I don't have access to the Green Book, so I could really use some help from someone who does. I need to know what the exact policy is on bids being valid for a year. We had a girl receive a bid last fall but she was unable to accept it due to school and family problems. Is her bid only valid for last fall and the spring (one academic year)? Or would it be valid from the date she received it (one full year)? Or is it valid from last fall to this fall, regardless of the exact date?
