Student Support


Office Hours

Office Hours is one of ERHS' primary supports campus-wide to provide students intervention and/or enrichment in all subject matter on Thursdays and Fridays every week. This is built into all 9th-12th grade students' schedules. 

Office hours is a 30 minute time block on Thursdays and Fridays 10:26-10:56 (during a typical schedule). Teachers utilize office hours to tutor, offer test retakes, offer study hall, etc. This is a time for students to go to the class they need the most support in. Students should only go to a class on their schedule.


  • Choose your OH classes earlier in the week so you know where you are going ahead of time
  • Get to class early in case the class reaches capacity
  • Pick the class that you are struggling the most in
  • Stick with it. Go to that class for a month till you see improvement
  • Utilize this time to get your work done or get the help you need - you are in control of your future

ERHS/eSTEM Counselors also offer office hours academic, college/career, and social-emotional workshops.
