Update 2014 12 20: The contents of this page have become woefully out of date and it would be more than a full time job to keep it up to date.
My advice is as now as follows:
If you are looking for M&E training opportunities visit the MandE NEWS Training Forum, which lists all upcoming training events. There are many training providers listed there, along with links to their websites
Please also consider taking part in the online survey of training needs.
If you are a training provider, please look at the cumulative results to date of that survey.
I have now deleted all the previous training providers that were shown below
