Most periodicals are published without certificates. Certificates are of little significance to the authors of published papers. Their article has been published, which is the best proof No certificate is required at all. Moreover, in the process of applying for a professional title, the author does not need to submit a certificate. The most important thing is to search the page of the article and the page where the article is published. When applying for a professional title, you can submit copies of these two pages. There are few requirements for certificates in this respect. Some authors mistakenly believe that.
If you want to evaluate the professional title, the paper must be published first. If you don't see the publication, you can't prove the success of the paper. Secondly, you may not be able to evaluate the title after reading the publication. Some units are very strict about this, and the papers must be found in the corresponding database before the titles can be evaluated. Therefore, when evaluating the topic of the paper, you must read the published one.
