The students of Kola High School in Kaliganj upazila under the district are attending classes under the trees on the adjacent ground as cracks have developed in the ceiling and pillars of the schoolhouse during the recent earthquakes.

The six-room building of the school was constructed during its establishment in 1961 with the initiative of the locals and 1200 students are currently enrolled there, sources said during this correspondent's visit to the school.

On March 14 last year, Kaliganj upazila engineer declared the building unusable due to its dilapidated condition but the school authorities continued conducting classes there due to lack of any alternative arrangement.

The recent earthquake caused cracks in the ceiling and pillar, making it all the more risky.

"I have arranged classes under the trees as the school building, with cracks on the ceiling and walls, remains highly vulnerable, especially if earthquake occurs again," said Bijoy Biswas, headmaster of the school.

"I am now worried about smooth continuation of classes during the rainy season," he said. 

Manowar Hossain Mollah, upazila nirbahi officer of Kaliganj, said he has sent recommendations to the authorities concerned for construction of a new building for the school.
