Stanines are formed by dividing the students in the norm group into nine subgroups on the basis of their test scores. WHAT IS A STANINE?Ī stanine is another way of comparing your child’s performance with the performance of a norm group. the students in schools using the CTP test tend to be an academically strong group in comparison to all students in the nation. A student's percentile rank will be lower in a stronger norm group and higher in a weaker norm group. The percentile rank is a percentage of students in a norm group.īecause some norm groups perform better than others, your child’s percentile rank will differ from one norm group to another. A student who performed better than 70 percent of the norm group but not as well as the other 30 percent would have a percentile rank of 70 in that norm group.Ī percentile rank does not indicate the percentage of the questions that your child answered correctly. Your child’s percentile rank is the percentage of the norm group who had lower scores than your child (plus half the percentage who had exactly the same score as your child). The national norm group statistics are estimates that show how your student's performance would compare with the scores that would have resulted if all the students in your child's grade had taken the test during their grade year.Ī percentile rank is one way of comparing your child’s performance with the performance of a norm group.
The statistics for the national norm group are estimates based on data from a that administered the CTP 4 tests in a special “national norming” study. The national norm group includes all the students at the appropriate grade level in all schools in the nation- large and small schools rich and poor schools urban, suburban, and rural schools. The independent norm group those independent schools who took that test during the three previous years. The independent norm group consists of students in independent schools that use the CTP tests.
The suburban norm group includes all suburban schools who took that test during the three previous years. The suburban norm group consists of students in suburban public schools that use the CTP tests. The rest of the report contains a table and a graph showing the Student Percent Content Mastery scores that your child earned on each test and on the questions in each content category.Ī norm group is a group of students with whom your child is being compared- usually other students in the same grade. The first page of the report contains a table showing your child’s relative position on each test compared to the National Norm, Independent Norm and Grade. The report contains two kinds of information about your child: The Individual Subscore Report that your child’s school has given to you with this guide describes your son’s or daughter’s performance on the CTP tests.
