Fill out a copy of your new university's transfer credit approval form before taking a class at another school. These forms are specifically intended for study abroad and short term sabbatical leave students who already know they intend to return to their home university but will be accumulating credits elsewhere for a short time. Obtain these documents from your admissions department, and have them signed by the professor approving the credit exchange.
Obtain a copy of the transcript from your first university, which contains the grades for the classes you would like to transfer to your new university. Ask the school to send an official transcript copy on university letterhead to your new school. Direct the letter to the head of your new school's admission's department unless your new university has a department specifically dedicated to transfer credits.
Read your school's guidelines on credit transfers carefully before choosing which units you want to transfer. Schools with particular departmental focuses, such as engineering or liberal arts, may have more stringent requirements about the content of their courses in order to approve the credits.
Submit a credit transfer requests using the necessary forms provided by your new university. Pay close attention to any credit deadlines which may exist. Wait for an official letter back from your school pertaining to which credits they will accept. Note that most schools accept credits only when a grade of C or better is achieved.
File an appeal with your school's admissions department or request an in-person evaluation of the credits in which you can defend the correlation between credits taken elsewhere and the classes offered at your new school. Use a course catalog from both colleges to defend the simiilarities in course content, including number of hours of class per week, evaluation methods and course material.
