Overview. The Study of
State and Local Implementation and Impact of the Individuals with
Disabilities Education Act, SLIIDEA, has been designed as a
national assessment to examine how the changes in the 1997 IDEA
amendments are affecting states, districts, and schools, as well
as infants, toddlers, children and youth with disabilities and
their families. The Wave 3 Data Tables represent the responses
from states collected during the 2003-2004
School Year. The census of states included all 50 states plus D.C.
The state survey instrument is available on our
Data Collection Instruments
page. The "source note" at the bottom of each table
indicates the survey item(s).
The discussion of the findings from these tables will appear in
an upcoming report that will be provided on our
Reports page.

3 State data tables:
Technical Note. Except for
conditional findings, each survey item adds to 100 percent. When
conditional questions were asked on the survey, we report these
findings as conditional of those states that
indicated "yes" as the response to the survey item. The
denominator for the conditional items was the number of states that reported "yes," and not of all
states that responded to a particular item.
Here is an example of how a conditional response has been
reported, using a Wave 2 state table: Thirty-nine percent of states reported that they
rewarded districts or schools on the basis of student performance.
Of these states, 11 percent considered the performance of students
with IEPs when making this determination. (See
Wave 2 State
Exhibit 1.9.) In this example, 39 percent represents the
number of states that reported yes, they reward districts or
schools for student performance, divided by the number of states
that responded to the question on rewards. Eleven percent
represents a subset of the 39 percent of states, and is thus, a
conditional percentage of 39 percent. On the other hand, if one
wanted to know the unconditional percentage - that is, how many
states considered the performance of students with IEPs when
determining a reward to districts and schools - one would multiple
11 percent by 39 percent by 100 to equal 4 percent (.11 x .39 = .04
x 100 = 4 percent).
And finally, in each exhibit, we present the "Missing
N" and "Total N." We used the following criteria
for determining each of these numbers:
- Missing N: The number of states that had a missing or invalid response for the survey
item.
- Total N: The number of states
providing a valid response to the item.
