ERB TESTING REPORT - Cary Academy

ERB TESTING REPORTMiddle School, May 2011In May 2011, students in grades six through eight took the Educational RecordsBureau’s CTP 4 standardized test (ERB’s). The CTP 4 is a battery of testsdesigned to provide information about student performance in key areas of theschool curriculum: reading, vocabulary, writing and mathematics. The tests alsocontain reasoning assessments in language arts and mathematics. Theachievement and reasoning sections are intended to provide comparisonsbetween what the student is learning at a particular point in school (achievementtests) and how well the student can call upon higher-level thinking skills to solveproblems (the reasoning tests). An explanation of the test areas follows at theend of the report.The following charts provide a summary of the results from those tests. Theinformation is taken from data in the Administrator’s Summary, and displays ourstudents’ performance by grade, test area, and percentile rank.The results compare the performance of our students at the 25 th, 50 th and 75 thpercentiles 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 theverbal reasoning test, our sixth grade students at the 50 th percentile are at the93 rd percentile when compared with the national population, and at the 68 thpercentile when compared with an independent school population. This meansthat a Cary Academy student in the middle of last year’s sixth grade class earneda score in verbal reasoning that was equal to or higher than scores earned by 93percent of sixth grade students nationally. The scores of this student are alsoequal to or higher than 68 percent of his or her independent school peers.In reviewing all test areas and grade levels at the 25 th percentile, 50 th percentileand 75 th percentile, we can conclude that our students, grades 6-8, performedsignificantly higher on all test areas than the national population. We can alsoconclude that the performance of our students, grades 6-8, is equal to or higherthan that of the independent school population on all test areas.Please feel free to contact Marti Jenkins at 228-4570 should you have questionsabout the report.1

A percentile rank indicates a student’s relative standing in a norming sample, it doesnot indicate the score itself. The 50 th percentile corresponds to the median, and indicates that astudent scored higher than half of the sample and lower than the other half.2
