Recommendations from former retired/transferred teacher

<p>I've seen a lot of posts that say that it's ok to get recommendations from former teachers and retired teachers and teachers-about-to-quit and everything, but what if the teacher has ALREADY quit and is teaching in another school now? Is it still ok to ask for a rec from him/her?</p>

<p>And if the teacher is retired, what should be put on the "school" blank in the teacher info section of the Common App's Teacher Evaluation form? ...and come to think of it, what to put there if the teacher has transferred to a different school (as described above)?</p>
