Exam registration pages and study guides are full of jargon. This glossary explains the terms in plain language, in alphabetical order. Definitions are kept vendor-neutral; where vendors differ, the entry says so, and the vendor’s own exam page is the authority for the exam you plan to take.
A
Accommodation
An adjustment to the testing conditions, such as extra time or an assistive device, that you request from the vendor or testing provider before exam day. Requests usually need to be made in advance and may need supporting documentation.
Adaptive testing
A format where the questions you see depend on how you answered earlier ones. Many IT exams are fixed-form instead, so check the vendor’s exam page rather than assuming either way.
Associate level
A mid-entry tier of certification, usually aimed at people who have some hands-on experience with a product or technology. Each vendor defines the tier in its own way.
B
Beta exam
An early version of an exam offered before it is final. Beta exams are often longer and results can take longer to arrive, because the vendor uses the responses to tune the questions and the passing standard.
C
Candidate agreement
The rules you accept before an exam starts, including the ban on sharing exam content. Breaking it can lead to a cancelled result or a ban.
Case study
A question format with a shared scenario (a company, its systems, its requirements) followed by several questions about it. You read the background once and answer multiple items against it.
Certification
A credential showing that you passed an exam, or a set of exams, defined by a vendor or standards body. It confirms that you met a published standard at a point in time.
Compensatory scoring
A scoring model where strength in one area can make up for weakness in another, because only the total counts. Not every exam works this way, so check the vendor’s scoring notes.
Continuing education
Training, courses, or activities that some programs require so you can keep a credential valid. Programs list which activities count and how many units you need.
Cut score
The minimum score needed to pass, set by the vendor through a formal standard-setting process. It is the same thing as the passing score, seen from the test designer’s side.
D
Delivery method
How you sit the exam: at a physical test center, or online from your own space with a remote proctor. Many exams offer both; some offer only one.
Distractor
A wrong answer option written to look plausible. Good distractors reflect common misunderstandings, which is why they can feel convincing.
Domain
A major topic area of an exam, such as security operations or networking fundamentals. Vendors publish a list of domains and show how much of the exam each one covers.
Drag-and-drop question
A question where you move items into slots, categories, or an order, or match items to descriptions. See exam question types for how to approach them.
E
Exam code
The short identifier a vendor gives an exam, such as a letter-and-number combination. Use it, not the certification name, when you search, book, or look up a retirement date.
Exam objectives
The vendor’s published list of skills and topics an exam can test. They are the best starting point for study; see how to study for an IT certification exam.
Exam blueprint
Another name for the plan that shows what an exam covers and in what proportion. Some vendors call it a skills outline or exam guide.
Exam retirement
The date after which an exam version can no longer be taken, usually because a newer version replaces it. Vendors announce these dates on the exam page.
Exam version
A specific edition of an exam, often tied to a version number in the exam code. A new version can change topics and weightings, so make sure your study material matches the one you book.
Expert level
The highest tier in many vendors’ schemes, aimed at people with deep, broad experience. Naming varies: some vendors call it professional or expert.
F
Fixed-form exam
An exam where the set of questions is chosen in advance rather than adjusted to your answers. Different candidates may still see different question selections.
Flag for review
An exam feature that lets you mark a question and come back to it later. Not every exam lets you go back, so learn the rules first.
Fundamentals level
An entry-level tier that tests core concepts and does not assume much hands-on experience. It is a common first step into a vendor’s certification path.
H
Hands-on lab
Practice where you carry out real tasks in a real or sandboxed environment. You can use labs to study, and some exams contain lab tasks as questions.
Hot area question
A question where you click a region of an image or a choice within a displayed structure to answer. You pick the right spot rather than a lettered option.
I
ID check
Identity verification at check-in, using government-issued identification that matches your registration name. A mismatched name can mean you are turned away, so check the rules in advance.
Item
The testing term for a single question, including its stem, options, and key. You will see it in vendor documents.
K
Key
The correct answer to a question, as defined by the exam writers.
L
Learning path
A suggested sequence of lessons or modules from a vendor or training provider, matched to an exam or role.
M
Mark for review
See flag for review.
