This report focuses on the participation and performance of students with disabilities on the initial administration of Minnesotas Comprehensive Assessments (MCAs). Assessments in Mathematics and Reading were initially administered to students in third and fifth grade in 1998 and 1999. The test of Written Composition was administered to fifth graders only. Data used in this report were compiled through the Minnesota Assessment Project, a four-year, federally funded project from the Office of Educational Research and Improvement to the Minnesota Department of Children, Families and Learning, in collaboration with the National Center on Educational Outcomes (NCEO) at the University of Minnesota. The Minnesota Assessment Project has published many reports on the participation and performance of students with disabilities and English language learners in statewide assessments. These reports are available on-line at http://education.umn.edu/NCEO.
The participation
and performance of students with disabilities within a statewide assessment process are
important to study, especially in light of the 1997 reauthorization of the federal
Individuals with Disabilities Education Act (IDEA). This act sets the expectation that all
students with disabilities will participate in statewide assessments, with accommodations
as needed, or through participation in alternate assessments. In addition, states must
report the number of students participating in the regular assessment and the performance
of those students. This must be done in the same way and with the same frequency as the
performance of students not receiving special education services is reported. The
reauthorized IDEA has placed greater emphasis on the access of students with disabilities
to the general education curriculum and their participation in it, and on district and
state assessments that drive the curriculum. In Minnesota, as in most states, IDEA sets
the stage for the initiation of increased participation. (See Appendix A for Assessment
Provisions of IDEA.)
Title I of the
Improving Americas Schools Act of 1994 (IASA) requires all states to develop high
standards for the academic achievement of all students, particularly those who are low
achieving. Furthermore, the law specifies that educational accountability is to be
improved through the use of state assessment systems designed to show how well students
are achieving the challenging state student performance standards expected of all
students. According to the National Research Council (1999), standards provide a way to
focus support for schools that have difficulty educating all students to the same high
level. The National Research Council calls upon states to monitor the implementation of
standards and to make changes where needed. Students who seem to have particular
difficulty achieving high standards are students with disabilities.
Historically, many
students with disabilities have been excluded from assessment and accountability systems
across the United States. Although assessments have been the primary means to evaluate
educational accountability, students with disabilities have been excluded to a great
extent (Erickson, Thurlow, & Thor, 1995; Thurlow, Elliott, & Ysseldyke, 1998).
Increasingly, states are making significant efforts to include all students and to report
the performance of students with disabilities on statewide tests (see Thurlow, Langenfeld,
Nelson, Shin & Coleman, 1998). Many states are just beginning to have the capacity to
disaggregate statewide assessment data by disability, but most are still not able to
calculate the percentages of students with disabilities actually participating in the
assessments (Thompson & Thurlow, 1999).
Minnesota Comprehensive Assessments
Minnesota has
developed a system of high standards that are being implemented at all grade levels.
Students must complete standards in specific areas during their high school years to earn
a high school diploma. In order to determine whether elementary and middle school students
are learning the concepts and skills needed to complete the high school standards when
they are older, the Minnesota Department of Children, Families and Learning (CFL) has
created preparatory standards for students in kindergarten through grade eight. To assess
progress toward the preparatory standards, CFL has developed and implemented statewide
assessments in Reading and Mathematics in third and fifth grades, with a test of Written
Composition added in fifth grade. In addition to testing third and fifth graders, the
Basic Standards Tests, administered as a graduation requirement beginning in eighth grade,
are also used as a measure of accountability. Comprehensive assessments are currently
being developed for eleventh graders.
The Minnesota
Comprehensive Assessments (MCAs) are criterion-referenced tests used for district
accountability purposes, and as tools for making decisions about curriculum and
instruction. The tests were first administered in February of the 1997-98 school year, and
are to be administered on an annual basis. The MCAs represent one component of Minnesotas
educational accountability system. The tests are designed to monitor the educational
system in Minnesota and in each district. Although individual student scores can be
reported from the MCAs, the tests are designed for system accountability rather than
individual student or teacher accountability. There is no passing score that all students
are expected to achieve; rather, performance is reported at four proficiency levels.
State, district, and school test results are used in several ways:
to measure the success of schools and districts in improving
student achievement over time;
to generate information for school improvement and
accountability;
to allow for identification of programming and strategies that
work; and
to allow for comparison of schools and districts in Minnesota.
The MCAs were
designed by a team of more than 200 Minnesota educators in addition to national experts in
Reading and Mathematics. The Reading and Mathematics tests have multiple choice and short
answer items. There are 10 forms of the test with 49 common items (58 possible points) and
11 additional items, called matrix items, that vary across test booklets (14
possible points). Individual student results are reported only on the common items found
in every students test booklet. School or district results include both the common
items and the matrix items. Tests are untimed, with one test given each day.
At grade 3, the
Mathematics test includes questions about shape, space, and measurement; number sense; and
chance and data handling. For example, to assess the number sense standard, the test may
ask students questions about counting whole numbers and identifying odd and even numbers.
The Reading test covers informational material (e.g., from textbooks), practical
information (e.g., recipes), and literature. On average, test items are written at a third
grade reading level.
At grade 5, the
Mathematics test includes items in the same areas as those assessed in grade 3: shape,
space, and measurement; number sense; and chance and data handling. However, the types of
problems are different. For example, to assess the number sense standard at grade 5,
students may be asked questions about place value, number operations, estimating, and
calculator use. The Reading test covers material in the same categories as those on the
third grade test (informational material, practical information, and literature), with the
average passage written at a fifth grade level.
The test of Written
Composition was only administered in fifth grade. Students were expected to write a short
