Learn about maintaining your SDO certification

Once certified by OSD's Supplier Diversity Office, your certification must be renewed every three years.

RENEWAL – Every three years

SDO certifications automatically expire three years from the date indicated in the certification letter, unless the certification is renewed or recertified on or before that date.  Each company receives a reminder letter 30 days prior to the expiration date.  The items that need to be submitted for renewal will be indicated in the reminder letter.


Certified companies that wish to remain certified must undergo a substantive review of their certification status with an SDO certification specialist who will re-evaluate the company to determine whether it continues to meet the applicable certification criteria. You will be notified when your company becomes due for substantive review.  You will need to submit the applicable recertification application and all required information and documentation to the SDO no later than forty-five (45) business days prior to the date of certification expiration (i.e., the recertification date). At that time, a certification specialist will be assigned to evaluate your company and will make a report and recommendation to the Certification Committee (CC) advising if your company continues to meet the applicable certification criteria.

CHANGES IN CIRCUMSTANCE (structure, ownership, control )

You have a continuing responsibility to notify OSD's Supplier Diversity Office of a change in any information that is relevant to your company's certification eligibility and to ensure that the information and documentation relied upon by SDO to certify or to maintain the certification of your business enterprise is accurate, complete, and not misleading. You are required to notify SDO’s Director of Certification in writing of any change of such information or documentation within 30 calendar days of the change. By way of example and not limitation, any change in ownership, control, ongoing, or independence may be considered material. Failure to abide by the continuing duty requirements shall constitute grounds for the business entity’s decertification.


If you no longer wish to remain certified or your company no longer is in business, you must submit a written notification indicating that you would like the certification to be withdrawn.  

Send request to:
Joyce Kwong
OSD's Supplier Diversity Office
One Ashburton Place, Room 1017
Boston, MA 02108


If your business has been decertified for more than one year, you must reapply for certification.  The first step in re-applying is to attend the pre-certification workshop (if your business is headquartered in the Commonwealth of Massachusetts).  If you are an out-of-state applicant you must view the Webcast.

If your company has been decertified for less than one year, send a written request to reopen the certification to:
Joyce Kwong
OSD's Supplier Diversity Office
One Ashburton Place, Room 1017
Boston, MA 02108


The contact information listed in SDO’s Directory of Certified Businesses is updated daily and must have accurate information. If you need to update any of the contact information, i.e. telephone, fax, email, or website address, a request may be sent by email to: Joyce Kwong at joyce.kwong@mass.gov.


If the legal name or address of the company has changed, you must submit a written request on the company’s letterhead, which has been signed by the owner(s) of the company, along with a new W9 and Terms and Conditions form to:

Joyce Kwong
OSD's Supplier Diversity Office
One Ashburton Place, Room 1017
Boston, MA 02108


To update your current certified description, you must request the change in writing. The request should include the current description and the new description being requested. Requests may be sent via email to Joyce Kwong at joyce.kwong@mass.gov. Once the request is received, the file will be placed in queue for assignment to an investigator for further review.


If your company has both State and Federal Certifications, you are required to submit information for both entities when renewing your certification, as each certification must have its own original set of information (although some of the information may be duplicate).


All personal or business tax returns submitted must be complete, signed copies that include all schedules and attachments.  If you file a joint tax return with your spouse, you may remove/erase the social security number of the non-certified person.
