The state-approved pathway for Core Academic Teachers and Vocational Educators to obtain the required SEI Endorsement

✔ Core Academic Teachers, Vocational Educators
✔ All grade levels
✔ SEI Teacher Endorsement

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.

The SEI Teacher Endorsement Course is a state-approved pathway to obtain the required endorsement for: 

  • Core Academic Teachers (early childhood, elementary, teachers of students with moderate and severe disabilities, English, reading, language arts, mathematics, science, civics and government, economics, history, and geography)
  • Vocational Educators beginning July 1, 2021, educators applying for their first Professional Vocational license or certain Initial Vocational Administrator licenses (specifically Vocational Principal/Assistant Principal and Vocational Supervisor/Director) must obtain the SEI endorsement. 

Academic Administrators (principal/assistant principal or supervisor/director only) can take the Massachusetts SEI Administrator Endorsement Course.

MATSOL SEI courses are taught by highly qualified and experienced instructors of English Learners in Massachusetts public schools who are trained and approved by the Massachusetts Department of Elementary and Secondary Education.
