Three Primary Uses of
CogAT Scores
• Help teachers adapt instructional goals,
methods and materials to the individual
needs of students
• Measure of each student’s level of
cognitive development
• Identify student whose level of academic
achievement differs from what would be
expected on their CogAT scores
What is the Iowa
Assessment?
The Iowa Assessment is a norm-
referenced test developed by the University
of Iowa.
It tests mastery of the academic skills found
in the elementary curriculum.
The purpose of these tests is to provide
information about student progress in a
curriculum that expands in breadth and
depth with each additional grade level.

What types of Scores for
the Iowa Assessment Appear on a
Student Report?
• National Percentile Rank (NPR)
• Grade Equivalent (GE)

Grade Equivalent (GE)
• Grade equivalents are reported in decimal
format. The number in front of the decimal
is the grade level and the number after the
decimal represents months. (e.g. 3.4
represents third grade, fourth month)
• GE does not indicate a student’s
instructional level.
• GE allows for comparison of growth over
time.
GE Growth Comparisons Low Performing student –
less than 20 months gain in two years
Fall grade 5th grade – 4.2
Fall grade 7th grade – 5.6
Average Performing student –
about a 20 month gain in two years
Fall grade 5th grade – 5.2
Fall grade 7th grade – 7.2
High Performing student –
more than 20 month gain in two years
Fall grade 5th grade – 6.2
Fall grade 7th grade – 8.8

Coming Next – The Georgia Milestones!
Grades 3 – 5
Features the Georgia Milestone Assessment System include:
• open-ended (constructed-response) items in language arts
and mathematics (all grades and courses);
• a writing component (in response to passages read by
students) at every grade level and course within the
language arts assessment;
• norm-referenced items in all content areas and courses, to
complement the criterion-referenced information and to
provide a national comparison; and
• transition to online administration over time, with online
administration considered the primary mode of
administration and paper-pencil as back-up until the
transition is complete.
