Did Alando Tucker's Professor Break The Law?

I was just perusing last week's Sports Illustrated Issue and happened to read the article about University of Wisconsin basketball player Alando Tucker. It is a good story and I recommend it if you have the time. However, that is not why I am wasting your time. It was this revelation by one of Alando's professors regarding a paper Tucker wrote:

I was impressed with the amount of thought he had given to this for someone his age, and I don't mind telling you I gave him an A for the paper.

Most of you may not care but it immediately struck me that there are federal privacy laws regarding a person's academic records and this may have violated those laws. According to this site, schools generally cannot release any information from a student's record without written permission. I don't know if this applies to a professor or just the institution. I assume it is both. Any education lawyers out there care to enlighten us?

Ultimately, it probably doesn't matter because Alando probably doesn't care and getting an A isn't something to be ashamed of.
