<p>Schools have 12 years to teach at least arithmetic and algebra. That is a very, very long time. If the schools aren’t doing their jobs, then parents have to step in to fill the void. The problem is that parents often don’t know that there is a problem.</p>
<p>I recall the survey results in grad school on how to improve courses. The biggest complaint was on students that didn’t have the prerequisites for the course eating up valuable course time. How can a college professor teach the required material if a lot of course time is spent doing prerequisites?</p>
<p>In this case, the placement tests are fair to everyone. The professor can teach the course. Students in the course aren’t held back by students that won’t succeed in the course. Students that have to take remedial courses will be prepared for the course after they can demonstrate that they can meet the prerequisites.</p>
