Disability Accommodations:
Students needing academic accommodations for a disability must first
register with Disability Accommodations & Success Strategies (DASS).
Students can call 2147681470 or visit http://www.smu.edu/Provost/ALEC/DASS to
begin the process. Once registered, students should then schedule an
appointment with the professor as early in the semester as possible, present a
DASS Accommodation Letter, and make appropriate arrangements. Please note
that accommodations are not retroactive and require advance notice to implement.
·
Religious Observance: Religiously observant students wishing to be absent on
holidays that require missing class should notify their professors in writing
at the beginning of the semester, and should discuss with them, in advance,
acceptable ways of making up any work missed because of the absence. (See
University Policy No. 1.9.)
·
Excused Absences for
University Extracurricular Activities:
Students participating in an officially sanctioned, scheduled University
extracurricular activity should be given the opportunity to make up class
assignments or other graded assignments missed as a result of their
participation. It is the responsibility of the student to make
arrangements with the instructor prior to any missed scheduled examination or
other missed assignment for making up the work. (University Undergraduate
Catalogue)
·
Final Exams: Final course examinations shall be given in all
courses where they are appropriate, and some form of final assessment is
essential. Final exams or final assessments must be administered as
specified in the official examination schedule, and shall not be administered
during the last week of classes or during the Reading Period. Please
state clearly in the syllabus the date/time and form of the final exam or
assessment.
