The four-week testing window for CLT3-8 means that the exams can be administered to testers on any day(s) during this period.
The CLT3, CLT4, CLT5, and CLT6 are intended for 3rd-6th grade, respectively, and have recommended timing, with expected completion in two to three hours. The four sections on each exam can be split up and administered over the course of several days, if desired. Individual sections must be completed in one sitting and the entire test must be completed within two weeks of beginning it.
CLT7 and CLT8 have required timing and the entire test must be completed in one sitting. Both exams contain three sections and must be completed in one sitting of 135 minutes, with a short break between sections 2&3.
Before the testing window, your school’s test manager will receive instructions to log in to an online account where the test(s) can be accessed. For each exam you have purchased, you will receive a test access code which your testers will use to access the online exam. This access code may be used once per student and will expire at the end of the testing window.
If you have purchased multiple tests–for example, one CLT3 and one CLT5–they do not need to be administered on the same day, as long as each tester tests within the testing window.
