<p>What's the difference between STS and ISEF? Does one lead to the other or are they two separate competitions?</p>
<p>I’m pretty sure they’re two different competitions, but I’m not sure what the difference is. I would like to know too</p>
<p>Just check out their website here: [Society</a> for Science & the Public - Intel STS - Home Page](<a href=“http://www.societyforscience.org/STS]Society”>Regeneron Science Talent Search- Society for Science)</p>
<p>Different competitions. STS you apply for and ISEF you have to “qualify” for by winning other science fairs.</p>
