The Anti-Corruption Commission has sent letters to 15 schools over allegations of irregularities during admission.
The schools have been asked to explain their policies and provide other information on admission, like seat capacity, before Thursday.
Speaking at a press conference on Wednesday, ACC Chairman Iqbal Mahmood said, the commission received several complaints about corruption and irregularities by schools in Dhaka.
"We followed a sampling process to select 15 schools and asked them for information regarding admission."
The schools are Motijheel Government Boys' High School, Motijheel Ideal School and College, Viqarunnisa Noon School and College, Wills Little Flower School and College, Udayan High School, Government Laboratory High School, Azimpur Government Girls School and College, Agrani Girls' High School and College.
Dhanmondi Government Boys School and College, Mohammadpur Preparatory High School, Saint Joseph Higher Secondary School, Dhaka Residential Model School and College, Holy Cross Girls High School, Monipur High School and RAJUK Uttara Model High School.
Meanwhile, Iqbal Mahmood also said the Commission will get even tougher against graft suspects this year to effectively fight corruption in the country.
"Anti-corruption issues should be inclusive. We want to minimise corruption involving general people...our action will be harsher this year," he said.
Iqbal Mamood said surveillance on corruption-prone public agencies will be strengthened in 2017 and some innovative measures will be taken to upgrade database of the Commission.
Revealing official data, the ACC chief said 13 graft suspects were caught red-handed while taking bribes through setting traps in 2016 and the ACC also filed cases against them. "More traps are coming up this year, too. Those who take bribe and who give bribe are both offenders," he added.
Iqbal Mahmood said the Commission arrested 388 graft suspects in 2016 as they tried to avoid interrogation and court appearance.
He said the ACC filed 339 cases and submitted 528 charge-sheets before courts last year. Graft accused were convicted in 54 percent cases in 2016 while the success rate of the ACC's cases were only 37 percent in 2015.
"But, we want to see cent percent conviction in the graft cases filed by the Commission," he added.
The ACC chairman said there is no alternative to ensuring good governance aiming to achieve sustainable development goals (SDGs) and that is why the ACC is working sincerely to ensure governance through combating and preventing corruption. —Agencies
