Understanding the Different Scores on STAAR
There are multiple scores reported with each STAAR Assessment; it is important that you understand the differences in
each distinct score.
Raw score and percentage score can and often do change with different test administrations. We do not know until after
a test is administered how many questions are required to meet standard on that particular assessment. However the
scale score stays constant whether the STAAR test was given in 2012 or 2015.
Here are some of the STAAR score definitions:
Raw Score
- the number of questions correct
A raw score can be interpreted only in terms of one particular set of test questions.
Percentage Score
– the percent of questions correct based on the number of correct answers out of all the
questions on that particular set of test questions
questions correct
X
100
=
______%
questions tested
A percentage score can only be interpreted in terms of that one particular set of test questions.
Scale Score
- conversion of the raw score onto a scale that is common to all test forms for that assessment
The scale score takes into account the difficulty level of the specific set of questions on which it is based. It quantifies a
student’s performance relative to the passing standards or proficiency levels.
Scale scores allow direct comparisons of student performance between specific sets of test questions from different test
administrations. Scale score can be interpreted across different sets of test questions.
Level II: Satisfactory Scale Score
– met standard scale score
The Texas Education Agency set four phase-in levels with Level II: Satisfactory performance in order to allow
transition with the new STAAR assessment. Those different phase-in scale scores are reflected in the tables
found on page two.
Level III: Advanced Scale Score
– reaching an advanced academic level on that particular assessment
There is no phase-in with Level III; the Level III scale score has stayed the same from its inception in 2012.
STAAR Progress Measure
– a comparison of your child’s score last year with his/her score from the previous
year. This measure gives you information about how much your child improved in the subject from one year to the next.
Texas English Language Learner (ELL) Progress Measure
– a measure on how students are
expected to perform on STAAR tests given their level of English and the amount of time they’ve been going to school in
the United States. It is based on the child’s 2014 STAAR and 2014 TELPAS results.
