California Standards Tests
For each school, district, county, and the state, the following
types of scores are reported by grade level and content area:
 Mean scaled score is the group average scaled score for each
grade and content area. The California Standards Test scaled scores
range from approximately 200 to 500. Scores between 300 and 349
are at the Basic Performance Standard (Academic Achievement Standard)
and scores of 350 or higher are at or above the Proficient Performance
Standard.
 % Advanced, % Proficient, % Basic, % Below Basic and % Far Below
Basic is the percentage of students in the group whose scores
were at this performance standard. The state target is for every
student to score at the Proficient or Advanced Performance Standard.
 Average Number Correct/Number Possible for Integrated Sciencethe
State Board of Education has not adopted performance standards
for the four integrated science tests. These tests each have 60
questions, and the score reported is the average number of questions
the students in the testing group answered correctly.
Stanford 9
For each school, district, county and the state, the following types
of scores are reported by grade level and content area:
 NPR (national percentile rank) for "AVG" Student estimates
the national percentile rank for a hypothetical average student
in this group.
 % Scoring Above 75th NPR is the percent of students in this
group that scored above where 75% of the students in the national
sample scored. If this group looked like the national sample,
this number would be 25. A number greater than 25 indicates that
the group had scores better than the national sample. A number
less than 25 indicates that the group did not do as well as the
national sample.
 % Scoring At or Above 50th NPR is the percent of students in
this group that scored at or above where 50% of the students in
the national sample scored. This is the percentage of students
considered as scoring at or above their grade level on this test.
 % Scoring Above 25th NPR is the percent of students in this
group that scored above where 25% of the students in the national
sample scored. If this group looked like the national sample,
this number would be 75.
Mean scaled score is the group average scaled score for each grade
and content area. A scaled score is a number that the test publisher
uses to calculate other scores. A table is used to convert the number
of questions each student answered correctly to a scaled score.
The scaled scores can then be averaged and used to look up other
scores.
SABE/2
For each school, district, county, and the state, the following
types of scores are reported by grade level and content area:
RPR (reference group percentile rank) of the "average" student
estimates the individual percentile rank of a hypothetical average
student in this group. Reference percentiles are similar to the
national percentiles used for the Stanford 9, but where the Stanford
9 compares student achievement to a sample of students selected
to represent the nation as a whole, the reference group used for
the SABE/2 was selected to represent Spanishspeaking students in
bilingual classes.
 % (Percent of students) scoring above 75th RP is the percent
of students in this group that scored above where 75% of the students
in the reference group scored. If this group looked like the reference
group, this number would be 25. A number greater than 25 indicates
that the group had scores better than the reference group. A number
less than 25 indicates that the group did not do as well as the
reference group.
 % (Percent of students) scoring at or above 50th RP is the percent
of students in this group that scored at or above where 50% of
the students in the reference group scored.
 % (Percent of students) scoring above 25th RP is the percent
of students in this group that scored above where 25% of the students
in the reference group scored. If this group looked like the reference
group, this number would be 75.
 Mean scaled score is the group average scaled score for each
grade and content area. A scaled score is a number that the test
publisher uses to calculate other scores. A table is used to convert
the number of questions each student answered correctly to a scaled
score. The scaled scores can then be averaged and used to look
up other scores.
