The International and Heritage Languages Association was founded in 1977 to bring together heritage language schools in Edmonton, Alberta, Canada, which were operating in isolation. When teachers participated in a conference, they discovered that their challenges and rewards were similar across schools, regardless of the languages they taught, and they continue to collaborate and learn from each other.  

Other organizations also focus on heritage language learners and provide information and resources.

The Alliance for the Advancement of Heritage Languages has many helpful resources, including profiles of heritage language programs and Heritage Briefs on many different topics.

The Heritage Language Schools of Eindhoven (HLSE) seek to maintain and develop the heritage languages of children in the Netherlands.

The National Heritage Language Resource Center (NHLRC) at UCLA, one of 16 Language Resource Centers funded by the U.S. Department of Education, develops effective pedagogical approaches to teaching heritage language learners, by creating a research base and by pursuing curriculum design, materials development, and teacher education.
