JAMB CBT Test Errors: Causes, Consequences, and Solutions

The Joint Admissions and Matriculation Board (JAMB) Computer-Based Test (CBT) is a pivotal examination for Nigerian students seeking admission into tertiary institutions. While the shift to CBT has modernized the examination process, it has also introduced new challenges, notably test errors that affect candidates’ performance and outcomes.

Understanding these errors, their causes, consequences, and remedies, is essential for candidates, educators, JAMB officials, and policymakers committed to fairness and transparency in Nigeria’s educational system.

Understanding JAMB CBT Test Errors

JAMB CBT test errors are technical or procedural mistakes that occur during the computer-based examination or in the processing and reporting of results. These errors can take various forms, including missing exam questions, incorrect scoring, system glitches, or delays in publishing results.

Such issues undermine the integrity of the exam and place candidates at an unfair disadvantage, causing stress and uncertainty about their admission prospects.

Common Types of JAMB CBT Test Errors

Understanding the common types of errors encountered during the JAMB Computer-Based Test (CBT) is crucial for candidates, educators, and officials to ensure a smooth and fair examination process. These errors can broadly be categorized as follows:

Technical Glitches During the Exam

Technical issues such as system crashes, server failures, or software bugs can abruptly disrupt candidates’ ability to complete their exams. For instance, during the 2025 UTME, faulty server updates in Lagos and Owerri zones caused failures in uploading candidates’ responses, affecting over 379,000 candidates. These glitches may result in lost answers or forced exam restarts, causing significant stress and potential score impacts.

Data Transmission Errors

Problems in the transmission or recording of candidates’ answers can lead to missing or incomplete exam data. This can happen when answers are not properly saved or uploaded to the central JAMB servers, resulting in incomplete or missing results for affected candidates.

Incorrect Score Calculations

Errors during the marking or result processing phase can produce inaccurate scores. Sometimes candidates receive scores that do not reflect their actual performance, either due to software bugs or manual processing mistakes. Such inaccuracies can unfairly disadvantage candidates in the admission process.

Result Display Issues

Candidates occasionally encounter problems like missing subjects on their result slips, incomplete results, or “No Result Yet” statuses on the JAMB portal. These display errors delay admission procedures and cause confusion and anxiety among candidates and their families.

Human Errors

Mistakes during candidate registration or data entry can cause mismatches between candidate information and exam records. This includes incorrect personal details, wrong subject combinations, or errors in biometric data capture. Such human errors can affect exam eligibility or result accuracy, sometimes leading to disqualification or the need for re-examination.

Additional Insights

Many of these errors are compounded by candidates’ unfamiliarity with the CBT system, poor time management during the exam, or failure to follow instructions carefully. For example, some candidates submit their exams prematurely or fail biometric verification due to improper thumbprint capture, which also contributes to exam errors and disqualifications.

Summary of the Common JAMB CBT Test Errors

By recognizing these common errors, candidates can take proactive steps such as practicing with CBT simulators, carefully verifying registration details, and reporting any irregularities promptly. Meanwhile, JAMB must continue to improve its technical infrastructure and support systems to minimize these issues and uphold the integrity of the examination process.

Why JAMB CBT Test Errors Occur

Several interrelated factors contribute to the occurrence of errors in the JAMB Computer-Based Test (CBT), impacting the examination’s smooth administration and the accuracy of results. Understanding these causes is vital for stakeholders aiming to improve the system’s reliability and fairness.

Technical Infrastructure Limitations

Nigeria faces significant challenges with its ICT infrastructure that directly affect the CBT process. Many examination centers, especially in rural areas, suffer from inadequate or outdated computer systems, unreliable internet connectivity, and frequent power outages.

According to studies, much of the infrastructure supporting automated examinations is either obsolete or overstretched in terms of capacity and reliability. The lack of broadband penetration and erratic power supply means candidates sometimes experience interrupted exams or data loss, undermining the integrity of their test performance.

Overloaded Systems

The JAMB online platforms and servers often experience heavy traffic during peak periods, such as on result release days. This overload can cause server crashes, slow response times, or failure to upload candidate responses properly.

For instance, in the 2025 UTME, faulty server updates in Lagos and Owerri zones led to the failure to upload answers for over 379,000 candidates. Such system overloads result in delays and errors in processing and publishing results.

Software Bugs and Glitches

The CBT software itself may contain bugs or design flaws that cause questions not to load correctly, answers not to save, or the system to freeze during exams. These glitches disrupt candidates’ ability to complete their tests uninterrupted and may require restarting the exam or rescheduling, which is stressful and unfair to candidates.

Human Mistakes

Errors during candidate registration, such as incorrect data entry or biometric capture failures, can cause mismatches between candidate information and exam records.

Manual handling of data during verification or result processing also introduces the risk of mistakes affecting score accuracy or eligibility. Additionally, some CBT centers are privately owned and may prioritize profit over quality control, leading to lax supervision and increased errors.

Malpractice Investigations

When JAMB suspects examination malpractice at a center, it may withhold or delay the release of results for all candidates involved, including innocent ones. This precautionary measure, while necessary to uphold exam integrity, can cause frustration and uncertainty for candidates caught up in such investigations.

Supporting Evidence from Research and Reports

• A 2013 study highlighted that Nigeria’s lack of ICT infrastructure and human skills to integrate technology fully into education hampers the effectiveness of CBT exams.
