The Reporting Skills and Professional Writing Handbook (2nd Edition) is a self-study programme based on the best of 10 years' experience working with INGOs, NGOs,
GOs and IOs over hundreds of training courses. It's available on CDROM for convenient desktop study, and, for larger organisations, the Trainer Edition is supported by a complete Training Pack. Along with the CD you get the entire programme as a free PDF Ebook.
There's a free download of the first module (Professional Writing and the Writing Process) at http://www.reportingskills.org (requires sign-up, but stick around and there's more to follow) or you can get all the info in one document at http://www.reportingskills.org/synopsis.pdf. (ELD is a registered United Kingdom charity so don't worry about either your privacy or getting a virus.)
The Handbook is already in use by a wide range of development organisations such as CARE, CGIAR, GTZ, UNEP and the World Food Programme. We're sure you'll find it worth your time to take a look.
