The TV series should be out soon, but a group called Genjo released an OVA:

Not sure about the content of the OVA, but it may have some spoilerish material for the TV series, but who knows... I don't think it matters much anyways.

Based on the seinen manga by Watashiya Kaworu, serialised in Comic High!. NOT related to the other Kodomo no Jikan by Goto Akira!

It`s the cute ones you`ve gotta watch out for...

23-year old school teacher Aoki Daisuke has a huge problem. One of his precocious 3rd Grade students, Kokonoe Rin, has the hots for him?! Yes, mischievous Rin has proclaimed herself to be Daisuke-sensei`s girlfriend and is now on a warpath to win him over or cause him to lose his job...whichever comes first!
Besides Rin, Daisuke`s got other problems to take care of -- one of the students in his class, Mimi (one of Rin`s friends), hasn`t been attending school recently.
Here's a description from the manga:

Taken from Matthew's Anime Blog:
Daisuke is a 23 year-old new schoolteacher. He ends up being put in charge of a 3rd grade elementary school class since the previous teacher quit, and in that class there's a girl who's quite a troublemaker--Rin Kokonoe. You could call her a masegaki (used to describe a kid that acts more like an adult in some ways), and she's also part tsundere (though more dere than tsun).

Seven Seas has canceled Kodomo no Jikan's (Nymphet) licensing due to some so-called "disturbing" content. Read about it on Matt's blog.
