discussion 7
Mr. and Mrs. Wilkins, thank you for taking the time to review Wanda's test performances with me. Wanda is a very bright student, and I am proud of her performance on the achievement and aptitude tests. While I can certainly understand your concerns, given the difference in her percentiles, let me assure you there is no need to worry.
Both tests represent Wanda's performance data, but because of each test's nature and purpose, it would be inaccurate to compare the two scores.
Let me start by saying that the data you have received is based on two different criteria, therefore we will look at each one separately. Wanda's achievement test was scored and ranked based on a national norm group. This simply means a group of students was previously tested, and Wanda's score was compared with that data. That said, her 65th percentile score indicates that she performed better than 65 percent of the students in the norm group. This by no means implies Wanda is not studying enough. Percentile ranks are not an indication of how many questions Wanda answered correctly, or what she does or does not know. Instead, the scores indicate how well she did relative to other students who have also taken the test.
Regarding her aptitude test, this test is designed to measure Wanda's potential for academic success in the future. They focus more on her abilities and skills that are considered important for success in school. Additionally, this is a test in which students could not study. And again, like the achievement test scores, these scores are based on the norm group's data scores. So, based on the data we received, Wanda scored higher than 90 percent of the norm group. That said, Wanda is doing a great job.
So, in essence, neither test indicates Wanda's "true" performance; however, they are good indicators that she is on the right track, and with adjustments to the instructional program, Wanda will continue to make progress.
If I were Mr. White, I would explain the differences in each of the tests. All tests will not be the same because there are some that will be straight-forward, while the other ones will include more thinking. Even though Wanda scored in the 65 percentile with the achievement test, informing them that this does not means she did not prepare will be suitable. Many students will have great study habits and have great critical thinking skills, but still not be comfortable with how certain tests are given. It seems as if the parents were upset because of the difference in the scores, but this could also indicate that the student may not be a proficient test taker. Emphasizing on how complex standardized tests can be should also be part of the discussion. Popham (2020) stated that "Standardized tests, because they are intended for widespread use, are developed with far more care (and cost) than is possible in an individual teacher’s classroom. " (p.312) With the variety of questions and the way these type of tests are outlined could be the reason why Wanda had that particular score. Elaborating on these aspects could change their view because it could bring about better understanding. Students who have those percentages believe they could have done better, but stress will build up with pressure if these questions are asked by the parents. I would encourage the student to continue to answer the questions with these type of tests to the best especially if she is performing well academically.
