Over the years I've collected the curriculums of several of the most important shedras in India. A good introduction to what kind of texts are being studied at present day shedras is written by our friends from Berotsana: Tibetan Buddhist Scholastic Education . Also you might want to read about Khenpo Zhenga at the rigpa wiki, who is one of the most important figures in the creation of Shedras some time ago. He is the author of commentaries to the thirteen great texts, which form the basis for most present day shedras, like Namdroling and Dzongsar Shedra.
Another incredible resource is Andreas Kretschmars pdf's, which can be downloaded from http://www.kunpal.com/ . In the first chapter you will find included an Introduction by Dzogchen Khenpo Chöga and Tsoknyi Rinpoche, The History of Dzongsar Shedra in East Tibet, Life Story of Khenpo Kunga Wangchuk, and Interviews with Khenpo Ape, Kyabje Khenpo Trashi Palden, Khenpo Pema Sherab and Khenpo Namdrol Rinpoche's.
Curriculums:
Namdroling Shedra Curriculum
Dzongsar Shedra syllabus (Tibetan only! Scanned syllabus, the actual curriculum starts on page 5)
Mindroling course of study & actual curriculum (taken from website some years ago, but I cannot find it on their current website)