essay based on one of four types of story prompts: narrative, problem/solution,
descriptive, and clarification. Each essay was rated on a four-point scale across the
domains of composing, style, sentence formation, usage/grammar, and mechanics/spelling.
Each of the story prompts was administered to a proportion of fifth graders.
MCA scores are
reported within four proficiency levels. Raw scores are converted to scale scores and
categorized within Levels I IV, as shown in Table 1 (similar to the National
Assessment of Educational Progress performance levels). Students reaching Levels III and
IV have demonstrated the capacity to successfully achieve Minnesotas high standards
and are on track to achieving Minnesotas Graduation Standards. A desired goal is to
have all students performing at or above Level II. Although it is assumed that all
students will benefit from the focused approach that the Graduation Standards offer, it is
likely that students who score at Levels II and I are most dependent on focused,
performance-based instruction. Parents and teachers of these students should weigh the
assessment results against other evidence of achievement.
Table 1. MCA Performance Levels
Level IV: Students at this level demonstrate evidence of advanced academic performance, knowledge, and skills that exceed the level necessary for satisfactory work in the high standards in the elementary grades. |
Level III: Students at this level demonstrate evidence of solid academic performance and competence in the knowledge and skills necessary for satisfactory work in the high standards in the elementary grades. |
Level II: Students at this level demonstrate evidence of partial knowledge and skills necessary for satisfactory work in the high standards in the elementary grades. |
Level I: Students at this level demonstrate evidence of limited knowledge and skills necessary for satisfactory work in the high standards in the elementary grades. |
Students with
Individualized Education Programs (IEPs) or 504 Accommodation Plans (504 Plans) are
expected to participate in the MCAs as generally administered or with approved
accommodations (see Minnesotas Accommodation Guidelines in Appendix B). Because data
from these tests are used for system accountability, modifications to the test are not
allowed. Results of these tests do not influence a students graduation or promotion
status. Students with IEPs or 504 Plans who are unable to participate meaningfully in the
MCAs will be included in the accountability system through participation in an alternate
assessment designed by CFL. The alternate assessment includes various rating scales for
developmental academics or functional skills and was required to be in place by July 1,
2000 (see Appendix A, Assessment Provisions of IDEA).
The CFL collected
the data analyzed for this report through the Minnesota Automated Recording Student System
(MARSS), Minnesotas data management system. Statistical analyses were run by
Minnesota Assessment Project (MAP) researchers. The analyses were translated into tables,
discussed by the MAP team, and this report was written. Before publication, special
education and assessment consultants at the Minnesota Department of Children, Families and
Learning reviewed this report.
There are several
cautions to consider in the interpretation of these data. The cautions fall into four
areas: reporting by grade, reporting by primary disability, reporting only students with
disabilities who receive special education services, and other considerations.
Reporting by grade. The data included in this
report are presented by student grade and disability. Student grade is defined as the
grade a student is in during the testing year. The participation rate is calculated by
dividing the number of students tested in a particular grade by the total number of
students enrolled in that grade.
The official special
education child count that is reported to the federal government is calculated on December
1 and reported by age. These numbers cannot be used to calculate test participation rates
because tests are administered by grade, not by age. Pupil enrollment information is
calculated by grade on October 1 of the testing year. This raises some concerns, since
there are about five months between the child count date and the test administration date,
during which time some students move in and out of districts, and in and out of the state.
Reporting by primary disability. Students are
reported only by their primary disability, even though many of them have additional
disabilities (e.g., students with a speech impairment and a learning disability may only
be reported as having a learning disability). Using only primary disabilities reduces
child count error by ensuring that no student is reported more than once. Unduplicated
child count data are essential for calculating participation rates these data
become the denominator. However, the fact that a student may have more than one disability
increases the number of factors that may contribute to student performance. We cannot draw
inferences about the data in these more complex ways because we do not have the
information needed to do so.
Reporting only students with disabilities who receive
special education services. Throughout this report, we refer to the group under
consideration as students with disabilities. However, the students counted in
the report for 1998 include only those receiving special education services during the
testing year. We were able to include additional information about students with 504
Accommodation Plans in 1999. Students with disabilities who do not qualify or choose not
to receive special education services have not been identified.
Additional reporting considerations. There are
three additional reporting considerations to take into account. The first is that data
from a small number of students are not included because the data were inaccurate or
incomplete. Second, there are some students who are included in the child count who did
not take the MCAs because they received their education in private or home-schools. Third,
students in some special education categories are not included in these analyses because
the group is too small in number to maintain the anonymity of individual students.
As you view the
figures and tables throughout this report, keep in mind that the numbers and percentages
represent a broad number of factors. Only if all things were equal could we look at a
change in percentage and say it truly represented a change in test participation or
performance. Still these data are the first to portray the participation and performance
of students with disabilities on Minnesotas Comprehensive Assessments.
Results
Participation
School districts
across Minnesota included nearly 85% of third and fifth graders with IEPs or 504 Plans in
the 1998 and 1999 MCAs. Minnesotas 1998 and 1999 participation rates on statewide
assessments for students with disabilities are among the highest in the United States
(Thompson & Thurlow, 1999). The number and percent of students participating in the
third and fifth grade MCAs are reported here for 1998 and 1999, by grade and by test.
As shown in Figures 1 and 2, participation rates were fairly consistent across grades, tests, and years, with an overall participation rate of about 95% for all students tested. Students with disabilities participated at an average rate of 84%. Table 2 presents these data both by number and percent. Based on these data, it is assumed that roughly 16% of students with IEPs or 504 Plans were either exempt from testing, absent on at least one testing day, or were not tested for a variety of other reasons.

