有的，可以跟学校申请，单人间会优先给高年级学生

您好：美高学校都有单人间，一般会给11年和12年级的学生，9和10年级的学生基本都住双人间。我们就读家长上周刚刚给我们做了一期分享告知Phillips Exeter Academy在9年级学生也可以选择住别墅，别墅住宿的学生会少一些。

寄宿学校一般会有一些单人间的，但主流是双人间。以下是借花敬佛网上看到的有关该校住宿的信息，供参考：
“There's a huge variety of living spaces at PEA. There are dorms (30-60 students) and houses (8-26 students). Houses do not have 9th graders and are much smaller. Most dorms have three floors with almost all having two students per room (especially right now). There are, of course, singles, but returning students have usually already picked them. Soule Hall (pictured in Eva's answer) is unique (I was in Soule Hall for six years). It has some of the biggest rooms on campus, but there are no floors per se. Instead, the rooms are off of a pair of spiral staircases going vertically up the building. Some rooms have carpet, some have tile and some (like Soule) have hardwood floors. There is no air-conditioning, and students are not allowed to bring one. In general, all the dorms and houses are in good condition, but you should prepare for hot weather in the spring term.”

PEA 宿舍有单人间的，但数量不多，可能要高年级才能争取到。

有单人间，但是给与一些特殊的学生和高年级的学生

有的，不过基本上美高都是到了高年级安排单人间的学生人数会更多一些，这个倒不是主要矛盾了，单人间和双人间各有各的好！
