Update a graduate school about observations?

[Fizzysodabomb]

Hi,

I applied for acceptance for M.S. in Speech-Language Pathology/Communication Disorders. I realize that most universities want the observation hours done prior to beginning course work so I've been working on mine. They're now completed, however, I'm still waiting to hear back from a couple schools and I have confirmed that some of them are still reviewing applications. Would it be inappropriate to notify the school during this time of this completion? I always get a little hesitant to contact a school in the review stages.   

Thanks.
