Block-End Notes About the PowerSchool Portal

The Parent/Student Portal is a real-time system, which means that assignment grades are visible as soon as they are entered by a teacher. This has several advantages and a few disadvantages. I want to outline the disadvantages so that all users have a clear idea of the limits of the site:

  1. Grades on the site are subject to change and not to be considered official.
  2. Cumulative grades may be misleading before the grading term is closed. This can be due to assignment weighting and calculation configurations that aren’t visible on the site.
  3. Block and semester grades should not be considered accurate at the end date of the term. There is a grading period of approximately a week between the last day of a term and the close of grades for that term. This gives teachers time to thoughtfully complete grades for assignments that fell toward the end of the term.
