The CELTA IH blog has a lot of really useful links to ELT web sites in the side bar on the right.
The CELTA IH wiki is the document repository, where you will find the assignments, TP templates, course regulations, the annotated timetable etc.
These can be downloaded, usually in two versions (Word and pdf). Some are also available in Pages. Links: CELTA IH blog- click here to go to the blog CELTA IH wiki - click here to go to the wiki
