Illinois Institute of Technology’s English Language Services (ELS), within the Illinois Tech School of Applied Technology, has been accredited by the Commission on English Language Program Accreditation (CEA) for the period of April 2018 through April 2023. ELS has been granted a five-year initial accreditation, which is the maximum a program can receive when applying as a new site. Only one-third of sites that apply are awarded five years when seeking accreditation for the first time.

Being accredited signifies that programs and student services operated by English Language Services (ELS) meet the CEA Standards for English Language Programs and Institutions. ELS offers the Intensive English Program (IEP), the English Language Program (commonly referred to as PESL), Professional Communication Advancement (PCA) in partnership with Stuart School of Business, English for Design in partnership with Institute of Design, and Language for Law Pre-Matriculation Program in partnership with Chicago-Kent College of Law. The mission of ELS is to provide engaging English language instruction in a dynamic learning environment relevant to the academic and professional needs of non-native learners.
