What Does MY Reading
Assessment Data say about ME?
Lexile Levels
• A Lexile measure is a valuable piece of
information about either an individual's
reading ability or the difficulty of a text, like a
book or magazine article.
• A student gets his or her Lexile reader
measure from a reading test or program.
Lexile Levels
• A book, article or piece of text gets a Lexile text
measure when it's analyzed by MetaMetrics. For
example, the first "Harry Potter" book is an 880
Lexile book.
• A Lexile text measure is based on two strong
predictors of how difficult a text is to
comprehend:
– word frequency and sentence length.
– Many other factors affect the relationship between a
reader and a book, including its content, the age and
interests of the reader, and the design of the actual
book.
Lexile Levels
• Lexile levels measure a student’s reading
ability and a text’s difficulty.
• When you receive a Lexile measure, try not to
focus on the exact number. Instead, consider a
reading range around the number. A person's
Lexile range, or reading comprehension
"sweet spot," is from 100L below to 50L above
his or her reported Lexile measure.
Correlations Between Lexile and Grade Levels
Lexile Range
Look at your MAP
Data and
Determine your
grade level reading
based on your lexile
range. Write your
grade level next to
your lexile range.

RIT Scores
• Your RIT score indicates your instructional
level based on the level of questions you
answered correctly 50% of the time.
• A RIT scale is an equal interval scale. This
means it’s consistent, like a ruler.
– A student who shows instructional growth from
160 to 165 shows the same amount of
instructional growth as a student who goes from
285 to 290: five points of growth.
RIT Scores
• RIT scores are independent of grade level,
however there are “typical” RIT scores for
each grade level.
• If a 3rd grade student and an 8th grade student
earn a 210 RIT score this means they are at
the same instructional level.

Percentile Scores
• Percentile score provide the most direct
reference to how a student preformed
compared to the general population of
students in the same age range.
Percentile Scores
• A perfectly average score is 50%.
• The average range is roughly from
25% to 75%.
• Scores at or above the 25th percentile
are probably not of any significant
concern.
• Scores between the 10th and 25th
percentile are of moderate concern.
• Scores below the 10th percentile
suggest relatively significant
difficulty.
