SEI Endorsement Center

Providing SEI Endorsement Courses Statewide

ESE has designated the Collaborative for Educational Services (CES) as an approved SEI Endorsement Center offering for-cost Sheltered English Instruction (SEI) courses for teachers and administrators, including the full teacher course and administrator courses.  

CES offers open enrollment courses, but will also bring the SEI endorsement course on-site to you at your school or district.

SEI Endorsement Center course delivery of the Full Face-to-Face Teacher Course includes 12 face-to-face sessions, a capstone project presentation, online work between sessions, and three make-up sessions. The Full Face-to-Face course offered through CES will utilize exactly the same curricula utilized in ESE-sponsored no-cost trainings; and facilitators have been screened and trained by ESE and are held to the same high expectations for course delivery. Participants must have daily access to students in a classroom during the semester the course is taken. 

This SEI Teacher Course equips participants with strategies to support ELLs' access to content instruction through evidence-based reading, writing and vocabulary interventions. Anyone who satisfactorily completes this course will be eligible for the SEI Teacher Endorsement.

Are you an administrator interested in purchasing a course to offer to teachers in your district who need the SEI Endorsement?

We have worked with districts like Holliston and Lawrence, and Fall River. Contact Suzanne Judson-Whitehouse,, to discuss a site-based SEI Endorsement course in your district! 

Frequently Asked Questions

Q1: Who must earn the SEI Endorsement?

A1: Core academic teachers must earn the SEI Teacher Endorsement. The following teachers are core academic teachers for the purposes of providing SEI instruction: teachers of students with moderate disabilities; teachers of students with severe disabilities; subject-area teachers in English, reading or language arts, mathematics, science, civics and government, economics, history and geography; and early childhood and elementary teachers who teach such content.

If you are a principal/assistant principal or supervisor/director who supervises or evaluates one or more core academic teachers, you must earn the SEI Administrator Endorsement.

While core academic teachers are required to earn the SEI Endorsement, all licensed teachers interested in strengthening their skills working with ELLs 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.

Q2: Which SEI Endorsement courses does CES offer?

A2: CES offers both teacher and administrator SEI Endorsement courses, depending on interest and instructor availability. Please contact Karen Rehmus for more information.

Q3: How often does CES offer open-enrollment SEI Endorsement courses?

A3: Courses are offered throughout the school year. Due to ESE restrictions, SEI courses are not offered outside of the school year.
