1) Yes you should apply to a school with ESL since the top schools without ESL want your child to have TOEFL of around 90-100.
2) It depends on what your child likes. For a smaller school, he may get more personal attention. For a big school like PA or PEA, they already expect you to be independent and can manage things on his own.
3) Not necessarily. Milton, for example, goes from K-12.
4) None of the better schools are taking a lot of Chinese students now. You should have your son go to a school with diversity, meaning international students.
5) Personally, I advise my students to apply to boarding schools, not day schools, because of friends, activities in the evenings and weekends, etc. I think if you want someone to look for a host family, you should look at the contract carefully. Every company is different.
您好，孩子的英文如果不是非常流利的话（托福也不是非常理想），最好申请有ESL的学校，要不然录取机会非常低。高中的学生数量少并不代表学校不好，反而有些非常优秀的学校是300人以内（例：Foxcroft, Thatchers, etc）。根据孩子的年龄以及能力，可以考虑纯高中或8-12年级。当然，也有学校包括不同的学区（小学部、初中部、高中部. Lower school and upper school etc.），这个不说明学校的质量。国际学生最好不要太多（特别是中国学生）。寄宿家庭可以换掉，但是谈合约时请注意对契约的限制，避免出现额外补偿费用。
