The Solomon Islands National Teachers Association is urging the government to employ experienced teaching staff to stop what it says is a decline in academic standards.
The Solomon Star reports the teaching industry has recruited hundreds of untrained teachers in the past years to cater for the growing number of high schools throughout the country.
The Teachers Association says the downward spiral will continue unless the government intervenes.
An industrial relations officer, John Lee Hatimoana, says there is clear evidence that the academic standard is dropping, with about 30 per cent of the current teachers not being qualified.
He is appealing to the government to let more students undergo teaching studies.
