In Smart School, if you want to change text labels like if you want to change text lebel of "Academics" to "Academics Settings" then for this you should go to the Language file location, here first you should select the Language file according to your country language and do changes in that language file.

For e.g. if you want to change text lebel of "Academics" to "Academics Settings" in English language then go to the file path location \application\language\English\app_files and open system_lang.php file then serach for the keyword "Academics" 



Now replace it with "Academics Settings" then save it.



After save changes it will look like below image at Smart School site.



Note- Please make sure you have done changes in proper format (like Academics Settings must be under single inverted commas) otherwise code will cause an error.
