Add/Drop Deadlines and Section Switches

Students may add courses during Pass One, Pass Two, Open Hours, Open Registration, or Schedule Adjustment. The last day to add a course is the 12th day of instruction.

Permission to Add (PTA) & Drop (PTD) Numbers

Instructors may issue students a PTA number to enroll in their course, via Schedule Builder, due to a time conflict or restriction. Departments generate their course's PTA numbers. Each PTA number can be used only one time. If the student is on a wait list of the course in which they have been issued a PTA, the student is able to add the course without having to drop the course from the wait list.

Each PTA number is a unique, randomly-generated four-digit number. A student adding the course via SISWeb enters both the section Course Registration Number (CRN) and the PTA number. Multiple-part courses that do not use the combined schedule (COM) require a PTA number for each part of the course.

Note: The PTA will be revoked after 72 hours from issuance. PTAs issued during the last three days of instruction must be used by the last day of instruction.

Students may drop courses during Pass One, Pass Two, Open Hours, Open Registration, or Schedule Adjustment. The last day to drop a course without dean’s approval is the 10th day of instruction for designated 10-day-drop courses or the 20th day of instruction for all other courses. Students need to obtain the permission of their dean and pay a $3.00 fee to drop a designated 10-day-drop course after the 10th day of instruction or to drop all other courses after the 20th day of instruction.

To drop a course after the deadline, students must follow these steps:

  1. Go to the college Dean's office to request permission to drop a course.
  2. If permission is granted, the college Dean's office will issue a PTD number. The student must then log on to Schedule Builder and drop the course by using the five-digit CRN and the four-digit PTD number. If the student is successful, SISWeb will confirm the drop. A $3.00 fee for the late drop will be charged to the student's account.

Graduate students must submit a Permission to Drop (PTD) Petition (GS316) to Graduate Studies.

Students have three calendar days after the day the dean’s office issues the PTD number in which to use the number. The PTD will be revoked after 72 hours from issuance. PTDs issued during the last three days of instruction must be used by the last day of instruction.

Permission to drop courses after the deadline may be granted only in exceptional circumstances.

Late Drops

At any time after the add deadline and before the close of business on the last day of instruction for the term approval may be granted upon petition by the student and certification by an appropriate authority that, due to unexpected circumstances beyond the student’s control, one or more courses should be dropped. The circumstances may include illness, serious personal problems, an accident, a death in the immediate family, a large and necessary increase in working hours, or other situations deemed to be of equal gravity. The petition must be approved by the appropriate dean and, in addition, by the appropriate committee of the faculty of the student’s college or school or the appropriate subcommittee of the Graduate Council. The faculty committee may authorize an administrative officer to act on its behalf, but at least once each quarter the committee should receive and review a summary of the actions taken in its name. An undergraduate student is permitted to drop a course subsequent to the drop deadline even if doing so would reduce that student’s study list below 12 units, but such a student no longer can be certified as a full-time student.

To add a course after the 12th day of instruction, department approval is required (the deans have delegated the approval of late adds to academic departments), in addition to a $3.00 fee. If the late add is approved, the department will issue the student a PTA number so that the student may add the course using Schedule Builder. These PTAs are effective beginning the 13th day of instruction and late adds with PTA may continue until the last day of instruction. PTAs issued during the last three days of instruction must be used by the last day of instruction. Students wishing to add a course after the deadline will need to submit a Retroactive Change Petition.

Section Switch

Students can switch from one section to another section of the same course by using Schedule Builder.

When making a section switch using Schedule Builder, students must first search for available sections of the class. When they search for classes, the results will display only sections with space available. Students should select the Swap Section/Course function from the registration Action field to drop the old section and register in the desired section of the course.

Note: Students will not be able to use the Swap Section/Course function if the new section choice is closed.

Section Switch after the Drop Deadline

When attempting to switch sections after the drop deadline, students should:

  1. Obtain an Undergraduate Course Change Form.
  2. Obtain department or instructor signature. Take the approved form to the Cashier’s Office, in Dutton Hall, and pay the $3.00 fee.
  3. Take the validated form to the Office of the University Registrar, in 3100 Dutton Hall, during normal business hours (10 a.m.-4 p.m. (PT) weekdays).

After the drop deadline, students should be sure to obtain a change form from the department. If they attempt to complete the section switch with a PTA number after the drop deadline, they will not be able to drop the old section. If they do add the new section with a PTA number after the drop deadline, they must obtain documentation of the error from the department and take it to the Office of the University Registrar to drop the old section.

Please note: Section Switches after the drop and/or add deadline should not be processed by obtaining a PTA or PTD, students should always fill out the Undergraduate Course Change Form and obtain instructor's signature of the desired section.
