“…The lack of true population-based datasets in the United States makes it difficult to know for certain, but large, multi-site/multi-state studies such as CDaCI, OCHL, and NECAP typically report language outcomes in DHH children that are 1-2 standard deviations below their hearing peers, or language quotients below the 80% threshold (Koehlinger et al, 2013;Tobey et al, 2013;Ambrose et al, 2014Ambrose et al, , 2015Tomblin et al, 2015;Eisenberg et al, 2016;Geers et al, 2017;Lewis et al, 2017;Hoffman et al, 2018;Yoshinaga-Itano et al, 2018). A separate and more recent study of over 336 DHH children between kindergarten and second grade reported similar outcomes on measures of spoken language, with mean scores again ranging from 1 to more than 2 standard deviations below the normative mean (Lederberg et al, 2019;Antia et al, 2020). These values are commensurate with the findings of a large, longitudinal, population-based study in Australia (LOCHI; see Ching et al, 2010Ching et al, , 2018 for language outcomes at age 3 and 5, respectively).…”
