CBT(Computer Based Testing)exams are becoming increasingly popular, particularly for certification and qualification exams, and are attracting attention as Test Format that improves convenience for Candidate and streamlines exam administration. Compared to traditional paper-based testing, CBT offers a wider range of options for exam dates and Test Center, providing many advantages for both Candidate and exam organizers.

This article explains the mechanism, advantages and disadvantages of CBT (Computer-Based Testing), the testing process, and examples of how CBT is being used.

A CBT (Computer-Based Testing) exam is an exam conducted using a computer.

A CBT (Computer-Based Testing) exam is an exam conducted using a computer at a dedicated test center (Test Center). Candidate use a computer set up for the exam at the test center or designated Test Center, reading the exam questions displayed on the screen and entering their answers using a mouse and keyboard.

CBT (Computer-Based Testing) exams are characterized by the fact that everything from displaying exam questions to recording answers and grading is completed on a computer, significantly improving the efficiency and accuracy of the exam.

Furthermore, unlike traditional PBT (Paper-Based Testing), CBT (Computer-Based Testing) offers a wide range of options for exam dates and Test Center. Candidate can choose their preferred date and Test Center, allowing for flexible scheduling. For example, they can take the exam after work on weekdays or on weekends, fitting it into their lifestyle.

How CBT exams work

So, how are CBT exams conducted? Here, we will explain the mechanism of CBT exams.

Examination environment

The CBT exam is conducted at test centers (Test Center) located throughout Japan. Each Test Center is equipped with a computer and a test booth that are set up specifically for the exam. Each booth is separated by partitions, creating an environment where test-takers can concentrate without being distracted by other Candidate. The design minimizes distractions from surrounding sights and sounds, allowing Candidate to take the exam at their own pace.

Furthermore, test proctors are stationed at Test Center to verify the identities of test-takers and monitor them during the exam, thereby ensuring fairness.

Furthermore, all necessary equipment and software for the exam are provided by Test Center center, so Candidate do not need to make any special preparations. Even those who are unsure about using computers can review basic operations through a pre-exam tutorial.

Furthermore, Prometric is committed to ensuring consistent test quality by standardizing equipment standards, such as unifying display sizes and installing lockable lockers, to provide the same level of environment at all Test Center nationwide. This ensures that test-takers can take the exam under fair conditions regardless of which test Test Center they choose.

What are the benefits of introducing CBT?

Question method

In CBT (Computer-Based Testing), questions are displayed on a computer screen, and Candidate must answer them within a time limit. The remaining time is displayed on the screen, allowing test-takers to manage their time effectively. Another feature not found in PBT (Paper-Based Testing) is the ability to mark answered questions and flag questions to review later.

Answers to multiple-choice questions are recorded by mouse clicks, while answers to written response questions are recorded by keyboard input. For multiple-choice questions, simply clicking the appropriate option records the answer, while for written response questions, it is common to directly type the answer into a text box.

In some exams, questions are presented randomly, or each Candidate is given a different set of questions, meaning that no two Candidate will answer the exact same questions. This helps prevent cheating, reduces the risk of exam content leaks, and contributes to the long-term stability of exam administration.

In the case of multiple-choice questions, for example, automatic scoring is performed immediately after the exam ends, and in many cases, you can check the results right away.

Advantages of CBT (Computer-Based Testing)

CBT (Computer-Based Testing) offers advantages to both Candidate and test administrators. Let's look at the benefits for each.

Advantages for Candidate

One of the advantages of CBT (Computer-Based Testing) exams for Candidate is that, depending on the exam design and format, they offer greater flexibility in scheduling. Often, a wide range of test date options are available, allowing test takers to choose a date that suits their needs, making scheduling easier. Compared to PBT (Paper-Based Testing), the constraint of only having a few test opportunities per year is less pronounced, making it easier to plan your exam schedule while coordinating with work and personal commitments.

Another advantage is the ease of access to the test Test Center. Since the exam can be taken at test centers throughout the country, there's no need to travel long distances, saving time and transportation costs. Furthermore, the quick availability of Test Result is a benefit. A shorter waiting period allows candidates to immediately begin preparing for the next step. Being able to put post-qualification career plans into action sooner is a significant advantage for Candidate.

