While the term is most commonly applied to language-specific skills, competency in academic language also bleeds into a wide variety of related non-linguistic skills that are difficult or impossible to separate out from language ability, including foundational academic skills (organizing, planning, researching), cognitive skills (critical thinking, problem solving, interpreting, analyzing, memorizing, recalling), learning modes (questioning, discussing, observing, theorizing, experimenting), and work habits (persistence, self-discipline, curiosity, conscientiousness, responsibility), in addition to other forms of literacy required to succeed in modern schools, such as technological literacy, online literacy, media literary, or multicultural literacy, among others (for a related discussion, see 21st century skills).
