Mr Chukwuemeka Obua, the Public Relations Officer of the service, said this in an interview with the News Agency of Nigeria (NAN) in Abuja on Wednesday.
Obua said this was to prevent a reoccurrence of the 2014 recruitment where a stampede was recorded at various centres across the country due to large crowd of applicants.
He said the CBT would also be used to conduct the examination in order to test the computer literacy level of applicants.
He said this was a basic requirement for employment into the service.
`` This is the process that will be adopted for the recruitment in order to prevent the reoccurrence of the past incident. Four or five computer centres will be designated in each state of the federation.
`` Applicants will be divided according to these centres and they will be communicated online individually the date they are required to sit for the examination and the location in order to prevent over-crowding in centres and cases of non-applicants in attendance,” he said.
The spokesman said the CBT was a global trend accepted and used worldwide to conduct examinations.
He said the device was chosen to prevent the rigours associated with paper-based examinations.
He said that applicants would not be required to bring any writing materials; rather, they would only need their password which was the registration number to log into the computer, answer the test and submit online.
Obua said after the test, successful applicants would be contacted individually and asked to report to designated immigration offices across the country where they would be further examined.
`` At this stage, we will do the physical examination to check the height, presence of any physical disabilities and general state of health of applicants to ensure that they are fit to carry out their duties when employed.
`` Documents of applicants will also be reviewed during the examination after which successful candidates will be contacted online informing them of their acceptance into the service," he said.
NAN reports that applications for recruitment into the NIS which commenced on Feb. 9 closed on March 22. (NAN)
