The Fijian Teachers Association says at least one teacher is retiring every couple of days, leading to a shortage of qualified staff in the country's schools.
The association's general secretary, Maika Namudu, says the move by the interim regime last year to lower the retirement age for public servants to 55 has a negative effect on the country's education system.
"We lose about 200 teachers, that's for the year, for last year. And that's a big number for 12 months. And it's forbidden to replace them."
Maika Namudu says the retired teachers should be replaced to enable smaller class sizes and a better standard of teaching.
