CAL

CAL is an acronym or abbreviation that can refer to several different terms across fields such as education, linguistics, dentistry, nutrition, and regional names. Because it has multiple distinct meanings, the interpretation depends on context.

In learning technology, CAL most often stands for Computer-Assisted Learning or Computer-Aided Learning, referring to educational activities that use computer hardware or software to deliver instruction, practice, or assessment.

CAL can also denote the Center for Applied Linguistics, a U.S.-based nonprofit organization that conducts research and provides resources on language education, literacy, and language policy.

In dentistry, CAL stands for Clinical Attachment Level, a periodontal measurement used to quantify the level of soft-tissue attachment around a tooth and to assess gum disease progression.

In nutrition, Cal (capital C) is a unit of energy equal to one kilocalorie; nutrition labels may list Calories, with one Calorie equaling 1,000 actual calories.

In common usage, CAL or Cal appears as a nickname for the state of California or the University of California system, reflecting informal naming rather than an official acronym.
