The I.R.A. is an academic index score between 0-10,000 that represents a weighted average of all grades a student has received. It considers the number of credits and semester of each class, with earlier semesters weighted higher. Withdrawn classes are not included in the average, but do reduce the I.R.A. through a withdrawal factor based on the percentage of classes withdrawn from total classes. The more classes completed, the smaller the reduction from withdrawals. The final I.R.A. is this weighted average, adjusted for any withdrawal factor reduction.

How does the I.R.A. formula work?

1
By Prof. André Jalles

 Academic Result Index (I.R.A.)

The I.R.A. is a measure of values between 0 (zero) and 10.000 (ten thousand). Its calculation is possible
following the conclusion of the first classes attended at UFC. The Index represents an average weighted
measurement of all grades a student has obtained throughout the fulfillment of their curriculum. The I.R.A.
calculation only considers grades, not the concept, nor the attendance rate of the student for the activities and there
is no discrimination between mandatory courses and electives or between classes in which the student passed or
failed. The weighted average considers: the number of course credits for the class at the moment it was taken,
combined with the number of semesters that the student has attended university, with a maximum value of 6.
Thus, classes taken in the first semester are attributed the weight of 1; second semester classes receive the
weighted value of 2 and so on until the sixth semester. All classes from the sixth semester on receive the weighted
average of 6 – including the seventh, eighth, etc. For year-long classes the weight follows the same logic, being
attributed according to the semester in which the class starts.

 Policy for withdrawn classes

Withdrawn classes, as they do not have grades, do not take part in the weighted average calculation of the
I.R.A., although there is a reducing factor resulting from the withdraws. This reducing factor is calculated by using
the percentage of the withdrawn classes out of the total amount of classes taken. Therefore, the reduction of the
I.R.A. is larger for students that have taken a smaller number of classes, and is slowly reduced with the more
courses completed. Here are two cases as an example: in the first case, a student withdraws from a class in the first
semester, from a course load of five classes. This student will have his I.R.A. calculated in the end of his first
semester based on 90% of the grades obtained in the 4 classes that he managed to finish. In our second example, a
student in the eighth semester of university makes his first withdraw. In this case, if the student has already
attended a total of 39 classes including courses from the eighth semester, he will have his I.R.A. calculated at the
end of his eighth semester using 98.75% of the average of all his grades obtained in the 39 classes he attended.
This is his final weighted average, calculated based on the credits attributed to courses, and adding the semester in
which they were attended.

I.R.A. Formula

In which:

Dt = Number of withdrawn classes;


Dc= Total number of attended classes (including the number of withdraws and failed classes);
Pi = Final grade in the class "i";
Cri= Number of credits for the class "i";
Pei= Semester in which class "i" was attended, following the limitation:
Pei = minimum{6, semester in which the class was attended}.
