For parents considering Private/International/Bilingual Schools for their children, IBMS is not the best choice because of below reasons :
Fees is too high considering the facilities are very limited and teaching methods are not competitive. Small outside playing area for kids in the school and they mostly rely on public parks in the vicinity for kids outdoor activities. School is only till grade 4 and for those who prefer their child to remain in private school, selecting a school which has classes till 12 will make more sense.
Other Private/international schools in and around frankfurt are better with a moderate increase in monthly tuition fees.
