The general deadline for applying for a DIP or sabbatical for the following year is the start of October of the year before your sabbatical.
Please note: faculty returning from sabbatical or DIP leaves are required to submit a report on their leave activities within 3 months after resumption of active duty. As you know, the College Deans have been delegated the authority to acknowledge receipt of the leave reports. We are asking for your help in reminding faculty of this requirement upon return from their leaves. The leave report guidelines and submission requirement are available on the APS website.
