In 2014, the Education Facilities Company Limited (EFCL) offered to build a new school and wanted to move the children out - a move the PTA disagreed with.
One parent, Mr. Patrick Antoine, told C News the planned work isn't complete.
"About a year ago, the project stopped. Within recent weeks, we have reports that the contractor is demobilising. They are moving their equipment and their material from the site so it means that the project is not going any further and we want to know from EFCL and the Ministry of Education what's next. When are we going to get the school? Even if it's Phase One."
Mr. Antoine said the work also prevented the children from enjoying outdoor activities.
"There are no recreation or play facilities for the children right now. It has been like that for over two years so it's in a very cramped environment and the children have to remain in their classrooms for eight hours a day."
Another parent said the conditions at the school were not suitable for learning for the 400 students.
When C News contacted the Ministry of Education, we were told a school supervisor is expected to meet with the parents later this week.
The Ministry said it was not aware of the new problems at the school. Asked about the halt in construction, the Ministry said Education Minister Anthony Garcia is in talks with the Ministry of Finance on allocation of funds to complete construction at schools across the country.
