These students need passports to go to school
Iskandar Educity has 100 students from S'pore who cross Second Link each day
More than 100 children from Singapore travel to Johor daily to go to school in Malaysia's new education hub, Iskandar Educity.
They include Singaporeans as well as children of expatriates based in Singapore. Some families have also moved to Johor so the children can be closer to school, and the parents commute to Singapore for work.
The education centre in the Nusajaya township, just across the Second Link in Tuas, has a cluster of schools of various levels, from pre-school to university.
Three have Singapore operators - the Management Development Institute of Singapore, Raffles University Iskandar and Raffles American School. Others include Newcastle University Medicine Malaysia, the Netherlands Maritime Institute of Technology and the University of Southampton.
According to the Education Ministry, Singapore citizens living in Singapore have to attend national primary schools.
This does not include those who live outside Singapore, for example, in Johor.
A ministry spokesman said that the Compulsory Education Act requires all resident Singapore citizens between the ages of six and 15 to complete primary education in national schools, unless exempted by the ministry.
Said the spokesman: "The policy is intended to provide a strong foundation in learning for all Singapore children.
"Being in Singapore schools also allows Singapore children a common educational experience that builds national identity and cohesion."
