Adding cross-endorsements to Connecticut teaching certificates

The first step to adding an endorsement to your educator certificate is to complete an online application or paper-based ED 170 application.

Mail the paper-based application, review fee (if applicable), official transcripts, and test results for any corresponding assessments to the address on the top of the form.


Most endorsements require specific course work in the subject area. Learn more and see the requirements for each endorsement.


If you complete your renewal application online, you can submit your payment by credit card.

If you choose to mail your application, acceptable payment forms (money order, cashier’s check, or certified bank check) and the mailing address are located at the top of the form.

The total cost for each additional endorsement is $100, including the $50 nonrefundable review fee.

Important Note: Emailed or faxed paper-based applications and forms with signatures cannot be accepted. The original versions must be mailed.


Please allow approximately 2-3 months for processing after submitting your application. Once all required documentation has been received, determination of eligibility may take several months. All applications are processed in the order by which they were submitted.  

Due to the large volume of e-transcripts received, e-transcripts may expire before the file is reviewed. If possible, please submit a paper-based official transcript in the sealed envelope to avoid delays.
