"There are 9,700,000 illiterate individuals in Iran, of whom 143,000 are between 6 and 18 years old," he added.
The official said although Iran's educational system is efficient, there are still schools across the country that lack educational facilities.
"Lack of educational facilities is one reason behind school dropout," Mehdizadeh said.
He noted that about 3.5 million people, who are over 50 years, are unable to establish strong bonds with their kids because of illiteracy.
The official said modern technologies and the use of social networks have widened the gap between the older and younger generations but they can help promote literacy.
Mehdizadeh said about 67,000 students left primary schools in the year to (March 20. 2015), noting that the largest dropout pertains to the southeastern province of Sistan-Baluchestan.
He said unlettered parents or parents with low literacy skills must be blamed for the school dropout in the province.
The official said plans have been devised to eradicate illiteracy among people aged between 10 and 49 years in the near future. Mehdizadeh also said collaboration between state bodies as well as public assistance can help fulfill the plans.
