Massachusetts SEI Teacher Endorsement Course (RE-600)

The purpose of this course is to prepare Massachusetts teachers with the knowledge and skills necessary to be effective reviewers and instructional leaders of educators who teach English Learners (ELs) to ensure that they are able to access grade level curriculum, achieve academic success, and contribute their multilingual and multicultural resources as participants and future leaders in the 21st century global economy. MATSOL offers this course as part of our mission to promote equity and excellence for English Learners.
