RIT Scale
• Linked to Adult Reading and
Curriculum About 280
Math Concepts
• Achievement Scale
• Equal Interval
Test items
• Grade Level are
calibrated
Independent for difficulty
• Cross Graded along the
RIT scale.
Growth
Measurement
About 150
• Shows Growth Beginning Literacy
Over Time and Numeracy

6. Reading Test Score Display
Daniel E. Caster
Your Reading Score is 210
(Determines Meaning 198-213)
(Understands Text 201-214)
(Analyzes Text 213-225)
(Evaluates and Extends Text 203-216)

7. 2011 NWEA Norms
Provides the mean and median RIT for each
grade level at the beginning, middle and end of
year
Mean RIT = the average RIT score for that grade level
based on all students who took the assessment
nationwide
Median RIT = the middle RIT score for that grade level
based on all students who took the assessment
nationwide

9. What is a Lexile?
A Lexile is a unit that measures the amount of
challenge presented by a passage based on
vocabulary and sentence complexity
A Lexile measure represents a location on the
Lexile scale where a reader can expect a 75%
comprehension rate - difficult enough to be
challenging without undue frustration and to
encourage reading progress.

10. Typical Lexile Ranges for Grade
Grade Lexile Range
1 BR to 300L
2 140L - 500L
3 330L - 700L
4 445L - 810L
5 565L - 910L
6 665L - 1000L
7 735L - 1065L
8 805L - 1100L
9 855L - 1165L
10 905L - 1195L
11 and 12 940L - 1210L
*K5 students are typically at the beginning reader stage and usually score a Lexile of BR.
Reporting Lexiles for K5 students isn't required. It is recommended to report out a Lexile for
a K5 student that is above the typical Lexile for K5 students.

11. Interpret Reading Results
How well do these students understand 7th
grade reading material?
How would you develop a “triage” plan for
these students?

12. Mathematics Test Score Display

(Measurement 191-214)
(Geometry 189-203)
(Statistics and Probability 192-204)
(Algebraic Relationships 194-208)

13. Interpret Math Results
How well can these students do
3rd grade math?
How would you develop a
“triage” plan for these students?
