The president of the Federation of Teachers in American Samoa, Peni Te'o, says some of his colleagues are anxious about a new mandatory test.
Five hundred public school teachers are to be tested on their reading comprehension, writing and basic mathematics this Saturday as part of a reform of the education system.
Teachers need to pass the test, known as Praxis I, to be able to continue teaching.
The director of education, Vaitinasa Dr Salu Hunkin Finau, says if teachers don't pass the first time they can sit the test again but they must pass on the second attempt.
Peni Te'o says some teachers are wary of the change.
"Initially most of them because here at Leone High School where I'm at I have 86 percent of the teachers have not taken the test. There is some nervousness making it mandatory to take the test and also the fear of failing."
The director of education, Vaitinasa Dr Salu Hunkin Finau, says the motivation is to help raise student achievement.
