STUDENT ACHIEVEMENT DATA
FOR 2004-2005
School districts must report to the
Iowa Department of Education the percentage of their students in fourth, eighth
and eleventh grades who are proficient in reading, math and science. For the
2004-2005 school year,

The Iowa Department of Education
requires districts to report student proficiency levels on “one valid and
reliable district-wide assessment.” The basic definition for proficient is when
a student scores at the 41st percentile or above on the
district-wide assessment. Most public and private
Obviously, many different things
affect student achievement. Research has shown that high quality teachers who
administer high quality instruction is probably the single most important
factor linked to student achievement. Effective teachers who instill the desire
to learn, help students develop a positive self-image, are enthusiastic
themselves about what they are teaching and welcome parents as partners in the
education of the child usually generate very positive results.
Additionally, the Iowa Department of
Education requires schools to report a standard error of measurement, which is
as follows:
A
standard error of measurement (SEM) is an estimate of possible error associated
with an individual student’s test score. The SEM can be described as a band of error. A test score is an estimate of a student’s true test
performance; however, when the SEM is applied, it indicates that a reasonable
chance exists that the student’s true score may be slightly higher or slightly
lower than what is reported. For the Iowa Test of Basic Skills (ITBS) and Iowa
Test of Educational Development (ITED), the SEM’s are
presented in ranges, indicating where the student’s true score would likely
fall (see table below).
