Reading tests at grades 4, 8, and 10 contain passages taken from magazines, books, and other publications that students are expected to be able to read at their grade level. Reading selections are reproduced in the test books along with the kinds of pictures, captions, and graphics that are typically a part of published passages. Passage length varies from an average of about 400 words at grade 4 to an average of about 900 words at grade 10. Individual passages at grade 4 may be as long as 900 words and at tenth grade nearly twice as long.
