For-profit firms with their principal place of business in Massachusetts must take SDO's Instructor-led Pre-Certification Session BEFORE completing the online application. Out of state for-profit firms must take the online Pre-Certification Webcast and non-profit firms must take the online Pre-Certification Workshop designed for non-profit applicants. WBENC, GNEMSDC, VetBiz, NGLCC, and USBLN certified firms must visit the SDO website for further application instructions.

Note: Use the online application for SDO certifications (MBE, WBE, PBE and VBE) only. If you are applying for Disadvantaged Business Enterprise (DBE) certification for transportation agencies, please download the Uniform Certification Application, Affidavit of Certification, and the Personal Financial Statement from the Unified Certification Program's website.

Please remember to print out, sign, and notarize your completed applications. Applications submitted without all supporting documents will not be processed.
