What is it with the word test?

We begin our yearly testing program today with a mental ability test followed next week by an achievement test. Shouldn't be a big deal-our kids always do an extremely good job on standardized tests. This being said, quite a few freaked out yesterday when I reminded them to bring a #2 pencil. A few even asked what they needed to study and weren't relieved after being told that they can't study for this kind of test--AND--these are 8th graders who have taken the same kind of test at least 6 years now! I hate to see them stressing over these things as much as they are. Now, if only they would stress a little over their personal narrative that is due in a week...
