Is the texas top 10% law only for public high schools?

<p>So I always thought it was the top 10% for any high school, not just public but someone told me it was only for public, is this true? And I know that the percentage is lower at UT austin, but does this only apply to public school?</p>

<p>Potentially, private high schools qualify but some don’t rank for some reason.</p>
