What is a question bank?
A question bank (also called an item bank or Qbank) is a collection of exam questions used to build assessments, such as certification exams or other formal tests. These questions are typically written to align with specific learning objectives and are stored in a centralized system for use in creating different versions of a test.
A question bank can be used for:
- Fixed-form exams, where the same set of questions is given to every test-taker.
- Randomized exams, where questions are selected randomly from the bank to ensure variability and security.
- Adaptive exams, where the system adjusts question difficulty in real time based on a test-taker’s previous answers to accurately gauge their skill level.
Key features of a great question bank
A core feature of a question bank is its alignment with an exam blueprint. The blueprint outlines the exam’s purpose, target audience, and knowledge domains to be tested. It defines the minimum qualifications expected of candidates and distributes questions across various objectives to ensure comprehensive coverage of the subject matter. This structured approach ensures that the exam reflects not just the course content but also real-world skills and job expectations.
Another important feature is the inclusion of diverse question types. A question bank typically includes multiple-choice questions, matching exercises, and scenario-based questions. These are designed to assess different levels of cognition, ranging from basic recall to complex problem-solving. By categorizing questions as recall-based, hybrid (recall and reasoning), or fully reasoning-based, exam developers can create assessments that match the difficulty and depth appropriate for the certification level.
Strict item development standards uphold the quality and consistency of questions in a bank. For example, content writers should avoid using problematic formats, such as “all of the above” or negative phrasing and ensure that distractors (incorrect answer choices) are plausible and don’t give away the correct answer.
Equally important is the principle that a candidate-facing reference must back each question. This means that all questions must be traceable to official documentation, course materials, white papers, or other published sources, ensuring that nothing is based solely on internal or undocumented knowledge. This is a cornerstone of creating legally defensible exams.
Benefits of building a large and diverse question bank
Having a large and diverse question bank allows for the inclusion of various question types, including multiple-choice, matching, and scenario-based items. This enables assessment at various cognitive levels and ensures exams are tailored to the appropriate difficulty level for the intended audience.
It also makes it easier to scale exam delivery, especially when integrated into a test platform that can randomize or rotate questions. This enhances exam security and enables reusability in future exams or different versions of the same test.
Process to create a bank of questions
Typically, the process of building an exam containing a question bank involves multiple stages. The first step is to create a Test Definition Document, which outlines the title and purpose of the exam, the intended audience (entry-level, intermediate, advanced, etc.) and what content is in scope and what is out of bounds. It should also include a clear definition of the minimally qualified candidate (MQC), as well as the fully qualified and unqualified candidates. This helps determine the difficulty level and types of questions that should be included.
Once the test definition is established, the team develops an exam blueprint—the foundation for the question bank. The blueprint defines the
- Topics or content areas to be covered
- Competencies under each topic
- Number of questions per objective
- Question types required (recall, reasoning, or a combination).
Before questions are written, SMEs receive item-writing training that includes question construction rules (e.g., avoiding “all of the above”, avoiding negative phrasing, creating plausible distractors), best practices for grammar, clarity, and logic, and tips on how to create thought-provoking, valid questions that align with the blueprint.
Depending on the content and the experience of the SMEs, it might take around one hour per item. The hardest part is writing good distractors (incorrect answer choices that are still plausible). After questions are written, they go through a collaborative review process. SMEs:
- Validate each question against the blueprint and objectives
- Ensure each question is supported by a documented reference (such as course material, white papers, or product documentation)
- Debate the clarity, accuracy, and difficulty of each item
- Reject or revise questions that are too easy, too hard, or ambiguous
This iterative review ensures that each question is technically sound, fair, and aligned with the intended candidate profile. Once the items are finalized, the team sets the cut score (the minimum passing score) and the duration of the exam.
Challenges when building bank of questions
Creating a high-quality question bank presents several challenges that impact both the efficiency of the process and the credibility of the final exam. One of the primary difficulties is the requirement for tangible, candidate-facing references for every question. These references are essential for maintaining legal defensibility, but finding and documenting them is often a slow and tedious task.
Another major challenge is developing plausible distractors, which are the incorrect options in multiple-choice questions. While it is usually straightforward to write the correct answer, crafting believable and reasonably correct distractors is much harder. Weak or “throwaway” distractors increase the likelihood of guessing correctly, which can undermine the fairness and validity of the exam.
Writing good scenarios also requires striking the right balance between quality and brevity. In most IT exams, candidates are allotted about 90 seconds per question. If a scenario takes too long to read, it cuts into the time available for candidates to think through their answer. The challenge is to make questions concise without oversimplifying them or resorting to overly informal, “chat-speak” language.
Time constraints add another layer of difficulty. SMEs often have busy schedules and are drawn from different parts of the organization, making coordination difficult. Question-writing workshops typically run on tight timelines, sometimes within a week, and can involve long days and extended working hours to meet deadlines. Coordinating with all the SMEs can be challenging and time consuming.
FAQs
What is an exam blueprint?
An exam blueprint is a structured document that outlines:
- Knowledge domains or topics – the subject areas to be tested.
- Learning objectives/Competencies – what candidates should know or be able to do in each domain.
- Weighting and distribution – how many questions will come from each topic or objective, ensuring balanced coverage.
- Question types – whether questions will assess basic recall, applied reasoning, or both.
What is a test blueprint?
A test blueprint is another name for an exam blueprint. It’s a structured framework that outlines exactly how an assessment will be developed, ensuring it’s fair, valid, and aligned with its purpose. It details the following
- Knowledge domains or topics – the subject areas to be tested.
- Learning objectives/Competencies– what candidates should know or be able to do in each domain.
- Weighting and distribution – how many questions will come from each topic or objective, ensuring balanced coverage.
- Question types – whether questions will assess basic recall, applied reasoning, or both.
What are blueprint questions?
Blueprint questions are simply exam or test questions that are mapped directly to a test blueprint. When you create a test blueprint, you define content areas, learning objectives, and weighting for your exam. Every question you write must link to (or be “tagged” with) a specific purpose in that blueprint. This ensures coverage (all topics get their fair share), consistency (questions match the intended difficulty), and validity (the exam measures what it’s supposed to).
What is the function of question bank?
A question bank is a centralized and organized repository of exam questions designed to support the creation of fair, consistent, and secure assessments. Its primary function is to store vetted and approved exam items in one place, making it easier to reuse content, scale exam delivery, and update tests without having to start from scratch.
One of the key roles of a question bank is to ensure coverage and alignment with the exam blueprint. Each question is tagged to a specific domain or learning objective, which guarantees that all required topics are represented in the correct proportions.
A well-designed question bank also supports varied assessment formats. It can deliver fixed-form exams, where every candidate answers the same set of questions, randomized exams, where each candidate receives a unique combination of questions. It can also be used for adaptive exams, where the system adjusts question difficulty in real time based on a test-taker’s previous answers to accurately gauge their skill level.
Beyond storage, the question bank plays a critical role in maintaining question quality and validity. Each item in the bank is reviewed, referenced, and developed in accordance with item-writing standards, so each question is clear, fair, and legally defensible. By rotating or randomizing questions, the bank further protects exam integrity while allowing for ongoing use of well-crafted content.
