There are three categories of officials: supervisors, invigilators and inspectors. Supervisors are teachers nominated by the various State Ministries of Education. They are actually responsible for conducting the exams at the various centres. It is their responsibility to collect question papers from the custodian and return answer scripts to the custodian centres.

Invigilators are usually teaching staff nominated by their school principals to assist the supervisors at the centres, while inspectors are WAEC staff members who go from one centre to another when the examination is in progress.

No. Instead it issues statements of result to the owners of lost certificates or, when necessary, confirms their results for a fee.

WAEC also issue attestation of result document for damaged and lost certificates.

First, a committee of experts draws up a marking guide. All appointed examiners are then thoroughly drilled in all aspects of the marking scheme in a simulated marking exercise called co-ordination. Actual marking does not start until the coordinating officers are satisfied that all examiners know what is required of them. Even when actual marking begins, the examiners are not left entirely on their own.

They are organised into small groups, each being supervised by a highly experienced examiner called a Team Leader. The Team Leader checks and vets the group members' marking progressively to ensure that they are keeping to the guidelines.

The Team Leaders themselves are supervised by more experienced examiners called Chief Examiners. When marking is finally completed, WAEC still goes ahead to employ another group of people called Checkers. The main role of Checkers is to ensure that all marks awarded by examiners are correctly recorded and transferred to the appropriate score sheets.

The Council usually advertises entry periods and entry procedures in national newspapers. In respect of the WASSCE for example, the Council conducts two exams each year; the first in May/June for school candidates and the second in October/November for private candidates.

Registration for either May/June or the November/December WASSCE is done through the Internet (online). The May/June exam is for school candidates and all entry formalities are undertaken by the schools presenting candidates.

In the case of the private candidates' examination, entry is on an individual basis. A prospective candidate purchases the entry scratch card which enables him/her to complete the entry form on the Council's registration website-www.waeconline.org.ng. A registered candidate subsequently prints out from the website the identification photo card, which contains vital information about the candidate's centre name, location, number and the subjects entered for. The examination timetable and subject syllabuses are also made available to prospective candidates on the website.

It is important to note that once the prescribed fee is paid to the accredited selling agent, a prospective candidate obtains two scratch cards, one for the online registration and the other for the online checking of results.

WAEC does not prepare candidates for its examinations by establishing secondary schools or tutorial centres, and no such institutions are affiliated to the Council.

WAEC provides feedback in the form of Chief Examiners' Report on candidates' perofrmance in the various papers for each examination diet, which helps schools and private candidates to prepare adequately for subsequent examinations. The Chief Examiners' Reports are avialable for sale at the Council's offices nationwide.

WAEC certificates have no expiry date.
