cycle, what happens in a year assessed as average, whether there is any floor, and how the project treats details and temporary promotions. Then ask the question people forget: what happens to your pay if the project is ever terminated, because NSPS demonstrates that this is not hypothetical.
