NDTV publishes daily “School Assembly News Headlines” editions for September 16, 17 and 18. Each edition presents a roundup of topics described as “Top National, International, Sports News,” intended to be used during school assembly time, with an invitation for readers to share their thoughts in the morning.

The sources provided do not include the specific news items included in each day’s headline list, so the content differences between the September 16, 17 and 18 editions cannot be assessed here. What can be confirmed from the available text is that NDTV treats these as recurring, date-stamped bulletin-style posts and maintains the same overall structure and theme across the three consecutive days.

Because only the generic descriptions of the editions are available, there are no additional angles—such as differing emphasis on particular stories—shown in the supplied material. A fuller comparison would require the full headline lists from each date.
