The recommendation letter does not need the seal of the educational administration department, but needs the signature of the professor himself. Applying for a school basically requires a letter of recommendation. It's hard to say whether it's important or not. There must be a forgery, but it's best not to forge the signature. You can print the recommendation letter yourself and then contact the professor. If it is written by the professor himself, it is best, otherwise, you can sign your prepared recommendation letter to the professor. Usually, the professor will read the recommendation letter and sign it when he/she approves it.

The recommendation letter should also pay attention to the following aspects:

1. For the convenience of the school, the full name of the recommended person must be mentioned.

2. Need to explain the understanding period with the recommended person (when to start to know or how long to know), the understanding degree (occasional meeting or close contact) and the relationship (teacher-student relationship, superior-subordinate relationship, colleague relationship, etc.). ).

3. Introduce and evaluate the merits of the recommended person, which is the core of the recommendation letter. It mainly includes the talent, academic performance, research ability, work experience, learning spirit, organizational ability, conduct and personality of the recommended person.

4. It is necessary to indicate the attitude of the recommender, whether it is strongly recommended or reserved.
