It means the State of Missouri has reviewed a business and confirmed that it is owned and controlled by a minority owner. The Missouri Office of Equal Opportunity (OEO) runs the MBE/WBE program for minority- and woman-owned businesses. A certified firm gets a certificate and a listing in the state’s vendor directory. For a prime contractor, that listing is a way to find and check a possible partner. Read the [MBE](https://aes.multisites.ai/glossary/mbe-minority-business-enterprise) glossary entry for the short definition. Certification is a status, not a trade license. It says nothing about what the firm builds, and it does not replace permits, registrations or training that a trade requires. ## Who qualifies under OEO’s rules? A firm must pass three tests, as written by OEO. Test OEO wording Ownership At least 51% owned by a minority and/or woman who is a U.S. citizen or lawfully admitted permanent resident Control The owner holds the highest position and can exercise direct control over daily and long-term decisions on management, policy and operations Structure Organized as a for-profit business The control test matters as much as the ownership test. OEO requires the owner to hold the highest position and direct the business. A prime can keep that in mind when it screens partners. ## How does a business get certified? By application, document review and a site visit. OEO describes this order: 1. Take the self-assessment on the “Am I Ready to Apply?” page. 2. Register for a MoLogin account. 3. Start the initial application and upload the supporting documents. 4. Wait for a specialist to review it. OEO may email you for more information. 5. Host an onsite visit with the owners. OEO says it “typically lasts between 15 and 30 minutes.” 6. Receive the certification decision. If approved, you get an email with a certificate and a listing in the vendor directory. ## How does a firm keep its certification? By updating every year. OEO says “a yearly update is required to maintain certification.” Reminder emails go out 60 and 30 days before the due date. The annual update lists any changes in the last year. Recertification asks for proof of good standing with the Missouri Secretary of State, the last 3 years of federal business tax returns, and a notarized recertification affidavit. Because of the yearly update, a prime should ask each firm for current paperwork and check the state directory. ## What should a prime contractor check before counting an MBE? Start with the project’s own bid documents. Every owner sets its own goals and rules for how minority participation counts, and those documents control. Then check the firm itself: 1. Is it listed in the OEO MBE/WBE Vendor Directory? 2. Is its certificate current, with the annual update done? 3. Does it hold the trade registrations the work needs? For asbestos work in Missouri, that includes DNR registration, certified workers and a certified inspector’s [asbestos survey](https://aes.multisites.ai/glossary/asbestos-survey). For lead work, Missouri’s DHSS licenses the professionals and the company; see [lead abatement](https://aes.multisites.ai/glossary/lead-abatement). 4. Can it do the scope you plan to give it? Our guide to [MBE contractors on Missouri projects](https://aes.multisites.ai/guides/mbe-contractors-on-missouri-projects) goes into bid practice, and our [MBE and government contractor](https://aes.multisites.ai/mbe-government-contractor) page covers AES. ## Why does this matter on public and large private projects? Many public owners and some large private owners set goals for minority business participation on their projects. We cannot tell you the goal on your project, because each owner writes its own. Read the bid documents, ask the owner or program office how participation is counted, and get that answer in writing before you build a bid around an MBE partner. A certified MBE that is also properly registered for the trade work is the safest kind of partner. A firm that holds only the certificate may not be allowed to do the work. A firm that holds only the trade license may not count toward a goal. Ask for both. ## What does Advanced Environmental Services say about its status? AES describes itself as “a minority-owned business” and “A Native American Company,” with the title “Minority Business Enterprise (MBE)” on its site. It is also a Union Signatory Contractor and serves residential, commercial, industrial, governmental and healthcare customers. See our [about page](https://aes.multisites.ai/about) for the company background. ## Next step If you are a prime contractor or public owner who needs [asbestos abatement](https://aes.multisites.ai/asbestos-abatement), demolition, mold or PFAS work from a minority-owned firm, read our [MBE and government contractor](https://aes.multisites.ai/mbe-government-contractor) page.

At least 51%. Missouri's Office of Equal Opportunity says the business must be at least 51% owned by a minority and/or woman who is a U.S. citizen or lawfully admitted permanent resident. That owner must also hold the highest position and control daily and long-term decisions. ### How often must an MBE renew its certification? Every year. OEO requires a yearly update to keep the certification and sends reminder emails 60 and 30 days before the due date. The update lists any changes in the last year. Recertification needs good standing papers, three years of tax returns and a notarized affidavit. ### Where can a prime contractor find certified MBE firms in Missouri? In the state's MBE/WBE Vendor Directory. OEO says certified vendors are listed there after approval. The directory is on the OEO site under Certified Vendors. Check a firm's listing and dates before you count it on a bid. ## Terms on this page - [MBE (Minority Business Enterprise)](https://aes.multisites.ai/glossary/mbe-minority-business-enterprise) - [Asbestos survey](https://aes.multisites.ai/glossary/asbestos-survey) - [Lead abatement](https://aes.multisites.ai/glossary/lead-abatement) - [PFAS](https://aes.multisites.ai/glossary/pfas) ## Sources 1.
