This was made known by the board in its Vol.1, No 27 weekly Bulletin of the Office of the Registrar, which was made available to journalists yesterday.
The board explained that the exercise is aimed at fishing out impersonators and their sponsors so they can be prosecuted.
The board also vowed that it would publish names of imposters to serve as a lesson to others.
According to the board, the step was taken as a result of a huge number of applications it received with the aim of perfecting fraudulent acts that have aided impersonation in the past.
It said that in the course of its attempt to block all forms of malpractices, the board discovered that candidates employed professional examination cheat to register for the examination.
“They register with the candidate’s name and afterwards, apply for the correction of all other details.
“To address this, the board has resolved to revalidate all biometrics of candidates that have taken the boards examination, to fish out these impersonators and prosecute them along their sponsors,” it said.
