The aspire tests assess students on subjects they have already studied

Replacing them, the ACT launched Aspire, its brand new entry into the world of core curriculum assessment tests. Aspire is a suite of tests for assessing Common Core performance across English, math, reading, science, and writing, addressing students from 3rd grade through to junior year.

Refute it, showing why it is mistaken—an apparent but not real problem; acknowledge its validity or plausibility, but suggest why on balance it's relatively less important or less likely than what you propose, and thus doesn't overturn it; concede its force and complicate your idea accordingly—restate your thesis in a more exact, qualified, or nuanced way that takes account of the objection, or start a new section in which you consider your topic in light of it. this will work if the counterargument concerns only an aspect of your argument; if it undermines your whole case, you need a new thesis.
