The recommendation letter objectively evaluates the learning level, learning ability, potential development direction, interpersonal ability, subjective initiative and adaptability of high school students' applicants from the perspective of a third party. This is somewhat similar to the Han Dynasty, which regarded "respecting filial piety and saving righteousness" as an important channel for young people to reach their official career. Each learning stage reflects a person's potential learning ability. It is the continuation and promotion of the previous stage, and it is also the foundation and foreshadowing of the latter stage. Therefore, it is more convincing to prove the applicant's background conditions from the perspective of referees (usually class teachers or classroom teachers) who directly observe and explore this ability. A letter of recommendation with compact structure and clear logic will set off the background of the applicant.
A survey of a student in an American high school is measured from a comprehensive perspective. In addition to personal statement-the applicant introduces himself, the recommendation letter promotes his own documents from his own point of view, that is, from the standpoint of a third party to know, understand and introduce the applicant's comprehensive quality and outstanding characteristics, which is very important for school admission.
Letter of recommendation is the most important school application document besides self-report, which plays the role of introduction and proof from the side. Because of its objectivity, the recommendation letter can play a role that the self-report can't. Therefore, the content of the recommendation letter should be more objective and specific, and cannot be exaggerated and whitewashed.
