Adamu gave the warning while monitoring the 2018 Batch A Teacher Professional Qualifying Examination (PQE) in Abuja on Saturday.
No fewer than 22,000 would-be teachers sat for the Computer Based Teachers PQE nationwide scheduled to hold from June 7 to 9.
Adamu, represented by Mr Sonny Echono, the Permanent Secretary, stressed that if teachers were not qualified and properly equipped, the products who are the students would also fall short and ultimately the country will suffer.
“The person at the centre of it all is the teacher, not the pupils and if the teachers are not qualified and properly equipped then how can they give our children the best.
“So as a government we are insisting that we must raise the standards; we must become like other countries of the world.
