I’m sure I’m not alone in feeling that this can be the most intimidating step. The typical score report seems to have more columns of numbers than a tax schedule! On top of the overwhelming amount of information is the feeling that these numbers represent your success or failure as a homeschool teacher. They do not! The test numbers also do not represent your child’s success or failure. Achievement test scores are not pass/fail! They are a snapshot of your child’s work performance and will give you information about his strengths and pinpoint areas you may want to focus on more. The scores do not indicate if your child has passed a particular grade, and they are not a numeric prediction of future success. Achievement tests were originally developed to track how well a program of instruction was working by comparing students with the average student in their grade (in the typical curriculum). They are useful to us as homeschool parents to track how much our child improves from year to year and how they compare to the national average in terms of achievement on the test in question. While there are a lot of statistical values derived from these test scores, the most important for our consideration are grade equivalency (GE) and percentile rank. (PR). The number of questions a student answers are converted into these two values for interpretation of the student’s performance relative to the group or grade in question. To understand these you must first understand how these values are distributed across a normal curve. Test material is composed of tasks and questions which are typical for the designated grade in terms of difficulty and scope. In theory, a third grade test will be composed of questions and concepts that are typical for third grade across the nation. The difficulty range for this material is probably between the second grade and fourth grade to account for the variations between curriculum and student achievement; notice grade three is right in the middle. Thousands of students (the reference group) are given the test and their scores are used to develop the normal curve for this particular instrument. The statistics for this are not complicated, but are more detailed than can be explained here. To simplify: by definition a normal curve shows a distribution of scores where most students fall in the middle range, i.e. average. The mean (average) score is the exact middle of the range of all scores and the number of students achieving that score are represented by the height of the curve. In the chart below, notice that 68% of the students are average because they fall under that part of the curve. The percentile rank (PR) range is from 1 to 99, with the middle 50 percentile located at the mean test score of the group. The percentile rank indicates how each score relates to the total reference group. A PR of 75 means that 75 percent of the students in the reference group scored lower than your student or that your student scored in the top 25 percent of all students. Remember, percentiles do not tell you how much of the material your student answered correctly; a PR score of 80 does not mean they got 80 percent of the material correct. Percentiles are useful for three things: Percentiles tell you where your student stands compared to others in that grade. A student scoring in the 75 percentile on most achievement tests is at the top of the average range, a student in the 25 percentile is near the lower range for the average student. This is why it is a concern if a student scores below the 25 percentile. Percentiles also indicate relative performance between subject areas for a particular student. A student may score 80 percentile in reading and 20 percentile in math and still be average overall. These scores would indicate a weakness in math compared to reading. This could indicate a general weakness in ability or it could mean that more attention needs to be paid to math instruction. Percentiles may also tell you if a child is falling behind. A student who scores 25 percentile one year in reading and 15 percentile the next year is falling behind in this skill compared to others in his grade.   Grade equivalency (GE) is the other important score for homeschoolers and also the score most commonly misunderstood. The number of correct answers on a test section is converted to the GE scores for the simple reason that grade level serves as a reference point that most people can understand in terms of the real world of educational material. GE scores are represented by a number like 3.5, where the number to the left of the decimal is the grade and the number on the right is the month of instruction in that grade, in this case a third grader in the fifth month of a nine month school year. Confusion occurs when these numbers are taken too literally. The third grader who scores GE 6.7 on reading is reading quite well for a third grader, but they are not necessarily reading sixth grade material. They certainly can’t be skipped ahead to the sixth grade in terms of curriculum. The reason you can’t assume the child is ready for sixth grade is that a third grade test would contain only material with a difficulty level slightly above and slightly below third grade. A more accurate way to understand the score is to say that this student is reading as well as a sixth grader would read third grade material. The student would probably not be successful with sixth grade material, but they should be able to read third grade material with relative ease. Therefore, be careful when using GE scores […]
