SEI Endorsement Center

DESE has designated the Collaborative for Educational Services as an approved SEI Endorsement Center offering for-cost Sheltered English Instruction (SEI) courses for teachers and administrators. 


What is the SEI Endorsement?

Closing the proficiency gap depends on teachers having the skills and knowledge necessary to instruct English Language Learners (ELLs). Sheltered English Immersion (SEI) is an approach to teaching academic content in English to ELLs. Generally, but not always, ELLs are in the same classrooms as native English-speaking students. To better serve these students, core academic teachers, vocational teachers and those administrators who supervise and evaluate core academic teachers are required to obtain an SEI teacher or SEI administrator endorsement.

While core academic teachers are required to earn the SEI Endorsement, all licensed teachers interested in strengthening their skills working with ELs who have access to students in a classroom may enroll in an SEI Endorsement course. Similarly, administrators other than those described above may enroll in the teacher or administrator SEI Endorsement courses.

CES offers SEI Endorsement open enrollment courses, but will also bring the SEI Endorsement course on-site to you at your school or district. Due to DESE restrictions, SEI courses are only offered during the school year.  

Who must earn the SEI Endorsement?

As of July 1, 2014, educators applying for their first Initial license (specifically core academic teachers of ELLs and principals/assistant principals and supervisors/directors who supervise or evaluate such teachers) must obtain the SEI endorsement.

  • 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
  • Academic Administrators – principal/assistant principal or supervisor/director only
  • Vocational Educatorsbeginning 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.

As of July 1, 2016, school districts must ensure that ELLs are assigned to core academic teachers who have obtained the SEI Endorsement, or are required to obtain the Endorsement within a year of the assignment.

Starting July 1, 2021, school districts must ensure that ELLs in Chapter 74 Vocational programs are assigned to teachers who have obtained the SEI Endorsement. If an ELL is assigned to a teacher without the endorsement, the teacher is required to obtain the endorsement within a year of assignment.
