Platinum Adaptive Design Items
Most exams ask if you know the answer. PAD asks you to build it.
PAD stands for Platinum Adaptive Design. A PAD item is a single exam question in which the candidate is given a customer’s situation and designs the solution themselves, placing components on a live diagram that redraws as they work. Then the scenario moves on, and the next stage is built on the design they just drew, mistakes and all.
First, what is an exam item?
In certification, each question in an exam is called an item. Items come in different types, and the type decides what an exam can actually prove about the person who passes it. Here are the common types, from the simplest to PAD.
Multiple choice
A question with four answers underneath. One is correct.
Can they recognise the answer?Scenario multiple choice
A short story about a customer, then a choice of answers.
Can they apply what they know?Live lab
The candidate carries out a task on real or virtual equipment.
Can they operate the product?PAD item
The candidate designs a solution on a live diagram, across several stages.
Can they design the solution?Think of the driving test
Everyone has met a theory test: what does this sign mean, what is the stopping distance? Nobody thinks passing it means you can drive. That is why there is a practical test, in a real car, on a real road. Most technical qualifications only have the theory test. A PAD item is the closest thing to the practical test for a designer, without needing the car.
Pointing at the right answer isn’t the job
Expert certifications promise that their holders can design solutions. Most of them can’t actually check that.
Recognising isn’t producing
Plenty of people can spot a good design among four options without being able to create one themselves.
Questions get memorised
Question banks leak and circulate online. A memorised answer passes a multiple-choice question as easily as real skill.
Labs are expensive
Hands-on labs test real skill, but they need equipment or computing for every candidate, bookings, and upkeep every time the product changes.
The diagram is the answer sheet
The candidate reads a customer brief, and a diagram of that customer’s world appears on screen. There is no list of finished answers to choose from. They pick components from a palette, place each one where they judge it belongs, and connect them. The diagram redraws around every decision.
The scenario runs across several phases of one customer project. Each phase opens on the diagram exactly as the candidate left it, including anything they got wrong. Nothing is corrected in between.
What “adaptive” means here
- The diagram changes shape to match what the candidate decides.
- Later questions are built on their earlier answers.
- It does not mean the exam gets harder or easier. Every candidate gets the same scenario and the same tasks.
- It does not mean AI. Marking follows fixed rules and gives the same result every time.
Design it. Then live with it.
Read the brief
A realistic customer situation: an ageing setup, a new requirement, a deadline.
Design phase one
Choose components, place them and connect them on the live diagram.
Build on it
The project moves on. Each new phase starts from the candidate’s own design.
Submit once
One submission at the end. The candidate is never told whether they were right.
Like building a house
Put the boiler in the wrong place in week one and nobody says a word. You find out in week three, when the pipes won’t reach. A PAD item never tells the candidate they’ve put the boiler in the wrong place. It just carries on building the house.
What PAD items give an exam programme
Candidates design, they don’t pick
The candidate builds an answer instead of choosing one. There are so many possible designs that guessing doesn’t work, yet each one can still be marked exactly.
Measures design skill, not recallDecisions carry forward
A shortcut taken early shows up as a problem later, just as it would on a real project. Separate questions can’t test that, because each one starts afresh.
Tests judgement under consequenceOne mistake costs once
Where a later answer depends on an earlier choice, it’s marked against what the candidate actually built. An early slip isn’t punished again in every later phase.
Fair marking of later tasksNever told if they were right
No ticks, no crosses, no score on screen. Sitting the item again teaches nothing about the answers, and a leaked screenshot shows nothing about whether a design was any good.
No feedback to exploitVariants defeat memorisation
A variant keeps the same customer but changes what they need, so the right answer in one version becomes the most tempting wrong answer in the other.
A bigger item pool for less effortReword and translate freely
The wording on screen can change for a new product name, market or language without redoing the marking scheme.
Lower cost over the life of the examA readable record of every attempt
Each submission records every decision and the exact wording the candidate saw. It can be re-marked later, quoted in an appeal, or analysed across a group of candidates.
Defensible results and better examsRuns as one web page
No lab, no installation, no per-candidate computing. It appears as the next question inside the exam platform the candidate is already using.
Lab-level rigour at web-page costHow PAD compares
PAD items sit between a written scenario question and a full live lab. They bring much of the assessment value of a lab at close to the cost of a written question.
| Multiple choice | Scenario multiple choice | Live lab | PAD item | |
|---|---|---|---|---|
| What it measures | Recall | Applied recall | Hands-on operation | Analysis, design and judgement |
| The candidate produces | A choice | A choice | A configured system | A design |
| Can guessing work? | Yes | Yes | No | No |
| Decisions carry forward | No | Rarely | Yes | Yes, by design |
| Equipment needed | None | None | Computing for every candidate | None: one web page |
| Cost per attempt | Very low | Very low | High | Very low |
| Marking | Automatic | Automatic | Scripted checks, often fragile | Automatic and exact |
| Cost of a new version | Low | Low | Very high | Low |
| Looks like the job | No | Somewhat | Yes | Yes |
PAD items assess design, not hands-on operation. They complement live labs rather than replace them.
Pass or fail, with the detail behind it
A PAD item is marked pass or fail as a whole, because a design with a broken phase isn’t a working design. Alongside the result, it reports how the candidate did in each phase.
- Exact and repeatable. The same submission always gets the same mark, so any attempt can be re-marked later if the marking scheme is corrected.
- Every wrong answer explained. Each incorrect option has a written reason it fails in this scenario, recorded before any candidate sits the item.
- Insight for the exam programme. Per-phase results show which tasks are hardest and which wrong answers attract the strongest candidates.
Built so every candidate can show what they know
Works fully from the keyboard
Every placement can be made without a mouse. Drag-and-drop is an option, never a requirement.
Screen reader support
Every change to the diagram is announced to assistive technology: what was placed, and where.
Colour is never the only signal
Every state on the diagram also has a shape, outline or text cue, so colour vision makes no difference.
Made for test-centre screens
Select a component once, then click every place it belongs. No awkward dragging across a large diagram on a small screen.
Protecting the item, honestly described
Opens only for a real exam
The item checks with the exam system before it shows anything. If it can’t confirm a valid sitting, it stays closed.
Nothing reveals the answers
No verdicts and no feedback on screen. Colours mean “answered” or “you can act here”, never “correct”.
Copying is discouraged
Copying and printing are refused, and attempts to capture the screen are detected and recorded.
What we don’t claim: no web page can stop someone photographing a screen. Screen capture is detected and deterred, not prevented. Full prevention needs a locked-down exam browser, which is a feature of the delivery platform.
Who PAD items are for
Expert and master-level certifications
Where a credential says its holder can design something, and multiple choice alone can’t back that up.
Programmes raising their standards
When pass rates look too high, questions are leaking, or an accreditation body asks what the exam really measures.
Where a live lab costs too much
Design can be assessed without equipment, bookings or computing for every candidate.
Any subject with a diagram
Wherever the right answer is “which parts, placed where, connected how”: infrastructure, networking, cloud, security and beyond.
