Norm-Referenced Tests
The Florida Department of Education collected data on the norm-referenced
tests administered by Florida School districts during 1995 and 1997 for
grades 4 and 8. The local districts use a variety of nationally normed
tests which vary somewhat in content. The tests are not interchangeable
and the norms are not exactly equivalent, so comparisons between districts
must be considered with caution. For more information about a test used
in a specific school district, please contact the district testing coordinator
for that district.

Each report contains the following information for the reading and mathematics
subtests:
- The number of students who were administered the test.
- The median national percentile rank (NPR) which reveals how a student's
performance compares to other students in the national norm group. The
NPR values range from 1 to 99. An NPR of 50 means that the student scored
the same as or better than 50% of the students in the nation.
- The percent of students with an NPR from 1-25 and the percent with
an NPR from 76-99. In the national norm group, there will be 25% of
the students in each NPR group.
