KK,

To this point, all that you have presented would not require anything
more sophisticated than a simple chi-square test that could be
obtained through PROC FREQ.  However, I have a feeling that there is
more to the story than you have presented, such as how the data are
collected and whether or not students are clustered in classrooms.
Before any advice can be provided, you need to give a more thorough
description of your data.
