Should the listings be included in the contents page I have a thesis template that does not put the List of Figures, List of Tables etc. in the contents page.

What is the normal practice and what is the normal order for the front matter?

Currently it is:


table of contents
list of figures
list of tables
list of listings
list of symbols
I don't know that there is a "normal" order over different fields (or even within a field). My only suggestion is that if you need to symbols to understand the listing, then maybe symbols should come first.

Otherwise, what you have should be fine. But for a thesis, let your advisor give you the best advice.
