<p>"Not even considering the possible language barriers, why would you think these students are all have degrees and certification as teachers?"</p>
<p>Forgive me for being naive, but don't many of our most prestigious schools consider the same level of education to be sufficient to teach UNDERGRADUATES . After all, aren't we taking about the best and brightest students who are worthy of huge financial aid? If the certification is more important at a K-12 in an iine-city than at a university, just make it part of the curriculum or use what ever the universities use to train their FA or TA. </p>
<p>As far as the language barrier, most people are up in dismissive arms whenever the issue of unintelligible TA is raised.</p>
