Laws involving Massachusetts school work???

I'm not too familar with the laws in the United States. I don't believe that there is such law. In Canada we have the Freedom of Information and Protection of Privacy Act, it basically gives everyone the right to access public government files (courts, census statistics, educational material, etc). However private information (driver licence info, health care, etc) are ensured privacy. For something like a portfolio and not even an academic transcript, it shouldn't be legal binded. See if you can speak to someone from a higher position of authority or have the student consent to the release of the portfolio to you on their behalf.
