* The specific Missouri university: Each university has its own credit transfer policies. Some are more accepting of credits from for-profit institutions like the University of Phoenix than others. You'll need to contact the admissions office of the *specific* Missouri university you're interested in attending.
* The courses you took at University of Phoenix: The university will evaluate your transcripts to determine which courses align with their curriculum and meet their requirements. They may not accept all credits. Courses that are too general, lack sufficient rigor, or don't match the Missouri university's program requirements are likely to be rejected.
* Your intended major: The transferability of credits often depends heavily on your major. Credits from a general education course might transfer, while specialized courses may not.
* University of Phoenix accreditation: While the University of Phoenix is regionally accredited, the specific accreditation and its acceptance varies from institution to institution.
In short: You *might* be able to transfer some credits, but you must contact the admissions office of each Missouri university you are considering to find out their specific transfer policies and whether your credits will transfer. Don't assume any credits will transfer until you have official confirmation from the university.
