Caster Level - Spell Like Abilities

[Kirowan]

A character's caster level when using spell-like abilities is equal to his class level, right? Likewise, a creature's caster level when using his spell-like abilities is equal to his hit die, correct?

I can't find this explicitly stated anywhere in the 3.5 books. I only saw a reference to it in the DMG in the Planes section under wild magic.

Thanks,

Nick

Luckily it's in the SRD (It's in the books as well, you just have to look harder)

For creatures with spell-like abilities, a designated caster level defines how difficult it is to dispel their spell-like effects and to define any level-dependent variables (such as range and duration) the abilities might have. The creature’s caster level never affects which spell-like abilities the creature has; sometimes the given caster level is lower than the level a spellcasting character would need to cast the spell of the same name. If no caster level is specified, the caster level is equal to the creature’s Hit Dice. The saving throw (if any) against a spell-like ability is 10 + the level of the spell the ability resembles or duplicates + the creature’s Cha modifier.
Some spell-like abilities duplicate spells that work differently when cast by characters of different classes. A monster’s spell-like abilities are presumed to be the sorcerer/wizard versions. If the spell in question is not a sorcerer/wizard spell, then default to cleric, druid, bard, paladin, and ranger, in that order.