Benefits for the operators

One of the advantages for the exam organizers is the reduction of physical costs. For example, with PBT (Paper-Based Testing), many costs were incurred, such as the printing costs of question papers and answer sheets, delivery costs to Test Center, and storage and disposal costs for used questions. However, with CBT (Computer-Based Testing), these costs are eliminated, so significant cost savings can be expected in the long term.

Furthermore, CBT (Computer-Based Testing) exams can streamline the scoring process. Automating the scoring process will prevent human errors and dramatically improve the efficiency of the scoring operations. In particular, for multiple-choice questions, the time and personnel required for scoring can be significantly reduced, and challenges such as securing scorers and standardizing scoring criteria can be resolved.

In addition, data management and analysis become easier. Since Candidate data and Test Result are stored as digital data, it becomes possible to improve test quality, such as analyzing Candidate trends and adjusting the difficulty level of questions.

One advantage of digitizing exam questions is the flexibility with which updates can be made. Exam content can be quickly updated to reflect legal changes and technological advancements.

Disadvantages of CBT exams

While CBT (Computer-Based Testing) offers many advantages, it also has some disadvantages. It's crucial to understand these drawbacks and implement measures to minimize them during the testing process.

Disadvantages for Candidate

For some Candidate, a lack of computer skills can be a disadvantage. The need to learn how to operate a computer can be a psychological burden. Those who don't use computers often should especially review the operating procedures before the exam. However, most CBT exams provide tutorials beforehand, so there's no need to worry excessively.

Furthermore, Candidate are concerned about the inability to write on the paper. Those accustomed to PBT (paper-based testing) may find it difficult to perform at their best without being able to think while writing on the question paper. Those who prefer to organize their thoughts by writing on paper when solving calculation problems or complex logic problems will need to find alternative methods.

In addition, the possibility of technical problems such as system failures or power outages cannot be ruled out. In the event of a problem, appropriate measures may be taken according to the regulations of the exam organizer, but this can be a source of anxiety for Candidate. Prometric conducts regular maintenance and works to reduce the risk of failures, ensuring a safe environment for taking the exam.

Disadvantages for the operators

For the administrators, a disadvantage is that implementing CBT (Computer-Based Testing) exams requires specialized knowledge. Since system selection and configuration require expertise, if there are no IT-savvy personnel within the company, support from external experts will likely be necessary.

In addition, ongoing costs are necessary. These include ongoing expenses for operating the test center and maintaining equipment, as well as ongoing costs for system updates and security measures. However, since PBT (paper-based testing) also incurs printing, delivery, and scoring costs, these must be considered in comparison.

Furthermore, the fact that grading of written and essay questions requires human intervention, making complete automation difficult, and that support such as explaining how to use the system to Candidate is necessary, can also be considered disadvantages of CBT (Computer-Based Testing).

Steps to take a CBT exam

Next, we will explain the process for taking the CBT exam.

1. Application for the exam

First, you apply through the official website of the organization administering the exam. In most cases, the application process can be completed online, so you can apply anytime, 24 hours a day. Popular dates and Test Center can fill up quickly, so we recommend applying as soon as possible.

After that, you will pay the examination fee and receive your examination ticket and a confirmation email. After completing your application, you may also receive a confirmation email containing information such as the date, time, Test Center, and required items for the exam, so be sure to check its contents carefully.

2. Entrance Exam

Once your registration is complete, you will take the exam at the designated test center at your scheduled date and time. Many Test Center ask you to check in 15-30 minutes before the exam begins. Please check the specific test page for your exam to confirm the check-in time. Since you may not be allowed to take the exam if you are late, please leave early, taking into account potential delays in public transportation. At Test Center, you will review the tutorial and instructions in your designated test booth before starting the exam.

3. Procedures after the exam

If the results are displayed immediately after the exam ends, you can check your score right away. After checking the results, follow the on-screen instructions to finish the exam. If a score report or certificate of completion is issued, you can pick it up at the reception desk or have it mailed to you later.

For exams where determining pass/fail status takes time, you can check the results on the official website on the designated date. If grading takes time, such as for exams that include written questions, the results will be notified at a later date.

Examples of CBT (Computer-Based Testing) utilization
