Ten days after a fire decimated their school, all the students from the East Somerville Community School are scheduled to be back in class learning with their teachers this week.

The 120,000 square foot elementary school was destroyed in a Dec. 9 blaze after an electrical problem in a room heater caused a fiery explosion on the school’s first floor.

After class was cancelled last week, all kindergarten students restarted school in alternate classrooms at the Capuano Early Childhood Center on Monday. Wednesday, Dec. 19, students in grades 1 through 8 were united with their teachers and classmates for their first day back to school since the blaze.

Students in grades 1 through 5 and Unidos grade 6 will be relocated to the Edgerly School and grades 6 through 8 will resume their classes at the Cummings School.

From the beginning of the relocation process, Superintendent Anthony Pierantozzi said keeping classes intact and as close to the East Somerville neighborhood were the two main goals of his plan.

Curtatone said the relocation of the school’s 585 students has been relatively smooth.

“In just a little over a week we found safe and healthy learning environments for all students because the teachers, school officials and the community as a whole stepped up to the plate,” he said.

The East Somerville Community School (ESCS) has been closed to the public since the morning of Sunday, Dec. 9, when a 3-alarm blaze caused serious structural and mechanical damage to the southeast quadrant of the building, and significant fire-related damage to a large portion of the building.

Curtatone said last week he is committed to rebuilding or replacing the school, though it will be a costly task.

“I don’t know how much this will ultimately cost. I know it will be in the millions I just don’t know how many yet,” he said two days after the fire.

This week Curtatone could not say how long ESCS students will be learning in classrooms at the Cummings, Capuano and Edgerly schools.

‚ÄúWe‚Äôre moving forward with establishing a long-term plan but for we are still assessing the damage done in the fire,‚Äù he said.
