AP is a type of dual credit, but there are other types that have become very popular in the last decade.Dual credits as in AP classes, or are they something different?
Many dual credits now come through a local community college. In this case dual credit courses are taught by a high school teacher during the school day through these local community colleges. Some universities (SLU and EIU for example) also do this. Most of these high school teachers need to have a Masters degree in the area of instruction.
Another type of dual credit is that some high schools allow their students to physically attend a community college during the school day. These are also considered dual credit.
A dual credit earned by a student counts for both high school and college credit. When a student graduates from high school and is accepted at a college/university the institution determine if the credits will be allowed to transfer. UofI has accepted everyone of my kids dual credits. They have come from EIU, SLU, Lincoln Land CC and Lake Land CC. I hope that makes sense.
