The TF Program is a specialized program in which graduate students employed as TFs ultimately obtain a certificate of completion. This is achieved by engaging in a series of steps, including creating a Teaching Portfolio, receiving evaluations from the course instructor, and undergoing a review of the Teaching Portfolio. This program ensures that these TFs have fulfilled the role of a TF as a step towards becoming university instructors. Hiroshima University guarantees the successful completion of this program and aims to provide evidence of this experience and accomplishment as a valuable asset for their future careers.
