The source, who spoke to Anadolu Agency on condition of anonymity due to restrictions on speaking to the media, said a total of 626 institutions, including 524 private schools and 102 other institutions such as dormitories and test preparation centers, will be closed down by the ministry.
Legal proceedings have been taken against institutions that have links to the Fetullah Terrorist Organization (FETO) on charges of "crimes against the constitutional order."
Turkey has also suspended more than 21,738 teachers amid the nationwide FETO investigation.
Turkey's government has said the attempted coup was organized by followers of U.S.-based cleric Fetullah Gulen, who is accused of a long-running campaign to overthrow the state through infiltrating Turkish state institutions, particularly the military, police, and judiciary, forming a “parallel state.”
At least 240 people, including members of the security forces and civilians, were martyred during the failed putsch, and nearly 1,500 others were wounded as they protested it.
