Keep LEAP (CRT)
• grades 4 & 8

Keep GEE (CRT)
• grades 10 & 11

Augment The Iowa Tests (NRT + CRT)

Basic Scores Needed for a Test

Raw Score: Number of items correct
• Has little meaning unless you know the
total number of items on a test and how
difficult the test is

Scaled Score: Scores to which raw
scores are converted by statistical
transformations
• Put results from different tests on the same
•
scale
Allows for comparisons

NRT Score: Percentile Rank
Percentile Rank: Percentage of
students in the norm group that the
student scored equal to or above
• The norm group is the group used to
•
establish “typical” or average
performance on a particular test.
Example: A percentile rank score of 70
means that the student scored the same
as or higher than 70% of the students in
the norm group
NRT Score: Stanine Score
Stanine Score (Standard Nine): The
entire range of scores is divided into 9
parts and each is given a number.

Purposes of Using NRT Results

To determine how well individual
students perform relative to the norm
group students who took the same test.

To determine how well groups of
students perform, on average, compare
to the norm group students who took the

Purposes of Using CRT Results

To compare the performance of
individual students to a criterion or
standard of performance.
• A criterion may be a predetermined
•
number of correct responses (e.g., 8 of 10
responses).
Standard of performance can be like LEAP
achievement levels (e.g., Advanced,
Mastery, Basic).
Purposes of Using CRT Results
(continued)

To determine the percentage of
students in a school, district, or state
who obtain the criterion or achieve a
performance standard.
• Example: Grade 4 English (2004), State
Purposes of Using CRT Results
(continued)

To compare the percentages of
students at different schools who attain
the criterion or achieve a performance
standard.
• Example: Grade 4 English (2004), Allen
Parish
Purposes of Using CRT Results
(continued)

To evaluate the extent to which
students are achieving relative to a
particular curriculum.

Difference between CRT and NRT
Not the types of test items
 Not the procedures used to develop
items
 Not the procedures used to construct

 The manner in which test results
may be interpreted

Cautions for
Comparison of CRT and NRT
Scores
Not an apples-to-apples comparison
 NRT score does not represent a
student’s performance on the entire
test.
 A student may have a high score on
CRT but a low score on NRT or vice
versa.
 Two students may have the same CRT
achievement level but different NRT
scores.