Multiple-choice question
A question with a stem and several options, where you choose one answer. Most exams contain many of these.
Multi-select question
A question where more than one option is correct. Some exams say how many to choose, others do not, and how partial answers are scored differs between vendors.
N
Non-disclosure agreement (NDA)
A promise not to share exam content. Most vendors include one in the candidate agreement.
O
Online proctoring
Remote supervision of an exam you take at home or in an office, usually through a webcam, a microphone, and a secure browser. You normally need a clear desk, a quiet room, and a system check beforehand.
Open-book exam
An exam that lets you consult approved resources. Most IT exams are closed-book, though a few vendors allow limited documentation lookups.
P
Passing score
The result you need to pass. Vendors express it differently: some as a scaled number, some as a percentage, some not at all.
Pearson VUE
A company that delivers exams for many IT vendors, at test centers and online. Prometric is another provider doing similar work.
Performance-based question (PBQ)
A task-style question where you do something, such as configure a setting or fix a broken setup in a simulation, rather than pick an option. See exam question types.
Pretest question
See unscored question.
Proctor
The person or system supervising the exam. A proctor checks identity and watches for rule violations.
Professional level
A senior tier in some vendors’ paths, often requiring significant experience. See also expert level.
Prerequisite
A requirement you must meet before you can take an exam or earn a credential, such as holding another certification. Many exams have no formal prerequisites, only recommended experience.
Psychometrics
The science of designing and scoring tests. It underpins cut scores, scaled scores, and the checks on question quality.
R
Raw score
The number of points you earned before it is converted to a scaled score. Vendors rarely publish it.
Readiness
How likely you are to pass if you sat the exam today. Practice results, hands-on confidence, and objective coverage all feed into it.
Recertification
Earning a credential again after it expires, by passing an exam or meeting renewal requirements.
Registration
Booking your exam with the testing provider, choosing a date, time, and delivery method.
Renewal
Extending a credential’s validity before it expires. Methods include passing a shorter assessment, completing continuing education, or both, depending on the program.
Retake policy
The vendor’s rules on retrying an exam after failing: waiting times, maximum attempts per year, and whether you pay again. Read it before your first attempt.
Role-based certification
A credential built around a job role, such as administrator or security analyst, instead of a single product. Its exam tests tasks that role performs.
S
Scaled score
A score converted onto a fixed range so results from different versions of an exam are comparable. A scaled score is not a percentage of questions you got right.
Scenario-based question
A question that places a short story or situation before the options and asks which action fits best. These questions test judgment, not recall.
Seat time
The total time you should plan to spend at the exam, including instructions and agreements. It is longer than the exam clock itself.
Secure browser
A locked-down application used for online exams that blocks other programs while the exam runs.
Simulation
A question that imitates a tool or system with limited functions so you can perform a task. It is less open than a full lab.
Single-answer question
Another name for a multiple-choice question where exactly one answer is correct.
Specialty certification
A credential covering a narrow area in depth, such as one security domain or technology, often beyond the associate level.
Study plan
A schedule that assigns topics, practice, and review to dates leading up to your exam.
T
Test center
A physical location where you sit the exam under supervision, using the center’s computer.
Testing provider
The company that delivers and proctors your exam on the vendor’s behalf. Pearson VUE and Prometric are examples.
Time limit
The maximum time you have to answer all questions. Some exams show a running clock; others show remaining questions as well.
U
Unscheduled break
A pause you take during the exam when the vendor allows it. The clock may keep running, and some vendors do not let you return to earlier questions afterward, so check the rules.
Unscored question
A question that does not count toward your result because the vendor is evaluating it for future use. You cannot tell which ones they are, so treat every question as scored.
V
Validity period
How long a credential stays valid before you need to renew it. Some credentials never expire; many do.
Vendor
The company that owns the technology and the certification, such as a cloud provider or networking company.
Voucher
A code that pays for an exam attempt, bought in advance or provided through an employer, a training program, or a promotion. It often has its own expiry date.
W
Weighting
The share of exam questions that comes from each domain, typically given as a percentage range. Use it to decide where to spend study time.
