Using STAR Early Literacy
Enterprise™ Scores to Match Books
to Early Readers
Renaissance Learning, Inc. offers two computer-adaptive assessments of reading skills: STAR Early
Literacy Enterprise and STAR Reading™.

STAR Early Literacy Enterprise, a criterion-referenced assessment for students in grades
pre-Kindergarten to 3, measures students’ skills in ten content areas essential to reading
readiness. Primary-grade teachers can use the data provided by STAR Early Literacy Enterprise to
monitor students’ reading development and guide planning and instruction.

STAR Reading, a norm-referenced assessment for students in grades 1–12, measures students’
reading comprehension. It provides Grade Equivalent (GE) scores as one measure of reading
achievement. GEs indicate the normal grade placement of students for whom a particular Scaled
Score is typical. For example, a student with a GE score of 1.3 has performed as well on STAR
Reading as a typical first-grade student in the third month of school. For each student assessed,
STAR Reading also provides a Zone of Proximal Development (ZPD) to help teachers match
appropriate books to students. A student’s ZPD represents the range of book readability levels
that is neither too hard nor too easy, and is the level at which optimal learning takes place.
To help teachers match books to early readers, Table 1 (on the next page) displays correspondences
between STAR Early Literacy Scaled Scores and literacy development classifications on the one
hand, and STAR Reading Scaled Scores, GE scores, and ZPD ranges on the other.
This table was developed by linking (equating) STAR Early Literacy and STAR Reading Rasch ability
scores, then converting the linkage results to Scaled Scores of the two assessments.
The linking analysis began by identifying students who took the Enterprise versions of both STAR
Early Literacy and STAR Reading concurrently during the 2012–2013 school year. More than 300,000
students who had taken both tests within 15 days of one another formed the concurrent tests data
set. The linkage work employed linear equating analyses of a random sample of 25,000 matched
pairs of scores from that data set. STAR Early Literacy Enterprise and STAR Reading measure related
constructs, and were highly correlated (r = 0.71) in the concurrent data set.
STAR Reading GE scores in Table 1 are based on 2014 norming data for the Enterprise version of the
test, and therefore the Scaled Score ranges corresponding to the GE scores have changed
somewhat compared to earlier published versions of the table. STAR Reading ZPD ranges are
determined by the GE scores; the correspondence between GE scores and ZPD ranges is unrelated
to the new norms, and has not changed.
The primary purpose of Table 1 is to provide a link between STAR Early Literacy Scaled Scores and
STAR Reading GE scores, and thus to ZPD ranges, in order to facilitate matching readers to books in
Accelerated Reader. It can also be used to identify STAR Early Literacy and STAR Reading Scaled
Scores that are approximately equivalent. However, those tests are not the same test, and do
measure somewhat different aspects of reading development. Therefore, Table 1 is meant only as a
general guide. It should not be used to make decisions about students’ early reading achievement
or to calculate actual GE scores.

In addition to providing approximate GE scores and ZPDs, this table helps determine whether a
student previously tested with STAR Early Literacy Enterprise could complete a STAR Reading test.
The 2001 STAR Early Literacy Validation Study data indicate that a student with a STAR Early
Literacy Enterprise Scaled Score of 682 or higher is likely able to complete a STAR Reading test
without getting frustrated. However, teachers should consider both the Scaled Score and their
knowledge of the student’s reading proficiency when selecting a reading assessment. Moreover,
although a student may be capable of taking a STAR Reading assessment, teachers may want to
continue using STAR Early Literacy Enterprise with the student to diagnose strengths and
weaknesses in literacy skills and to plan reading instruction.
