Don't know how I missed this because it is pretty big - but Global Scholar was acquired by Scantron at the end of the year. Global Scholar was owned by Knowledge Universe which also has a slice of K12 and was started by the Lowell and Mike Milken (yes that Mike Milken). They are becoming quite the incubator for education start ups.
This is a pretty cool match - you have an LMS, data mining, standards and tutoring company in Global Scholar now combined with a testing organization. Very complimentary products.
The Milkens are bringing business savvy to education. It is fascinating to watch and I will continue to keep an eye on Knowledge Universe which is using technology and business expertise to rapidly become a world wide education powerhouse.
