There are no Department of Defense Dependents Schools (DoDDS) located in Busan. The two fully accredited international schools in Busan are Busan International Foreign School (BIFS) and Busan Foreign School (BFS). It is possible for military dependents to attend other Korean and private schools in Busan as well. However, service members must register and get approval through the Non-DoD Schools Program (NDSP) at https://goo.gl/g4hJpJ
Like DoDDS, there is no DoD childcare available in Busan. Korean daycare/preschool can vary in cost, depending on the school and program.
Both International Schools, as well as other public and private schools in Busan, offer Pre-K, however, DoDEA does not cover the cost and parents should contact the schools directly about Pre-K fees and programs to waive those costs. Please talk with your sponsor and other military spouses for referrals and always ask for references.
Both BFS and BIFS charge fees that are not covered by Department of Defense Education Activity (DoDEA), but both schools offer programs to DoD and other U.S. government employee families to cover these costs. Please contact the schools directly for more information.
