Some military students at the University of Colorado at Colorado Springs say they have suffered academic or financial penalties when they are deployed.
They say some have not been allowed to make up classwork or get failing grades or are forced to drop classes, which in some cases has meant repayment of financial aid and the loss of GI Bill assistance.
Now the students are petitioning for a policy to protect military students.
About 500 students are active-duty military.
Vice Chancellor Jim Henderson says he e-mails professors each year urging them to accommodate students called to military duty.
The school also is establishing an office this fall to handle issues for active military, veterans and family members.
