This is a generous allocation of credits and should last for the duration of a one year subscription for a typical school.The Esri UK ArcGIS Online for Schools resources include some generic (not education specific) getting started videos (Esri UK made) and a getting started PDF (Esri Redlands). There are also videos about the administration of ArcGIS Online (a mix of UK and US) but again, these are generic. And despite the demand in the U.S. (and I'm sure in the U.K.) for best practices information for organizations in general and educational organizations in particular, no such guidance is provided.
I share this information since I think it's valuable to see how different distributors support education. Clearly, in the U.S. the focus seems to be more on district, state and other broad licenses, rather than a single school.
