Quality punctuation?

I notice that the Quality Assurance Agency website commends: a department for "it's" basic information technology skills programme; a university for "it's" teaching review; another for "it's" mission statement; and another for management of "it's" collaborative arrangements.

One university is questioned as to whether "it's" students are equipped to proceed.

"Who is guarding the guards?" inquired the QAA's chief executive Peter Williams a while back. In the case of punctuation, who indeed?
