Content Level Indicators: Content level icons indicate that a resource falls within a specific Lexile measure range. If no Lexile measure is available, the icon represents the appropriate target audience. There are five Content levels, Level One through Level Five, which correspond to the following Lexile measures or audience values:

1. Level One: Lexile measure less than 500L; also represents lower elementary content
2. Level Two: Lexile measure of 501L-850L; also represents upper elementary content
3. Level Three: Lexile measure of 851L-1100L; also represents middle school content
4. Level Four: Lexile measure of 1101L-1300L; also represents high school or general audience content
5. Level Five: Lexile measure of 1301L and up; also represents academic or advanced content

This setting enables both the display of content levels in search results and the ability to limit a search by content level. Only select products support content level indicators and to use this feature you must enable it through Product Specific Preferences.

Lexile measures: A system that rates the difficulty of text based on word frequency and sentence length. A score is displayed as a number followed by an L, such as 850L. The reading level assigns a category to a range of scores. For example, scores below 200L are considered beginning-reader material, while scores above 1700L are considered advanced (i.e., at the college level).

This setting enables both the display of Lexile measures in search results and document pages and the ability to limit a search by Lexile measure. Only select products support Lexile measures and to use this feature you must enable it through Product Specific Preferences.
