I’m pretty sure I saw something similar recently, but I’m unable to track it down.
As for school scripts, you could start here: http://www.fontshop.com/fontlist/genres/school_scripts/
But this type of scripts tend to be monolinear.

A very close font is called Cursif and may be found with a Web search.

Florian Hardwig is the go-to-guy on school scripts. He'll probably chime in sooner or later. That said, there is not much "school" going on in your sample. No third grader would ever write like this, unless off course he's the next Ale Paul.

Thanks to Mike’s suggestion, I think I found it on http://www.dafont.com/theme.php?cat=602
