The science tests contain a series of items clustered around a common stimulus. The stimulus material appears on the left side of the screen with the items occurring on the right side. This is the same layout that exists for reading passages and items. Many of the items on the science forms have multiple component parts. As such, these forms require students to dive deeply into the central NGSS that the form is based upon.
The Earth Science, Life Science, and Physical Science domains are all represented at Elementary (Grades 3–5), Middle (Grades 6–8), and High School (Grades 9–12) levels. For more information on the number of forms available by domain, see the Science Forms Table document.
