* Bachelor of Arts (BA) in English Language Studies: This is a common undergraduate degree.
* Master of Arts (MA) in English Language Studies/TESOL/Applied Linguistics: Graduate degrees often focus on teaching English to speakers of other languages (TESOL) or the scientific study of language (Applied Linguistics).
* Doctor of Philosophy (PhD) in English Language Studies/Applied Linguistics: A doctoral degree for advanced research and scholarship in the field.
So, there's no single "degree ELS." The term describes the area of study, and the specific degree earned would be a BA, MA, PhD, or other designation *within* that area.
