You must pass the Missouri Content Assessment (MoCA) in order to be certified to teach in the state of Missouri. The MoCA is a DESE requirement and cannot be waived. This assessment documents subject matter competence; therefore, the appropriate content test must be passed prior to your supervised teaching (SEC 784).
More information regarding the MoCA can be found at the following links:
Your undergraduate coursework in the subject matter area should have prepared you for the MoCA, however, preparation materials are available for all subject areas.
