All the 2018, Grade Seven, Nine and 12 examinations have been suspended indefinitely following malpractices.
Some teachers in Lusaka and other parts of country confirmed this morning that the government had decided to suspend the paper which had leaked.
"We have just told the pupils to go back home, because the paper had leaked," revealed a source.
Minister of General Education David Mabumba announced the suspension at a media briefing in Lusaka.
Mr. Mabumba says investigations have been instituted to ascertain the extent of the alleged malpractice.
He said that it is unfortunate that the Mathematics paper two for Grade Nine which was supposed to be written on Tuesday was leaked on social media.
Mr. Mabumba says the Examination Council of Zambia -ECZ- has also nullified the leaked Mathematics paper in accordance with the ECZ Act Chapter 137 of the Laws of Zambia.
The Minister has further warned perpetrators of serious punishment and reparations once found.
