Here is the design for the SCMS PBIS shirt. This year's shirt is dark gray and will have the "Proud to be A Mustang" on the front. Last year's shirts will also be available for purchase in blue, black and light gray. Both versions of the shirt can be purchased for $10 cash in the SCMS Cafeteria Mustang Mall and can be worn any day. On special days, ​students wearing a PBIS shirt get special treats!
