List of virtual schools
There is a useful but very incomplete list of virtual schools at http://en.wikipedia.org/wiki/Virtual_schools
Our list is building up at Category:Virtual schools.
We also categorise virtual schools by major continental region
Because of the large number of virtual schools in North America, they are categorised by US and Canada.
Soon it is expected that we will have:
Some of these country categories seem too detailed, eg Turkey and South Africa. Others may be needed soon, eg for UK, Sweden and Finland.
Note that Ceased virtual schools (those that no longer exist) have their own category - Category:Ceased virtual schools
Taxonomy of virtual schools
See the project bid (PDF) for some thoughts. This is likely to be a challenging problem and the material at Virtual campus not very useful.
