if you are going to have things on your site YOU NEED to put them on there
for a teacher a parent needs a link on your site to go download a file but as we said Make sure it is a file type you can have loaded to your site and more too
just like on a school website itself you have to have links to the important pages around or files to download and more ON the website and that stuff won't be there UNLESS the person making the website puts things on the site and publishes it
