1. Unable to continue studying in the original school: students who change classes usually need to provide proof that they cannot continue studying in the original school, such as family relocation and family financial difficulties.
2. Test scores and interview performance: Students who change classes may need to take the entrance examination of Korean No.4 Primary School to assess their academic level and adaptability. At the same time, the school may also conduct an interview to understand the learning attitude and adaptability of the transfer students.
3. School enrollment policy: Different schools may have different enrollment policies and preferential admission conditions. Some schools may prefer to admit local students or students with special backgrounds, so the admission conditions of transfer students may be affected by these policies.
Please note that the specific placement conditions may vary by region and school. I suggest you consult the Admissions Office of Korean No.4 Primary School directly to get the most accurate information.
