Hi Samus,
 
Here is a Child Development Guide: Five to Six Years, that includes some information about speech milestones...

And here is an interactive Speech and Language Development Milestones checklist that may provide some insights for you as well:

That checklist is also hyperlinked in this article on Education.com:
 
Speech and Language Developmental Milestones

I'm including below some additional resources you may also find helpful.

hello.
by the age of 5.. children normally develop a lot of their speech sounds... except their 'r', 's' and other such sounds difficult to pronounce. Also, blends with these may not be as clear.
