ERB TESTING REPORT

Middle School, May 2012

In May 2012, students in grades six through eight took the Educational Records

Bureau’s CTP 4 standardized test (ERB’s). The CTP 4 is a battery of tests

designed to provide information about student performance in key areas of the

school curriculum: reading, vocabulary, writing and mathematics. The tests also

contain reasoning assessments in language arts and mathematics. The

achievement and reasoning sections are intended to provide comparisons

between what the student is learning at a particular point in school (achievement

tests) and how well the student can call upon higher-level thinking skills to solve

problems (the reasoning tests). An explanation of the test areas follows at the

end of the report.

The following charts provide a summary of the results from those tests. The

information is taken from data in the Administrator’s Summary, and displays our

students’ performance by grade, test area, and percentile rank.

The results compare the performance of our students at the 25 th, 50 th and 75 th

percentiles to the performance of students at the same grade in independent

(schools similar to Cary Academy) and national school populations (urban,

suburban, rural, affluent, impoverished, large, and small). For example, on the

verbal reasoning test, our sixth grade students at the 50 th percentile are at the

94 th percentile when compared with the national population, and at the 71 st

percentile when compared with an independent school population. This means

that a Cary Academy student in the middle of last year’s sixth grade class earned

a score in verbal reasoning that was equal to or higher than scores earned by 94

percent of sixth grade students nationally. The scores of this student are also

equal to or higher than 71 percent of his or her independent school peers.

In reviewing all test areas and grade levels at the 25 th percentile, 50 th percentile

and 75 th percentile, we can conclude that our students, grades 6-8, performed

significantly higher on all test areas than the national population. We can also

conclude that the performance of our students, grades 6-8, is equal to or higher

than that of the independent school population on all test areas.

*Percentile rank is the percentage of students in the norm sample whose scores fall at or below a

given score. A percentile rank indicates a student’s relative standing in a norming sample, it does

not indicate the score itself. The 50 th percentile corresponds to the median, and indicates that a

student scored higher than half of the sample and lower than the other half.
