From the past to the present, the two types of spoken and written Farsi (Persian) have been common in the society, and especially after the spread of social media and the necessity of online interactions, written Farsi has been used more and more by users in cyberspace. This development requires that timely action be taken to organize informal Persian writing methods so that a valid model can be placed in front of users and guide them in this direction. In 1403, this issue was published in the form of a booklet for the attention of relevant groups in the Persian Language and Literature Academy, which is expected to help in planning and organizing this type of common writing. Through a field research, this article has counted the neographies used in the "Shad" student system in the first period of high school in the academic year 2019-2020 and then categorized them. In the meantime, some parts of the recently approved script (informal Persian) have also been highlighted and new categories have been added to it according to some examples. The results of the present study show that out of the 501 recorded , phonetic neographies, spelling neographies, neographies resulting from morpho-neographies phonemic changes, context-based neographies and finally other neographies have the highest frequency, respectively.
