I have been fortunate enough over my twenty years in education to teach at virtually every grade level, from primary to high school, and in almost every "
socio-economic"
environment, from the very disadvantaged to the extremely fortunate. Each of these varying demographics has had their own challenges and rewards, but what has always been the most striking thing to me is the
similarities they all share.
One of these similarities, which I have said many times, and I may have written it here, is that Catholic schools do a great job of educating our students, ass well as graduating
good people. I have been able to state this about the children at every school I have worked in, no matter what the climate in their surrounding community.
In addition to graduating good people, another
hypothesis I have formulated during my teaching is that I really don't think individuals are born significantly smarter than one another. Working in primary grades, I often saw a good majority of children who were on relatively equal footing at the start of their school experience. They were not significantly higher or lower than their classmates, in terms of reading or math. Years later, teaching these same children in junior high, it was very apparent that somewhere along the way a gap began to develop regarding their education. Some of those children were now significantly ahead of the same students they were on the same level with in second grade, and vice-
versa.
The reason this has been on my mind lately is due to the recent sharing of our
standardized tests scores with our parents. Our children do well, and we see that by the time they are in eighth grade they are, generally, achieving well beyond their grade level, according to these tests scores. Most of our students in each grade are testing at similar levels, and thus our school scores are "high".
This seems concerning to the parents who compare them with our second grade scores, and see their children are "only at grade level. I have had numerous parents ask, "What's going on with them?" and I tell them they have accidentally stumbled upon one of the flaws of standardized testing, and
particularly, the reading of class or school percentiles.
Because a parent asked
specifically about science scores in the second grade, i opted to use these scores as an example to answer the many questions. The second grade class average was in the 51st percentile rank for
science. The 50
th per
centile represents grade level, but it is significantly below what our students score in other grades, and it seems to be a cause for alarm that our kids are "only" on grade level in certain academic realms (according to these test scores). So I
disaggregated the information and this is what I found.
The science
subtest for the second grade had 31 questions covering four ares of science.
7 questions were on
Scientific Inquiry. 85% of the class got the answers correct.
14 questions were on Life Science. 81% of the class answered the questions correctly.
4 Questions were on Earth and Space Science. 77% of the questions were answered correctly.
6 questions were on Physical Science, with 81% of the class answering correctly.
What this tells us is that our students answered the questions with a relatively high success rate. But so did all the other students across the nation who took the test. Thus, it is the "average" for the grade level and comes across as grade level. Most of the second grade students across the country are on the same level as our students in science. So, despite a class that answered most of the questions correctly, the class average appears to be low or bad. Another way to look at it is if the entire nation got all the questions incorrect on the science test, and Holy Angels students got 10% of the questions correct, we would be in the 99
th percentile, even though it does not mean we knew the material well. Obviously, this is an extreme example, but it illustrates my point.
Interpretation of test scores is a very tricky thing to do, and misinterpretation is an extremely easy mistake to make. The only scores that truly matter, in terms of standardized testing, is your own individual child's. As one can see, failure to have ALL of the information can lead to a miscalculation of what the numbers mean. Standardized tests are just one piece of a very complex puzzle that add up to academic success for a child, and this must never be forgotten. So, don't get to hung up on our school's perceived success or failure on a test. Stay involved in what your child is doing in the class and how they are achieving there.
