Can a DM check to see if stealth is working properly with PCs? I have noticed that a character with a hide and move of 15+ is being spotted easily by most PCs. They may have good spot gear on or something, but I am curious if the mechanics are working properly.

15+ is not very high, at all. Taking into account lighting bonuses and movement penalties, it's not surprising.
If you are moving and your target is standing still, they get a +5 to hear you, btw. Likewise if you are standing still and they are moving, they get a -5.
There are a bunch of different penalties/bonuses, but until you get around 25+ you are going to be heard easily and quickly, even by PCs with less than 5 or no spot/lsiten ranks at all, without fail. Sorry!
easiest way to look at it is this.
you make spot/listen checks constantly at a roll of 1d20
if you have 15 h/ms that means that people who have no spot/listen -at all- will spot or hear you 25% of the time.
I think people make spot/listen checks every now and then on a time interval.
It's working properly.
For Spot:
* +10 DC if the spotter is in combat.
* +5 DC if the target is standing still.
* -5 DC if the spotter is standing still.
* Size modifiers (tiny: +8, small: +4, medium: 0, large: -4, huge: -8).
* Area spot check modifiers.
* +5 DC for stealthed players (only), if they are in the back arc.
* +5 DC at night if the spotter does not have a light (or darkvision).
* -10 DC at night if the target has a light on them.
For Listen:
* +10 DC if the listener is in combat.
* +5 DC if the target is standing still.
* -5 DC if the listener is standing still.
* +1 DC for every 3 meters between listener and target.
* Size modifiers (tiny: +8, small: +4, medium: 0, large: -4, huge: -8).
* +5 DC for every 40cm of object (including creatures) between listener and target in outdoor areas.
* +2 DC in indoor areas if the line of sight is blocked and the target is within 4 tiles.
* Area listen check modifiers.
