The Pervasive Needs class at Leary's Brook Junior High taught the rest of the school a lesson in terror on Friday.
They spent the week turning their classroom into a haunted house, then took on spooky roles such as "zombie doctor" and "unlucky patient."
Dozens of students were lined up as a group of girls ran out of the classroom, shrieking.
Teacher Michelle Purchase says it gave students from other classes a good fright, and an important lesson.
"What we wanted to do is to showcase the abilities of these children and put together a nice production that showcases their talent," said Purchase.
She says students in her class learned a lot from the experience as well.
"They're taking on a lot of leadership roles," said Purchase, who also took part in the fun, dressed as a zombie bride.
"They've had to co-operate in order to do the scenes. Of course, their creativity is coming out."
Judging by the screams coming from the classroom, the event was a spook-tacular success.
