Design And Implementation Of An Online Computer Based Test (cbt) System
[A CASE STUDY OF SPRINGLIGHT ICT ACADEMY, UYO]

1.1 Background of the study

It is widely believed that all tests will one day be delivered on a computer of some sort (Bennett, 1998, 2002). However, it is difficult to accurately predict when this day will come. It has seemingly been just around the corner since the early 1990s, when a handful of early adopters, including the ASVAB (Sands, Waters, & McBride, 1997) and the GRE® (Mills, 1999), signed on to computerbased testing (CBT). Today, dozens of admissions, placement, certification, and licensure testing programs are administered on computer, with the number growing each year. On the K–12 front, several states already conduct their annual accountability testing on computer, and many others are poised to join in. Hundreds of schools or districts also employ CBTs in a formative or diagnostic role in service of instruction.

Computer-based testing (CBT) is an efficient way for test sponsors to provide a secure, consistent environment forcertification and licensure while significantly enhancing the candidate experience. It is common for testing volumes to increase after a full conversion from paper-based testing (PBT) to CBT, often as a result of the availability of a greater number of testing locations and more flexible scheduling and testing opportunities. Migration from PBT to CBT does affect candidate behavior, however, and it is possible for some testing programs to experience brief reductions in demand triggered by candidate apprehension regarding CBT. This sometimes results in either a last-minute increase in testing during final PBT administrations or candidate procrastination to the last available computerized testing date. Therefore, the question facing licensing organizations is how to keep test volumes up and candidate uncertainty down when migrating from a paper-based to a computer-based test?

The key to mitigating test volume risk and ultimately driving an increase in demand is ongoing marketing, candidate education and outreach. In terms of promoting the new computerized testing program, marketing and effective communication can have an important impact on stakeholder acceptance of CBT and comfort with its use.

In order to allay candidate fears and minimize questions, it is prudent to launch a communications campaign early in the conversion process that directly addresses constituent concerns and promotes sustainable program interest. 

1.2 Statement of the problem

The challenges faced with paper based test is overwhelming, they include but not limited to exam malpractice, inaccuracy in marking, delay in marking results.

1.3 Objectives of the study

The nain objective of the research project is to design and implement an online computer based test system. Specific objectives of the research paper are:

1. To develop a CBT system that automatically generates exam numbers for students.

2. To develop a CBT system with enhanced security features to avoid exam malpractice.

3. To design a CBT system with real time processing of results for candidates.
