Article Submission System PER General Guidelines and User Templates updated. Dear Authors Unfortunately, it has been announced by ERIC that the indexing process has been paused for two years as of Volume 10, Issue 2, on the grounds that the number of articles published in our journal has increased since the year we started to index in ERIC. 17 March 2023. Distinguished Authors, Please be informed again herein that PER is indexed by ERIC. ERIC announced last February that it had updated its policy for the indexed journals within its scope. In this context, it was also announced that should an increase of noticeable sort occurs pertaining to the number of articles published by the said journals considering the first day of their admission to ERIC, they would be monitored closely and the indexing process might be paused for two years- if deemed necessary. Please click here to access the disclosure in question published by ERIC. To this end, we would like to declare that the number of articles to be published in each issue as of March 2023 has been limited to 15 in order to avoid any problems to be caused in this direction. Thank you for your understanding and cooperation.
