ISAT Island creating confidence: 'They all support each other' Sixth grade teachers came together at Lewis and Clark Middle School in Meridian to put on a fun "Survivor" inspired activity to prepare students for the ISAT. Author: Tami Tremblay Updated: 11:42 AM MDT May 13, 2021 MERIDIAN, Idaho — The Idaho Student Achievement test, or ISAT, is taken by 6th graders at the end of the school year to help understand they're learning. One teacher team in Meridian put together a fun activity to get their students ready. "We had sat down and talked about what do we want to do to prepare the kids for the test," explained Kayla Kiemel, with Shannon Schwartz. They are both 6th grade English teachers at Lewis and Clark Middle School. "We want them to go in having a positive outlook, not looking at it as being a test to be afraid of, or nervous about, and a chance to just show what they've learned."
