By Middle school or high school &amp;quot;problematic students&amp;quot; involves people that not only are noisy and disruptive in class, but people that deal drugs, rob people, steal, join gangs, bring weapons to school. Just calling them problematic is really underselling the situation. And the effects of a student that routinely swears at a teacher and causes fights disrupts a large number of students preventing them from learning things.</text><parent_chain><item><author>seanmcdirmid</author><text>&amp;gt; Charter schools kicking out problematic students isn&amp;#x27;t some loophole, it&amp;#x27;s the main point, and it absolutely can improve the education for those that remain.&lt;p&gt;If you kick out the problematic students, the only students you have left are easy to teach non-problematic students.&lt;p&gt;&amp;gt; and it absolutely can improve the education for those that remain.&lt;p&gt;It isn&amp;#x27;t mysterious: you selected the best students, so your results will be the best.

It&amp;#x27;s also the fact that not having to deal with the terrible kids helps the remaining kids.  Fewer class disruptions.  Less slowing down the class to pretend to let the slowest and least motivated keep up.  Etc.&lt;p&gt;This comes at the cost of concentrating the troublemakers in other places, making them far worse for normal kids stuck there.</text><parent_chain><item><author>seanmcdirmid</author><text>&amp;gt; Charter schools kicking out problematic students isn&amp;#x27;t some loophole, it&amp;#x27;s the main point, and it absolutely can improve the education for those that remain.&lt;p&gt;If you kick out the problematic students, the only students you have left are easy to teach non-problematic students.&lt;p&gt;&amp;gt; and it absolutely can improve the education for those that remain.&lt;p&gt;It isn&amp;#x27;t mysterious: you selected the best students, so your results will be the best.
