All these files are provided as PDF files. This is a form of file that shows you the page exactly as it is designed to be seen, whatever your equipment, and is small and quick to download. PDF files are increasingly being used as a way of distributing documents over the Internet; for example Ofsted reports are available on the Internet as PDF files. 

To read a PDF file you need a special piece of software called the Adobe Acrobat Reader. This is free! You may already have it on your network or bundled with your computer. If you are not sure, try downloading one of the files above and clicking on it. If it opens, then you already have the reader and need nothing more. 

If you don’t have the reader you can download it from here:
