<p>Every high school student could, in theory, get a peer recommendation from a fellow high school student and submit it to colleges. Every college student could, in theory, write a LOR for someone they know in high school. Every sibling at a college could, in theory, write a peer recommendation letter for their sister or brother who is applying to that college. But — outside of Dartmouth — those types of recommendations are neither wanted nor encouraged. So, IMHO, do not send a peer rec to any colleges that explicitly doesn’t ask for one.</p>
