Notes: Students in grades 3-8 took a shorter version of the tests in spring 2021. Item results are not reported if fewer than 10 students in the school or district answered the item.

Participation rates varied across schools, districts, and student groups in 2021 more than in prior years. If the participation rate in 2021 was lower than in prior years, results may have been different if more students had taken the test.
