Rosanna DeMammos works as a content specialist in the language acquisition division of District of Columbia Public Schools supporting all programming for secondary English-language learners. The growth in the district’s ELL population has led the language acquisition division to collaborate with school leaders in support of older students who are recently arrived immigrants at the beginning level of English-language development. The division aims to help these students transition to life in a new country, graduate from high school and be college-and-career ready. The division has been charged with creating programming to meet the needs of students, nurturing critical community partnerships to support school leaders, as well as educators, and collaborating with internal and external groups in order to ensure that students are prepared for the challenging road ahead. This has led to three initiatives for DCPS – the creation of the ELL summer academic program, the opening of the International Academy at Cardozo Education Campus and future expansion to Roosevelt Senior High School, and an expansion of secondary dual-language programming.
