In our district (in BC, Canada), the student's file is the property of the parent and the district is just the custodian, so... legally we have the right to see anything the file contains, including all test scores.
The only time I've been denied access to something in DS's file was when I asked to see notes taken by the TA, and I was refused for privacy reasons because in that particular instance she had made notes about several students in the same log. (I intended to asked if I could have a copy with the other students' names blacked out but I never did).
