China's central education authorities have cancelled a deadline for determining children's ages when applying for primary school entrance. The move has now given provincial authorities the flexibility to decide the date to determine children's ages for primary school entrance.

September 1 was set as the first day of a school year in 1992. The Law on Compulsory Education stipulated that all children who are six years old before August 31 should go to primary school on September 1 of the year.

Many insiders believe the cancellation of the August 31 deadline will not matter a lot since the age to receive compulsory education has remained the same.

Xiong Bingqi, deputy dean at the 21st Century Education Research Institute, suggested the introduction of a flexible age for primary school entrance, as children in other countries can start school between the ages of five and seven based on their intelligence and family situations.
