The transcript type field denotes whether the incoming document is a college, high school, or military transcript. The field result is determined by the system automatically, based on the classification results. The field is presented as read-only within Verifier and can only be changed by reclassification of the document.
In order to eliminate chances of mis-classification by the automated classification process, you can pre-define the document type using standardized auto-index values in the document file-name.
