Academics and Registration

The Office of the Registrar and Registration manages student registration and student records, including issuing University transcripts. Part of the Flyers First complex, it is located on the 4th floor of St. Mary's Hall. As a University of Dayton student, you will use the University's Web portal, Porches, to register for classes, change your class schedule, and access important course information. 

Registering for Classes

Returning undergraduate and graduate students can register online on Porches. Registration instructions for currently enrolled undergraduate and graduate students can be found here

If you are a student in the Intensive English Program, you will be registered for classes by the IEP staff and teachers. Exchange students can contact the 937-229-3728 for assistance in registering for classes.

Academic Catalog

The University Academic Catalog has a comprehensive list of course descriptions, requirements for each undergraduate major and other important details related to your academic success.

Adding or Dropping a Class

If you need to add or drop a class prior to the start of the semester, you may do so on Porches. Once classes have started, you will need to complete a drop/add form and bring it to St. Mary’s Hall, room 411. However, if dropping a class results in your enrollment being less than full time, you must first contact the ISSS office for more information. (Full-time enrollment is generally defined as 12 credit hours for undergraduates and six or nine credit hours for graduates depending on the program. Contact the ISSS office for specific information.)

Withdrawing from the University

If you must withdraw from the University (thus dropping all of your classes), please contact the ISSS office for more information on the proper procedure. 

Credit Hours

A credit hour is one unit of academic credit. Each credit is usually equivalent to one hour per week of class time. Many classes at the University of Dayton are three credit hours, although some are as few as one and as many as four. Undergraduate class levels are computed using total completed hours. This also includes transfer hours accepted towards a degree. Undergraduate levels are determined as follows:

Number of Credit Hours Undergraduate Level
0-29.9 Freshman/first-year
30-59.9 Sophomore
60-89.9 Junior
90 and above Senior


Undergraduate students must complete 123 or more credit hours to graduate, depending on the program of study. Graduate students must complete 30 or more credit hours to graduate, depending on the program (levels do not pertain to graduate students).

Grading Scale and Grade Point Average (GPA)

The most frequently used grading scale at the University of Dayton is the letter grade scale. Letters are used and translated into grade points based on the following system:

Letter Grade Grade Point Equivalent
A 4.0
A- 3.67
B+ 3.33
B 3.0
B- 2.67
C+ 2.33
C- 1.67
D 1.0
F 0


The grade point average or GPA is determined by dividing the total number of grade points earned by the total number of credit hours attempted. The GPA may range from 0.0 to a 4.0, with 4.0 being the highest level of achievement.

In general, undergraduate students must have a minimum GPA of 2.0 to graduate; however, the required GPA is higher for some academic programs. In most programs, graduate students must have a minimum GPA of 3.0 to graduate. In order to maintain most undergraduate scholarships and graduate assistantships, students must maintain a 3.0 GPA.