Participation rates
by disability are shown in Table 3. Enrollment remained stable across grades 3 and 5 for
students representing most disability categories. The exceptions are in the categories of
learning disability and emotional/behavioral disorders. The number of students receiving
special education services in these categories increased by about 50% from third to fifth
grade.

Participation rates
of students across disability categories were similar in 1998 and 1999. Students with 504
Accommodation Plans participated at a rate even higher than students without disabilities.
Students with learning disabilities (87% - 91%) and students with speech/language
impairments (84% - 92%) also participated at very high rates, as did students with
emotional/behavioral disorders (83% - 89%). Participation of students with moderate to
severe mental impairments was the lowest (4% - 9%). Participation rates of students with
deaf/blindness are not reported in order to protect the identity of individual students (N
< 10). Figures 3 through 7 compare participation rates by disability across years,
grades, and tests.

MCA raw scores were
converted to scale scores using NAEP (National Assessment of Educational Progress)
performance guidelines. The expected mean was approximately 1400 with a standard deviation
(SD) of about 200 for all students tested. Scale scores are important to study for an
overall picture of average performance, but it is also important to examine the MCAs in
the context through which performance is most commonly viewed; that is through proficiency
levels. MCA scale scores are divided into four performance levels that vary from grade to
grade and test to test, as shown in Table 4. The following section summarizes the
performance of third and fifth graders using both scale scores and proficiency levels.

Third Grade Performance
Scale Scores. Figures 8 and 9 show the mean scale
scores for third graders in Mathematics and Reading across both testing years. On average,
1999 third graders scored higher than third graders in 1998, with a greater increase in
Mathematics than in Reading. The performance of students across all disability categories
averaged about .5 to 1 standard deviation (100 to 200 scale score points) below the
expected mean. Students receiving speech and language services nearly met the expected
mean, while students with mild to moderate and moderate to severe mental impairments
averaged 1.5 to 2.5 standard deviations below the expected mean. Note that the number of
students with moderate to severe mental impairments tested was very low (<15), limiting
interpretation of the results.

Figure 9. Performance: Mean Scale Scores
3rd Grade Reading by DisabilityProficiency Levels. As expected, between 70% and
80% of all third graders tested scored within Levels II or III on both tests, both years
(Table 5). The percent of all students, including students with disabilities, scoring at
Level IV increased from 1998 to 1999. In 1998, 45% of students with disabilities scored at
Level I in Mathematics and 59% scored at Level I in Reading. By 1999, the percent of
students with disabilities scoring at the lowest level dropped by 10% in Mathematics and
4% in Reading.

Figures 10 and 11
show the proficiency levels of third graders by disability in 1999. Students receiving
speech and language services were the highest performing group of students with
disabilities on both tests. Figure 10 shows that about 30% of students with speech
impairments, emotional/behavioral disorders, deaf/hard of hearing, and visual impairments
scored within the lowest proficiency level in Mathematics. Forty to fifty percent of
students with autism, learning disabilities, other health impairments, physical
disabilities, and traumatic brain injuries scored at Level I in Mathematics, with 90% to
100% of students with mild to moderate and moderate to severe mental impairments scoring
at this level. Except for these last two groups, about the same percent of students across
disability categories scored at Level II, with fewer at Level III, and a very small number
reaching Level IV.

Overall, more
students scored within Level I on the Reading Test than on the Math test. Over 40% of
third graders with all disabilities except speech impairments scored at Level I in
Reading. The percent of students reaching Level II was lower than the percent at Level I. Fewer than 20% of students across most disability
categories scored above Level II in Reading. No students with mild to moderate or moderate
to severe disabilities scored above Level II. Even though many of the mean scale scores
improved from 1998 to 1999, few of the increases were great enough to increase overall
proficiency levels.
Fifth Grade Performance
Scale Scores. Figures 12 to 14 show the mean scale
scores for fifth graders in Mathematics, Reading, and Written Composition across both
testing years. The average performance of all fifth graders tested set the expected mean
at about 1400. As a group, students with disabilities averaged about .75 SD below the
expected mean.
