Seniors will be required to take the Illinois Science Assessment (ISA) on Tuesday, Oct. 5.

The test has three sections and is not timed; the average student takes about 150 minutes to complete it.

Students will be excused from periods 1-4 or 6-9 to take the test and seniors will be notified which block they are in one week before the test. They will also need to bring fully-charged Chromebooks as the test will be taken online.
