Every student at every school has a cumulative folder which contains several documents from report grades to shot records. They are usually located in the main office or in the guidance department depending on how the school set it up. All you would need to do is have your parent make a request to see this folder.
If you are referring to transcripts, they are usually requested through the guidance department. I also found this site to be of some help with the request form.
