Consider adding the Credentialing Information to Courses (CRS). If districts maintain the creditialing information in STC, the credential field values are linked in CRS. When a course is added to the master schedule, produce a report that shows the credential needed and the credential that the assigned teacher has. The report could also display anomalies. This would allow districts the opportunity to monitor and remedy any credentialing issues early in the school year - long before Fall 2.
