Rules for writing in radio include writing simply as if talking to a friend, including the key details of who, what, where, when, why and how in the story, and keeping sentences short and to the point. Stories should be 3-4 sentences with numbers written out and names, ages and locations clearly identified. Ensure details in the script are not repeated in audio clips and statistics are put in context. Avoid abbreviations unless common and read scripts aloud to check they sound natural when spoken.
