Kathleen, a friend of mine whom I studied with in Madrid, let me know about a Masters program in Alcalá back in January. It is through a the Instituto Univeritario de Investigación en Estudios Norteamerianos Benjamin Franklin (Instituto Franklin) of the
Universidad de Alcalá!
They have a program called the "Teach & Learn in Spain Program" which gives American students a chance to study get a Master´s from the Universidad de Alcalá while doing a paid internship teaching at a school somewhere in Madrid (or the surrounding areas).
I'm in the process of collecting the necessary paperwork, but the fact that I've been accepted at all means that hopefully in September I'll be in Spain :)
