UH officially extends interim grading policy through spring UH has officially extended the interim grading policy through the end of Spring 2021, Provost Paula Myrick Short said in an email to the University community on Thursday morning. After setbacks from the winter storm and the ongoing pandemic, Short decided it would be in the best interest of the students to bring back the pass/fail grading system, which will work the same as in past semesters. Once students receive their end of semester grades, they will have the option to choose between pass/fail grading or the standard letter grading for their qualifying grades.
