Secretary for Education, Dr. Uke Kombra provided the numbers, after reports came out in the media of the delay in issuance of teaching diplomas.
As of last week, the Department of Education has been deregistering elementary teachers, and to date has removed 620 of them.
Dr Kombra says these 620 teachers are currently teaching in elementary schools around the country.
After going through teacher qualifications, they found that 620 did not qualify for college, but were enrolled.
