Officially, yes. Most teachers/professors will accept it either way. ANSWER In American English, it depends on whether or not the "h" is sounded. In "hour," it is not sounded; therefore, we say, "an hour." In "hostage," it is sounded; therefore, we say, "a hostage." [Some U.S.A. dialects use "a" in some words even when the "h" is not sounded. In the South, for example, one hears, "I'll be back in a (h)our."] That view rests on the general rule that if a word begins with a vowel we use "an," if it begins with a consonant, we use "a." Some h-words have alternate pronunciations, with the h and without. For example, the word "homage" is homage or omage -- or, in modern film lingo "ohMAGE." In America, we would say, "a homage"; "an omage"; "an ohMAGE." [spelvin]
It is not necessary to use the full form an before any word beginning with an h, unless the h is silent, as in "hour." However, and especially in Britain, it is often used when the stress accent of the word is not on the first syllable. For example, we will say "a history," but we may say "an historical novel."

It is a topic of on-going and sometimes rabid debate whether it is a or an before a word beginning in h. Which is correct depends on which side of the argument you sit. Personally, I have never met anyone who uses anything but a in speech.
