Sneak skill
 

I've recently made a rogue who is now level 5 and for whatever reason I cannot raise his Sneak skill. I put a single point in the skill at the rogue trainer though it seems no matter how many times I use Sneak, it never increases beyond 1. Is the skill simply really difficult to raise?

Just to be sure you are using it as often as possible, you can link it to a movement key.

It's beginning to increase now, thank you.
