A TeachMeet (TM) is a form of free Continuing Professional Development (CPD) that originated in 2006 in Scotland, and has since been known under many guises; guerrilla CPD, unconference, and bottom-up CPD. From the very first TM, which took place on the peripheries of an educational conference, there have been certain characteristics that define this teacher-led CPD. The by-line for a TM is 'teachers sharing ideas with teachers'. As this strapline suggests, the presenters at a TM are also the attendees; they are there to learn from each other at a utilitarian meeting. This chapter describes an example of a themed event on Modern Foreign Languages (MFL) and discusses the benefits and potential drawbacks of TMs. [For the complete volume, see ED612143.]
