The government school, which started in 1965, will officially complete its first 50 years on September 16.
Minister for Health Nandi Glassie, a product of Enuamanu School, is calling on former students to be part of the celebrations.
He says some of those who were the pioneer students of the school are still around.
“When we were students, we worked very hard and a lot of us at that time were able to get into very substantial jobs,” Glassie says.
“This anniversary celebration is a national pride for the people of Atiu and through the chairman, I invite those who have attended the school in the past to be part of it.
“This is all about the promotion of secondary education on the island of Atiu.”
Enuamanu School chairman Apii Porio says there are plans in place to ensure a memorable celebration.
He says the school has been the best performer in the outer islands for the past couple of years and continues to strive for excellence.
“We have also participated in a number of expos and quizzes in Rarotonga. Academically, the school is picking up well.”
Enuamanu School, which has a roll of 182 students, started out as Atiu Junior High School.
It was renamed Atiu College in 1975 before being named Enuamanu School in 1988.
