PSK I preparation: mock exams under real conditions
Professional Scrum with KanbanAdvanced
Scrum.org's PSK I (Professional Scrum with Kanban™) certification validates your knowledge of using Kanban within a Scrum Team. The aim is to support the creation and delivery of value, without compromising the principles of Scrum or those of Kanban. It addresses Scrum Masters, Developers and Product Owners who want to improve how work flows through their team.
The exam covers three sets.
- The combination of Scrum and Kanban, and how the two reinforce each other.
- The Kanban practices from the Kanban Guide for Scrum Teams: visualising the workflow, limiting work in progress, active management, Definition of Workflow.
- The associated flow metrics: Cycle Time, Work Item Age, Throughput, Little's law.
The official exam has 45 multiple-choice questions, to answer in 60 minutes. The minimum score is 85 %.
On ScrumKata, preparing for the PSK I rests on five things.
- Questions matched to the difficulty of the exam.
- Original mock exams and revision questions.
- Timed tests, in the official format.
- Detailed tracking of your progress.
- An explanation for every answer, with the section it draws on.

Sample PSK I questions
Here are 3 free questions with their full explanation, exactly what you will find in the practice modes.
A Scrum Team proposes dropping Sprint Planning: its board always shows what to do next, and the Product Backlog is ordered. Which response is soundest?
- The proposal is acceptable as long as Throughput stays stable
- Sprint Planning can be replaced by a weekly board review
- The board says what comes next, not why the Sprint is valuable; the Sprint Goal would be lost with the event
- The proposal is acceptable if the team keeps the Daily Scrum and the Review
The board says what comes next, never why the Sprint is valuable. Sprint Planning produces the Sprint Goal, which exists precisely to support trade-offs during the Sprint when circumstances change. Without it, the team runs a queue in order with no shared intent.

Who is accountable for creating and adapting the Definition of Workflow?
- To the relevant roles on the Scrum Team, depending on the scope of the workflow
- To the Scrum Master, as guardian of the process
- To the organization, to ensure consistency across teams
- Always to the entire Scrum Team, regardless of scope
It is the accountability of the relevant roles on the Scrum Team, as described in the Scrum Guide. Scope determines who decides: a workflow limited to the Sprint Backlog belongs to the Developers, while a workflow beyond that belongs to the whole Scrum Team. No one outside tells the team how to define its workflow.
Kanban Guide for Scrum Teams — Definition of Workflow
Three Sprints after adopting Kanban, a Scrum Team has introduced a weekly 45-minute meeting dedicated to analyzing its flow metrics. The Sprint Retrospective has shrunk to a round of feelings. Which reading is most accurate?
- The problem is that the meeting is weekly rather than daily
- It is acceptable as long as the Retrospective keeps its maximum timebox
- Metric inspection belongs in the Sprint Retrospective; the extra meeting hollowed it out
- It is good practice; metric analysis needs dedicated time more frequent than the Sprint
Kanban requires no additional events. Here the new meeting has hollowed out the Retrospective, when metric inspection belonged there in the first place, alongside adapting the Definition of Workflow. The problem is not the Retrospective's length but the relocation of its content.

Where these questions come from
Every question is written from the official guides, and carries the section it draws on. We publish no dumps: practising on leaked questions teaches you to recognise a wording, not to reason, and on exam day the slightest rephrasing leaves you stuck. The explanation says why the right answer is right, and why the others are not.
Frequently asked questions about the PSK I
How do you prepare for the PSK I?
The PSK I assesses using Kanban inside Scrum: Definition of Workflow, limiting work in progress, flow metrics and Little's law. The method that works has four steps: read the official guide from end to end, sit one mock exam to find out where you actually stand, work first on the topics sitting below the 85% threshold, then sit timed mock exams until you clear that threshold consistently. Revising without measuring is working blind.
How do I know I am ready for the PSK I?
By your readiness score: the average of your last five PSK I mock exams, set against the official 85% threshold. Only mock exams count, never Practice mode, since it shows the answer as you go. ScrumKata also breaks the gap down topic by topic, ranked by its effect on the final score, so you know what to work on and not only where you stand.
What is the format of the PSK I exam?
45 questions in 60 minutes, and 85% correct answers to pass. The Mock exam mode on ScrumKata reproduces that format exactly: the same number of questions, the same timer, and no feedback before the end.
Where can I find PSK I questions to practise on?
ScrumKata has 300 original PSK I questions, spread across topics according to each topic's official weight in the exam, and across difficulty levels. Every question comes with a detailed explanation and a reference to the guide it draws on. Some are free, with no card required.
Is one PSK I mock exam enough to prepare?
A mock exam measures, it does not teach. It gives you a score and, if it is well built, the list of your weak topics. What changes the outcome is what you do next: revisit the questions you missed, understand why the right answer is right, and check on the next pass that the idea has stuck. A practice test on its own tells you where you stand, not how to improve.
Are the PSK I questions on ScrumKata the real exam questions?
No, and that is deliberate. We publish no dumps. Every question is written from the official guides, with a reference to the section it draws on. Practising on leaked questions teaches you to recognise a wording, not to reason, and on exam day the slightest rephrasing leaves you stuck.
How much does the PSK I exam cost?
At the time of writing, Scrum.org charges around $200 per PSK I attempt, with no free retake if you fail. Check the current figure on scrum.org, as these prices change. ScrumKata does not sell the certification: you pay Scrum.org directly to sit the exam.
How long does it take to prepare for the PSK I?
That depends on where you start far more than on a number of hours. With daily Scrum practice, a few weeks of focused revision is often enough. Without field experience, expect longer. The right marker is not elapsed time but the point where your mock exams clear 85% consistently.
