If your academic standing is currently Probationary or Deficient, a set of guidelines controls your re-admittance to the university. If you have questions about these guidelines, ask your advisor.
The full manual for the Student Academic Regulations can be found here, but it's a little lengthy, to say the least. Here are some common questions students struggling academically may have:
A student is placed on scholastic probation if his/her current semester or cumulative GPA is less than 2.000. If the cumulative GPA is less than 2.000 and the current semester GPA is above 2.200, the student will not be placed on probation. A student on probation is restricted to 13 credit hours and may not hold office in any organization. He/she is not required to resign from organizations in which he/she is already a member, but he/she may not pledge, be initiated into, or join any other organization. Appeals related to that part of the regulations concerning holding an office in student organizations may be initiated in the Student Activities Office. Failure to submit the completed appeal form within 10 school days following notification of the probationary status by the Student Activities Office will result in automatic denial of the appeal.
A student is considered to be scholastically deficient if he/she has two or more semesters of scholastic probation. Also, he/she is immediately considered scholastically deficient at the end of any semester in which he/she has one or more "Unsatisfactory" or "F" grades and no grade higher than a "D". The student’s records will be referred to his/her academic department for a decision on continued enrollment at S&T, with the results forwarded to the student by the Office of the Registrar. Students can appeal denied enrollment by the department to the provost. Students that have pre-registered and paid fees will be allowed to keep their schedule, with appropriate modifications, if readmitted to the University.
When a grade of “D” or “F” is received in an S&T course, the grade may be replaced in the calculation of the GPA if the course is repeated at S&T. No more than 15 semester hours will be dropped from the calculation of the student’s GPA and a repeated course may only be used to replace one previous grade in that same course in the GPA calculation. Grades of “Incomplete”, “Withdrawn”, “Hearer” or “Pass/Fail” will not replace the previous grade. All grades earned will appear on the student’s transcript. A statement of the repeat policy will be included on the transcript to explain the calculation of the GPA. After repeating a course, the student must submit a Repeat Course GPA Adjustment form to the Registrar’s Office to have the GPA changed. The new grade will replace the old grade in all GPA calculations in which the previous grade was used, with the exception of the UM GPA used for the calculation of graduation honors. If a student does not submit the Repeat Course GPA Adjustment, both grades will be used in GPA calculations. The scholastic standing of a student for the past semester will not be changed as a result of repeating a course. This policy applies to undergraduate students only and may not be applied once the student has graduated.
In order to receive a bachelor's degree, the student must have a cumulative grade point average of at least 2.000. All courses and grades from other institutions are shown on the S&T transcript and used in the calculation of the cumulative GPA. All students transferring to S&T must achieve a cumulative GPA of at least 2.000 in courses taken at S&T for graduation. In order to graduate, students must achieve a cumulative grade point average of 2.000 in courses taken in their major department. In departments that offer more than one major, the 2.000 must be in the major discipline within that department.
No courses can be dropped in the last 3 weeks of class or during finals week. No transcript record is made if the course is dropped within the first 6 weeks; a "WD" is posted on the transcript if dropped after 6 weeks.
Students are required to pay full fees for classes in which they register as “hearer.” None of the work will be graded and the student is not entitled to credit in the course. The student is required to attend class and may receive a “WD” grade if attendance is not to the satisfaction of the instructor of the class. The course credit will be included in all certifications of enrollment. Hearer status must be declared prior to the end of 6-weeks of class.
