A New Series of Briefs for the Race to
the Top (RTTT) Assessment Consortia
Performance of Special Education
Students:
Implications for Common State
Assessments
The performance of special
education students on state
assessments has been the subject of
much discussion and concern. A
common belief is that all special
education students perform poorly on
state assessments.
There are many misperceptions about
the performance of students with
disabilities. It is important for
the Race-to-the-Top Assessment
Consortia to recognize these
misperceptions and their
implications for common assessments.
This Brief presents information on
the range in performance of special
education students. It also
highlights the changes in the
performance of this subgroup over
time.
Performance Levels and Ranges
Historically, special education
students, on average, have performed
below students without disabilities.
Yet there is diversity in the
percentages of special education
students performing at the
proficient and above levels among
the Consortia states (see Figure 1).
In both the SMARTER Balanced
Assessment Consortium (SBAC) and the
Partnership for Assessment of
Readiness for College and Careers
(PARCC) Consortium, the percentage
of special education students
scoring proficient and above varied
from about 15% to more than 70%
across states.
Across all states within and outside
of the consortia, there are clear
gaps between the performance of
non-special education students and
special education students.
Nevertheless, the extent of the gap
varies by state. Different levels of
performance for special education
students are evident even in states
that have similar percentages of
non-special education students who
are proficient and above (see Figure
2).
The percentage of students who
scored at a proficient or above
level hides the range of performance
levels of special education
students. Students earn scores that
may be near to the proficient cut or
far from it. Figure 3 shows the
ranges in the performance of special
education students in one state,
based on a more fine-grained look at
scores (i.e., deciles; students’
scores are divided into ten groups
of equal frequency. In this Brief,
Decile 1 represents the highest 10%
percent of the scores). Notable is
the fact that special education
students perform at all performance
levels, from the highest to the
lowest. Also notable is that
although the largest proportion of
special education students is in the
lower performance decile, most of
the students in the lowest decile
are students who are not in special
education. Similar distribution
patterns have been previously
highlighted in other analyses
(Marion, Gong, and Simpson (2006)
described the overlap in performance
levels for special education
students and non-special education
students in another state) as
well as in data from other states
(we examined ranges in three other
states as well as the state
represented in Figure 2; all of the
states showed similar overlap in the
range of performance of special
education and non-special education
students).

assessment data for grade 4 state
reading assessments submitted to the
U.S. Department of Education. Rates
of students proficient are based on
the number of students tested. The
state membership in the Consortia
reflected in this figure was
accurate as of December, 2011.

Increasing Performance Over Time
The performance of special education
students is often thought to be
persistently low. Yet state
assessment data, as shown in Figure
4, indicate that the performance of
the special education subgroup is
increasing over time. Increases are
greater for students in elementary
school compared to middle school,
and greater for students in middle
school compared to high school.

Students Over Time

data submitted to the U.S.
Department of Education for grade 4,
8, and high school reading
assessments in 2002-03 and 2006-07.
Note: The change across years was
calculated for each of the states
that had data for 2002-03 and
2006-07 in grades 4, 8, and high
school. The average change was
calculated for those states.
Concluding Thoughts
Wide variation exists across states
within each Consortia in the
percentage of special education
students who are proficient or above
on their state assessments. Although
the Consortia will be developing
their own assessment systems, and in
doing so will set their own
performance criteria, it will be
important for them to know where the
states in their Consortia are coming
from in terms of the performance of
their students. This includes having
awareness of the performance levels
of special education students.
Although many special education
students are low performing, they
are not the only low performing
students and are generally not the
most prevalent low performing
students. It is important not to
forget that there are some very high
performing special education
students. Further, special education
students, on average and in most
states, have shown increased levels
of performance since 2002-03. The
Consortia and states within them
should look at their own data on the
performance of special education
students, address whether changes in
their own content or achievement
standards may have affected change,
and think through their own
transition needs as they move to the
new assessments and the new
performance standards.
