If you find out that another teacher is giving a huge test the same day you are...?
Do you move your test to another day?
I tested my Geometry kids on Friday, and they complained that there was a bio test the same day. (Most of the kids in my Honors Geometry class are also in Honors Biology.) I considered moving the test to Monday, but I had planned an activity for before break, so I wanted to get the test out of the way.
My school has a test postponement policy, which states that if a student has 2 or more tests, quizzes, papers, or projects due on the same day, they can move one of them. I just finished grading them, and the grades look alright, but not as good as usual. The median is around an 82, while it's usually an 85.
What happens during finals? At my son's high school they have 3 finals one day & 2 the next. It's worked out that he's had 2 hard finals, or even 3 on one day & the rest were easy. He's had 2 honors classes in one tri before with both finals on the same day.
We have 8 periods in a day, and our finals are spread across 4 days. (Period 1 and Period 2 on Monday, Period 3 and 4 on Tuesday, etc.) English finals happen the Friday before to give English teachers more time to grade the essays. So most of our students will have 4 finals spread out over 4 days, but they can have 2 on the same day. But that's expected with finals, and most teachers allow students to move a final up if they want to.
We have school-wide testing days. Math department can only give tests on Tuesdays or Fridays. Each department gets two days, and it is worked out so students can have at most 2 tests per day. Math department shares one test day with the world language department and one with the science department. Kids should be able to deal with 2 tests.
You definitely don't need to feel the need to move the test, they really should be able to handle it. But if you wanted, you could also have allowed them to come in on their own time to take the test early.
