Lauren Ackerman is the former History teacher at Ridgeway Middle School seen in the iCarly episode iHave a Lovesick Teacher. She suffers from bipolar disorder.
Ms. Ackerman loves having steady boyfriends, but frequently tends to be obsessive over them. This is what happened while she dated Spencer. She asked him why he didn't return six of her calls, which she kept track of in a notepad. After the scene Ms. Ackerman made, Spencer felt weirded out about it, so she tried to make Spencer like her by giving him a PearPod (with illegally downloaded music) and a panda-pig, a stuffed animal that had the combination of Spencer's two favorite animals: a panda and a pig.
Ms. Ackerman tends to take her emotions out on her students, usually after a break-up with a boyfriend. After one of her nasty break-ups, she yelled at her students and forced them to do 10 to 15-page essays on subjects she never discussed in class. But once she began dating Spencer, Ms. Ackerman suddenly became a fun teacher. Her attitude towards her students has even changed as well. She offered the class caramel apples, and even invited them to go ice skating with her. However, when he broke up with her (for being psychotic), she began behaving worse ever; she gave the students a pop quiz that would count a 90% of their final grades, for which she gave an F to everyone.
At the end of the episode, she appeared on iCarly. Carly and Sam had the viewers vote on whether she and Spencer should make up or brake up, and the audience agreed that they should indeed break up. But during the interview, Ms. Ackerman had revealed that, for the PearPod she gave Spencer as a gift, she (illegally) downloaded 500 songs from a music sharing website. Carly made sure that the FBI were watching, and the next day, at school, she was arrested.
Lauren Ackerman was played by Jessica Makinson.
