Each college limits the number of credits you can transfer in from another college. This limit is generally around 70 credits, but each school has the right to set its own limits. Each credit transferred into your new school has a GPA value for the completed class. These transferred credits become part of your new GPA at your new school. So, while your GPA does not follow you to your new school, you can choose not to transfer classes where you scored poorly, and classes where you scored too low for the class to count as completed are not transferable.
Institutional GPA is a calculation of your academic performance at a college. This only includes the classes you took at the school. Colleges will request a copy of your institutional GPA, along with your transcript information for former schools, to determine if they are willing to admit you to the new school. While your institutional GPA, from former schools, does not transfer into your new school, it has an impact on whether other schools accept you.
Along with your institutional GPA, graduate and doctoral programs review your departmental GPA. Your departmental GPA is a record of grades from all courses you have taken within a specific academic field. Your departmental GPA represents your proficiency in your primary field of study. While you departmental GPA, from former schools, does not transfer into your new school, it has a strong impact on whether colleges accept you (most notably into graduate or doctorate specialty programs).
When you complete a degree, the school factors your final GPA for the degree plan you chose. This includes all classes that counted towards your final degree plan. Once you complete your degree, your final GPA will never change, even if you retake classes where you scored poorly. While your degree GPA does not carry over into future degrees, you can include classes from your completed degree in degree plans for an additional degree. The school you wish to transfer to reviews your degree GPA alongside your departmental GPA when it determines whether to admit you into a higher (graduate or doctorate) program.
