I have been teaching teenagers English for almost 40 years, and my selection here is of short stories which work well in the classroom. There are few more unforgiving audiences than schoolchildren, and so you can be sure these stories have survived that test. I have read all of them out loud: no-one is too old to close their eyes and listen, and a live audience really tests the quality of the writing.
That's a good list for the students. Good luck!
