Testing (results shown on the Present Levels of Performance page shown below) is often confusing for parents, especially in regards to math. The results are often reported in broad terms, e.g. computation or IQ.
Here is an analogy for the testing (in terms usefulness for determining instruction, performance and achievement). We go to the DMV and have to take an eye test. That test is used to determine if we have the physical ability to drive or what we need to ensure we have the physical ability to drive. If our vision is diminished maybe we need glasses in order to drive.
Passing the vision test does not mean we are ready to drive. It means we have the potential to drive. In order to determine if we can actually drive we take a driver’s test.
Similarly, in order to determine what we can actually do in math we need to take a math test (quiz, checkpoint or some type of curriculum based assessment).
Below is a problem aligned with the Common Core of State Standards for Math. I used it as part of a curriculum based assessment to determine the student’s current ability or present level of performance. She had all types of standardized testing results on record but I needed to know if she could pass the actual driver’s test.
