MDAC Wheel

In the seventh and eighth grade students participate in specialized studies in Music, Drama, Art, and Community Service in a quarterly structure called the MDAC wheel.  During these classes students are given the ability to choose from a group of topics which one they will focus on learning more in depth.  As a result of this, specific benchmarks are not listed here and vary for each student.
