How do you submit teacher recommendations?

<p>So I looked on the Washington University in St. Louis website, and they have special teacher recommendation forms. In addition, they say that (quote) "Teacher recommendations may not be submitted online."</p>

<p>Further, Harvard College also says something to the same effect.</p>

<p>The Common App, however, still has a school forms option for these schools and allow them to be submitted that way! So now I'm really confused: how does one submit teacher recommendations?! Does each college do it a different way?</p>

<p>For those colleges which accept common app, invite the teachers from the website. They will submit once. Whenever we apply in a new college, invite the teacher for that particular college. The rec will be automatically submitted. Even though Wash-StL. accepts the common app, for scholarships, we need to print the form, give to teachers. They will send it confidentially to the college.</p>
