preschool?

Does anyone know (roughly) what percentage of placements are in preschool/maternelle? I’m a preschool teacher in the US and am wondering (not urgently) if I might get placed in one for TAPIF. My application emphasized my preschool experience, but I indicated I’d be interested in any education level (which is true). I also expressed a preference for a ZEP school. Thanks in advance for any insight.
