The Superintendent of Schools for the Archdiocese of New York on Monday gave an update on the Friday night fire at Monsignor Scanlan High School in the Bronx.
Superintendent McNiff says the fire, which started in the school's boiler room, damaged that room, two labs, an office, the chapel altar and sacristy.
The damaged areas have been sealed off and students will not be allowed back into them until they are fixed.
Any students who were supposed to take tests in the school on Tuesday will report to the saint Helena Parish Elementary School.
Parents will receive updates on the school through their IRIS Emergency Alert System.
Those updates will also be posted to the schools website at scanlanhs.edu.
