"We currently have a very small number of students who have been evaluated and these individuals currently remain in their homes waiting to receive the results of their exams.
"All parents have been informed and we have maintained regular communication with our school community to ensure that councils are shared and important information circulated.
"Of course, we will preserve the confidentiality of staff and students, and we will not comment on specific cases."
