Many organizations (both government and nonprofit) publish advocacy reports and collect or disseminate data in the realm of language education.
In addition to being a way to unite professionals in a profession, professional associations often publish research reports or advocacy papers on topics that fall within their purview. This page includes a few examples of professional associations working in foreign language education. Look for a menu link to research or publications if information on these topics is not apparent. If they publish a magazine or journal, it is likely behind a "Members Only" wall so search the publication title in the library catalog.
