Students admitted to Trinity College are subject to the program requirements of the Catalog current at the time of initial enrollment (matriculation). The Trinity College catalog is valid for seven years for those students who enter under that catalog and enroll continuously. If courses from that catalog are no longer offered, course substitutions approved by the program director can be used to fulfill requirements.  
Students may elect, by indicating their intention to the Academic Records Office, to complete the program requirements of a subsequent catalog. However, the catalog change policy requires that students complete all degree requirements under any subsequent catalog selected. Students must choose one catalog or the other, not a combination of the two. 
If a student withdraws and is readmitted, the student is subject to the program requirements current at the time of re-enrollment.
