Yes, you are still required to complete a Missouri Background Check through the Professional Conduct and Investigations Section. The FBI does not share other state's information with Missouri. The Teacher Certification Section, however, will notify you if you meet the academic requirements for your certificate of license to teach pending approval of the background check.
Many individuals find such letter useful.
The Professional Conduct and Investigations Section will notify you and the Teacher Certification Section of the results of your background check as soon as they are received. DESE may bring charges if the certificate holder has a criminal conviction. A school district may bring charges against a teacher's certificate for incompetency, cruelty, immorality, drunkenness, neglect of duty, or the annulling of a written contract for reasons other than election to the general assembly. In order for you to receive a certificate of license to teach, your application must be brought before and unanimously approved by the State Board of Education. The school district you resign from may file charges seeking disciplinary action against your certificate of license to teach for breaking a written contract.
