Do I need to keep my high school transcripts? I graduated high school in the United States and I have a bachelors degree from an accredited university in the United States as well.  Would I need to keep my high school transcripts for any purpose?  For example, Grad school in the US or abroad or any other need?
Grad school applications typically only want your undergraduate transcript since that is your highest level of education (and most recent). This is the system in Canada, and I can't think of a reason it would be different in the US.
