I have to translate the title of my college work and I can't decide whether it is correct to say "Colleagues rating system" or "Colleagues' rating system", because I have often seen examples where genitive/possessive is used without apostrophe or character 's' appended to the noun. Unfortunately I have failed to find any resources for this so as a non-native speaker I must ask for your help!
How it really is? Is it possible to omit apostrophe or s in genitive?

Since "colleagues" is a plural noun and has already been added an "s" to pluralize it you do not add a second "s" to produce the possessive form, only the apostrophe. Something different happens when the plural noun does not finish in "s".(like children --- possessive children's...)
